Oslandia: New release for QField : 3.3 “Darién”
sur Planet OSGeo

Oslandia is the main partner of OPENGIS.ch around QField. We are proud today to forward the announcement of the new QField release 3.3 “Darién”. This release introduces a brand new plugin framework that empowers users to customize and add completely new functionalities to their favourite field application.

The plugin framework comes with other new features and improvements for this release, detailed below.
Main highlights
One of the biggest feature additions of this version is a brand new drawing tool that allows users to sketch out important details over captured photos or annotate drawing templates. This was a highly requested feature, which is brought to all supported platforms (Android, iOS, Windows, macOS, and, of course, Linux) with the financial support of the Swiss QGIS user group.

Also landing in this version is support for copying and pasting vector features into and from the clipboard. This comes in handy in multiple ways, from providing a quick and easy way to transfer attributes from one feature to another through matching field names to pasting the details of a captured feature in the field into a third-party messenger, word editing, or email application. Copying and pasting features can be done through the feature form’s menu as well as long pressed over the map canvas. Moreover, a new feature-to-feature attributes transfer shortcut has also been added to the feature form’s menu. Appreciation to Switzerland, Canton of Lucerne, Environment and Energy for providing the funds for this feature.

The feature form continues to gain more functionalities; in this version, the feature form’s value map editor widget has gained a new toggle button interface that can help fasten data entry. The interface replaces the traditional combo box with a series of toggle buttons, lowering the number of taps required to pick a value. The German Archaeological Institut – KulturGutRetter sponsored this feature.

Other improvements in the feature form include support for value relation item grouping and respect for the vector layer attributes’ « reuse last entered value » setting.

Finally, additional features include support for image decoration overlay, a new interface to hop through cameras (front, back, and external devices) for the ‘non-native’ camera, the possibility to disable the 3-finger map rotation gesture, and much more.
User experience improvements
Long-time users of QField will notice the new version restyling of the information panels such as GNSS positioning, navigation, elevation profile, and sensor data. The information is now presented as an overlay sitting on top of the map canvas, which increases the map canvas’ visibility while also achieving better focus and clarity on the provided details. With this new version, all details, including altitude and distance to destination, respect user-configured project distance unit type.

The dashboard’s legend has also received some attention. You can now toggle the visibility of any layer via a quick tap on a new eye icon sitting in the legend tree itself. Similarly, legend groups can be expanded and collapsed directly for the tree. This also permits you to show or hide layers while digitizing a feature, something which was not possible until now. The development of these improvements was supported by Gispo and sponsored by the National Land Survey of Finland.
Plugin framework
QField 3.3 introduces a brand new plugin framework using Qt’s powerful QML and JavaScript engine. With a few lines of code, plugins can be written to tweak QField’s behaviour and add new capabilities. Two types of plugins are possible: app-wide plugins as well as project-scoped plugins. To ensure maximum ease of deployment, plugin distribution has been made possible through QFieldCloud! Amsa provided the financial contribution that brought this project to life.

Our partner OPENGIS.ch will soon offer a webinar to discover how QField plugins can help your field (and business) workflows by allowing you to be even more efficient in the field.

Users interested in authoring plugins or better understanding the framework, can already visit the dedicated documentation page and a sample plugin implementation sporting a weather forecast integration.

Cable Management
sur James Fee GIS Blog

One of the best parts of my iPhone 15 Pro is that it has a USB-C port on it. While I appreciate the lightning port, I have just grown so tired of having to manage so many different ports while traveling. Coupled with my iPad having USB-C and my Apple Watch having a USB-C charging cable, I went ahead and got myself an Anker 3 port USB-C charger (which has a USB-A for those times you need one) allowing me to plug in all my devices at night and just use ordinary USB-C cables.

It is all nice and clean, no longer do I have all different cables for each device. My Kindle is USB-C, my GoPro is USB-C, my battery backup is USB-C and of course my MacBook Pro. I have reduced the cables I travel with because I don’t need one for each device. I do travel with a USB-A to USB-C cable for those times where the airplane doesn’t have USB-C or in an airport or rental car but that tucks away nicely in my travel bag.

But then I just realized my AirPods Pro case is lightning.

Now I could buy a USB-C case for said AirPods, but I want to wait until September and see if there is anything new. So trusty old lightning cable goes back in the bad for now.

Update: I was asked how I charged my AirPods Pro last night, well you can use the Apple Watch charger. Works pretty well but its not a great solution long term.

Apple Maps Gets Topographical
sur James Fee GIS Blog

GIS and Topo maps go hand in hand. From the classic Quad maps, to the National Geographic TOPO! product, to just basic Esri Topo map services, these topographic maps have been part of GIS since the beginning. Google Maps has had their “terrain” layer for a long time (though it seems to be fading out for some reason). Apple with the release of Watch OS 10 and the Ultra 2 added topographical maps to at least the watch ecosystem, but still required an iPhone to download the offline maps.

But yesterday Apple finally closed that hole and added topographical maps (including the trails feature) to iOS.

Now this is very user centric at this point. I expect to see these maps start appearing in apps that use MapKit but to what extent I’m not sure. I use onX Offroad quite a bit and suspect it will continue to use their own

Standards Enabling Collaboration For Global Challenges
sur Open Geospatial Consortium (OGC)

The Open Geospatial Consortium (OGC) is a membership organization dedicated to solving problems faced by people and planet through our shared belief in the power of geography. OGC is one of the world’s largest data and technology consortia and—at 30 years old—one of its longest standing. OGC works with new and established partners and stakeholders to develop and apply accelerated, practical, and implementable solutions to today’s biggest issues, from climate resilience, emergency management, and risk management & insurance, to supply chain logistics, transportation, and health care and beyond.

OGC holds regular member meetings across the globe where geospatial professionals convene to develop standards and advance innovation initiatives led by OGC Members. Most sessions are open to the public and offer valuable opportunities to network with leaders from industry, academia, and government, define future technology trends, and contribute to the open geospatial community.

OGC’s 129th Member Meeting will be held in Montreal, Canada, from June 17–22, 2024. The event kicks off OGC’s 30th anniversary celebrations and carries the theme ‘Standards Enabling Collaboration for Global Challenges.’ Support for the meeting comes from OGC Strategic Member Natural Resources Canada, with additional support from Esri Canada, CAE, Safe Software, and dinner sponsor Bentley Systems.

Eric Loubier, Director General of the Canada Centre for Mapping and Earth Observation at Natural Resources Canada (NRCan) will open the week with a keynote, followed by a 30-year Canadian retrospective by OGC Board Chair Prashant J. Shukle.

“The 129th Member Meeting provides a great opportunity to hear from our incredible Canadian partners and community,” said OGC CEO Peter Rabley. “Some of OGC’s earliest—if not our first—and longest-running supporters have been Canadians and Canadian firms. Our keynote from Eric Loubier and the exciting 30-year Canadian retrospective by Prashant Shukle will serve well to kick off the week’s exciting sessions and discussions.”

“Throughout the 30 years of OGC’s history, Canadians have played a foundational role,” said OGC Board Chair Prashant J. Shukle. “My friend and mentor Dr. Bob Moses, who founded PCI Geomatics, was one of OGC’s first funders and a long-time supporter of OGC. As an emergency room doctor, Bob saw the power of new technologies and data. Critically, he understood that technologies had to work together seamlessly and effectively to really address complex problems.

“Like Bob, many other Canadians instantly saw the powerful role and impact that OGC could have, and I am constantly amazed at their leadership and vision. It is my privilege to honor those Canadians who have gone almost unnoticed here in Canada, but who have fundamentally changed how the world uses technology across so many industries.”

Other highlights of the week will include a Methane Summit, a meeting of the OGC Canada Forum, the popular Future Directions session (this meeting’s topic is AI), as well an abundance of working group sessions on diverse topics such as marine, climate & disaster resilience, and beyond.

The Methane Summit is organized by Steve Liang, Professor and Rogers IoT Research Chair at the University of Calgary and Founder and CTO of OGC Member SensorUp. Steve is spearheading this summit to tackle the critical global challenge of monitoring and tracking methane emissions. The event will feature speakers from McGill University and Environment and Climate Change Canada (ECCC), who will discuss the challenges and opportunities of data management in methane emissions management. Attendees will also be introduced to the Methane Emissions Modeling Language (MethaneML)—a new tool designed to enhance the accuracy and efficiency of methane emissions tracking & reduction. This summit promises to be a significant step forward in our collective efforts to address climate change through innovative data solutions.

The meeting of the OGC Canada Forum is scheduled for June 17 & 18. The Canada Forum is open to all Canadian organizations, regardless of OGC membership status. The sessions have the aim of facilitating collaboration to address Canada’s geospatial needs through capacity building, innovation, standards, and economic growth. Cameron Wilson, Project Manager at Natural Resources Canada (NRCan), will delve into the history, progress, and future priorities of the forum, highlighting key issues crucial for the Canadian community.

Another highlight of the Forum will be a debate addressing the topic: In an era of ever-increasing data availability, there is a pressing need for digital interoperability to solve today’s biggest problems through rapid innovation. Standards only slow this down and are therefore no longer necessary. Debaters include Ed Parsons, Geospatial Technologist at Google, the aforementioned Steve Liang, Will Cadell, CEO of Sparkgeo, and Bilyana Anicic, President of Aurora Consulting. This session promises to offer diverse perspectives on the role that standards can, should, or won’t play in today’s rapidly evolving geospatial landscape.

This meeting’s Future Directions session, held Tuesday morning, is all about AI, with presentations and a panel from Bentley Systems, GeoRoundtable/IEEE GRSS, makepath, and TerraFrame.

Participation in the 129th OGC Member Meeting is welcomed both in-person and remotely. This event is an exciting opportunity to engage in sessions that celebrate three decades of geospatial collaboration and innovation. Attendees will have the chance to learn from, and network with, leading experts from around the world.

Register now for the 129th OGC Member Meeting to be part of OGC’s continued efforts to advance location data and technology and collaboratively address critical global challenges.

QGIS Blog: Danish User Group becomes Flagship Member
sur Planet OSGeo

QGIS User Groups all over the world have become an essential component of the QGIS community. They provide a point of contact for local users and developers and help people connect through localized communication channels or by organizing events.

Another important aspect of users groups is that many of them also have become sustaining members of QGIS.ORG. In total, their contributions account for a significant share of our project budget.

The Danish User Group now has opened a new chapter by becoming the first user group supporting QGIS on the Flagship level. And that’s a reason to celebrate and to reminisce. For example, about the awesome time we had at the first QGIS User Conference organized at the University of Copenhagen campus in Nødebo.

And who can forget how we all struggled to pronounce QGIS 2.16 “Nødebo”?

And how the “ø” upset some services? Good times.

Thank you very much to everyone from the Danish user group and to all the other user groups, small and large, who support QGIS our project and help make it even better for everyone.

A ton of things came to mind from from Apple’s HyperCard (more than anything this made me a programmer) and I even wrote a post about it back in 2006. I don’t think anything on that list is technically incorrect, but I wouldn’t put ArcView 3.x in that list anymore.

BUT, let’s get real here. Each of those software products are amazing in their own right, but I don’t think any of them really moved the needle on spatial like the one I really think impacted the trajectory of what we used to call GIS.

Microsoft SQL Server 2008

Now I know what you’re going to say, why isn’t it PostGIS??? Now PostGIS has been clearly the leader since SQL Server 2008 arrived, but I believe it was SQL Server which changed expectations on paying for a geospatial database (Oracle, SDE or others). I mean I used to have Esri SDE on Oracle, I can’t even remember how expensive that was and how buggy it all was. Microsoft even put spatial into their free version.

I can’t recall the last time I used stand alone SQL Server, mostly my days are PostGIS or some cloud based spatial geodatabase engine. But, the line before SQL Server 2008 and after is clear as day. All of a sudden enterprise grade geodatabase when from niche to normal and spatial ceased to be special. Using Oracle Spatial or Esri ArcSDE always ended with me tossing the server in the trash.

Tim Waters: Vaisigano
sur Planet OSGeo
Vaisigano is a prototype citizen science project focused on fresh water resources by National University of Samoa and The Übersee Museum. On Instagram @s_vaisigano and on Facebook Citizen Science Vaisigano. Vaisigano is the name of the river in Samoa by the University.

Last year I was involved to help develop the prototype mobile-first web app for geolocated data collection ahead of a visit to the field with biologists and students.

Aimed at non specialist university students to use in the field to help survey and record measurements and observations for river quality health along a river in Samoa. The purpose of this first app is to show possibilities and demonstration for future solutions. River and water quality measurements can involve surveys for invertebrates (aquatic insects), pH of the water, turbidity, velocity, temperature etc. Traditionally such surveys were taken, recorded on paper and input later back in the laboratory. A mobile device out in the field can also have documents, multimedia and tutorials to guide users. The project involved research into Citizen Science projects. Many good platforms exist, for example ODK or Kobo which can have very complex and detailed logic for forms but it was decided that a more user friendly and casual approach would be better.

The front page gives a brief outline, a call to action button “Start Collecting”, two summary tables of the latest observations and the latest active users.

The main aims:
- Sustainable – able to run on its own
- Collect data in a continuous manner
- Accessible and easy to use
- Handheld
- Benefit learning for curriculum
- Incorporate reinforcement rewards, feedback
- Surveys should be georeferenced
- Review of previous surveys
Some of the challenges included GPS variability in forest, using mobile devices and water, and bandwidth requirements in the field.

The app showed tips before starting.

The application was designed around 3 types of data forms. physical, biological and chemical

Each form had a time and location which used browser / GPS geolocation. Users could move the location if they wanted.

Physical
- River width
- River depth
- Has it been raining or not?
- What evidence of water user can you see (fishing, boats, use for homes, irrigation, etc)
- What man made structures can you see (e.g. weirds, dams, wells, bypass channels etc
- On the surface. Can you see foam, litter, oil on the surface?
- What land use is around the site (pasture, town, forest etc)
- Flow regime. (pools, ripples, waterfalls, rapids, cascade etc)
- What is the colour of the water (clear, murky etc)
- Estimate the water flow (still, slower, or faster than walking speed etc)
- Turblence of water (calm, turbulent)
- Images looking down stream showing both banks
Chemical
These needed a kit to help complete
- Water temperature
- Water acidity
- Conductivity
- Nitrates
- Phosphates
Biological
- Description of the river bank and vegetation and what % of the river is shade
- What evidence of aquatic life: plants below surface, emerging, floating. Fish, insects etc
- Substrates – boulders, stones, gravel, sand, organic matter etc
- Macroinvertables
  - From kick sampling
  - These allowed users to add a name with a count and attach images.
  - Some species would be pre-populatated in the boxes.
The site has an admin page which allows editing and reviewing of contributions and allows them to download all the data as a spreadsheet and to download the images zipped up.

The site has a simple scoring for users based on number of contributions, and shows feedback of their contributions so that people can see the reports coming in and the nature of them

I mean we’ve been saying it since Elon had bought Twitter, but the deed is done.

The social network formerly known as Twitter has officially adopted X.com for all its core systems. That means typing twitter.com in your browser will now redirect to Elon Musk’s favored domain

I was talking to a good friend over email last month and he had this to say:

The fun days of early twitter and before that blogging certainly made our industry more fun — thanks so much for your key role in that. Sadly those days seem to be gone and I don’t know where to find the modern equivalents.

He is so right, I’m not sure how important my role was in the whole Twitter Geospatial world was, but that grouping we had back then was some of the best sharing of ideas and opinions I’ve ever been part of. I find myself rarely sharing anything spatial on Twitter anymore, mostly it is where I go to complain about the San Francisco Giants, Los Angeles Lakers or Arizona State Sun Devils. And most of that is just shouting into the abyss. This leaves no space for any outlet of my thought and feelings on spatial and the such.

Hence I’m back to blogging, I feel like this has always been the best format for longer form thoughts and given I control the content vs some insane emerald mine heir this is better for my sanity. I am laughing at some of your still using RSS readers (heck I’m one) and having this post show up in your feed after many years. Thanks for never unsubscribing and stay tuned!

GeoServer Team: How to Implement Basic Security in Geoserver
sur Planet OSGeo
GeoSpatial Techno is a startup focused on geospatial information that is providing e-learning courses to enhance the knowledge of geospatial information users, students, and other startups. The main approach of this startup is providing quality, valid specialized training in the field of geospatial information.

( YouTube | LinkedIn | Facebook | X )
How to Implement Basic Security in Geoserver
In this session, we want to discuss the Security section in GeoServer, Defining Users, Groups, and Roles, and Granting rights to created users. If you want to access the complete tutorial, simply click on the link.

Introduction
GeoServer has a robust security subsystem. Most of the security features are available through the Web Administration interface. In the Security panel, you can find links to set user properties and bind data to security rules. The basic idea is that you create users and roles, and then combine them with data rules to enable a specific set of access policies. You can also limit read and write access by role.
Defining users, groups, and roles
Security in GeoServer is based on a role system where each role defines a specific set of functions. You can assign roles to users and groups; that is, assign functions to real people using your system. To ensure data security, you must identify who is accessing your layers and services.

To organize your real users, GeoServer provides you with the user, group, and role concepts. With the first two, you can insert real people into the GeoServer security subsystem, and with roles, you can grant rights to real users.
User definition
In GeoServer, a user is someone entitled to use the system; it may be another software or a real person. When you add a user to the security system, GeoServer stores a username, uniquely identifying the user, a password, and a set of key/value pairs to store general information about it. You can disable a user at any time, preventing him from using the system.
Group definition
A group in GeoServer is a collection of users. It consists of a list of usernames that are part of the group, along with a unique group name that identifies it. Since GeoServer may have a large number of users, assigning roles to each individual user can be challenging. Therefore, groups can be created to simplify the process, allowing roles to be assigned based on the group membership of users.

Note. Considering that there are no dependencies between users, groups, and roles. A group can be disabled, but note that this only removes the roles deriving from the disabled group and does not disable the users belonging to the group.
Roles definition
GeoServer roles are associated with performing certain tasks or accessing particular resources. Roles are assigned to users and groups, authorizing them to perform the actions associated with the role.
Creating users and groups
To fully understand how security works in GeoServer, we will use a typical scenario. We want to restrict access to this data to only the organization’s members. Inside the organization, there are a few people editing data to create new data sets or to update existing ones, and many more members who need to read data to compose maps. There is also a need for an administrator to keep it all working. Lastly, we need to consider that our GeoServer site also contains data that should remain freely available. We will now create the security organization from an unsecured GeoServer as follows:
- In the Security section of the left pane, click the Users, Groups, and Roles link. This link shows you the User Group Services configured. You will find the default service shipped with GeoServer. Click on the Name to edit it.
- Select the Groups tab, then click on Add a new group.
- Enter group_readers as a group name and leave the group Enabled. Do not assign any role to the new group as we will create specific roles later. Press the Save button.
- Repeat the previous step to create the group_editors and group_admins groups. Your list should now show the three groups.
- Now switch to the Users tab. Obviously, it lists the only existing user, that is, admin, as shown in the screen.
- Click on the Add new user link, and add user_admin with a password of your choice, as Data Administrator.
- Add “user_admin” to the “group_admins”, then press the Save button.
- Repeat the previous step to create a user, user_editor as a member of the “group_editors” group, and user_reader as a “group_readers” group member. Your list now shows the three users.
We just created three users for the three groups and this may seem overkill to you. Consider them as templates for real users. In the real world, we do not want to have too many administrators; we will probably need several “user_readers” and “user_editors” processing the data. Now, we need to define what they can do on GeoServer.
Defining roles
A user or a group without any role assigned is useless. Now it is time to create roles and assign them to our users. Please refer to the following points:
- From the User, Groups, and Roles section, select the Roles tab. You will find that two roles already exist. They are the administrative roles assigned to the admin account, and they grant access to all GeoServer configurations. Click on the Edit link
- Switch to the Roles tab, then click on Add new role.
- Enter role_reader as a new role name. We do not need a Parent role. A child role inherits all the rights from the Parent role, making it useful when you want to extend a basic role with more rights. Indeed, we will do this in the next step.
- Press the Save button and then repeat the previous step to create the role_editor role. This time, select “role_reader” as the Parent role.
- Press the Save button and then repeat the previous step to create the role_admin role. This time, select “role_editor” as the Parent role.
- The final step is to associate a role to users or groups. Select the User, Groups, and Roles page from the left pane, then select the Groups list and click on the “group_readers” group to edit it. Add the “role_reader” role to the group and save it.
- Now click on the “group_editors” group and associate it with the role_editor role.
- Finally, associate the “group_admins” group to the “role_admin” role.
By defining roles and associating them to the users, we completed the definition of our organization. Now, we need to explore how data is bound to roles and users.
Accessing data and services
GeoServer supports access control at both the service level and at the per-layer or per-workspace level, allowing for restriction of service operations to authenticate users with specific roles. This helps in ensuring data security and controlling access to different layers or workspaces within the server. When working with layers, you can define rules that specify what a role can do on any specific layer.

The operations controlled are the view, write, and admin access. When granting read access on a layer, you enable a user to add it on a map; while granting write access you enable the user to update, create, and delete features contained in the layer. The admin access level enables the user to update the layer’s configuration.
Layer Security
We want to protect the dataset contained in the test workspace from unauthorized access while leaving the remaining layers freely available to all users. In this section, we will associate layers and roles:
- Navigate to the Data > Security page. The rules list shows the two shipped with the default GeoServer configuration. The *.*.r rule is associated with the * roles. This means that “any user”, including the anonymous one, can access “any layer” from “any workspace” configured on GeoServer. The general format of the rules is: workspace.layer.accessMode.
- Now click on the Add new rule link. In the rule editing page, select test as the Workspace and leave “*” as a Layer. Since we want to protect all layers in this workspace, the Access mode should be Read. Select the “role_reader” role and move it to the right list by clicking on the arrow. Press the Save button to create the reading rule.
- Repeat the previous step to create a writing rule. Select Write as the access mode and “role_editor” as the role.
- Repeat the previous step, then create the administration rule. In other words, select Admin as the Access mode and “role_admin” as the Role.
- Press the Save button, on the rule list page, and then log off from the GeoServer web interface. If you try to access the layer preview anonymously, you won’t see any layers from the test workspace while all the others are still listed.
- Now, log on as “user_reader”, with the password you assigned to him. Going back to the layer preview, you should see the test layers listed. Try the Open Layers preview page for the river layer. It works and you can use the data to compose maps.
- However, “user_reader” can’t edit the styles associated with the layer or any other property. He would need admin rights granted for it; can you guess who the proper user will be?
- Log on to GeoServer as “user_admin”. Now, the left pane is richer than it was when you were “user_reader”, but with fewer features than those visible to the GeoServer’s default admin role. Click on the Layer link; you will see only the layers belonging to the test workspace.
- If you go on Layer preview and select the rivers layer again, can you see the map? Of course, you can. Because of roles inheritance, which you set when creating the roles. So, “role_admin” inherits all the rights from “role_editor”, and hence from “role_reader”.
In this session, we took a brief journey through GeoServer security. we discussed the Security section, Defining Users, Groups, and Roles, and Granting rights to created users in GeoServer. If you want to access the complete tutorial, simply click on the link.

There is no cancer left in me, I am officially “cured”.

Since I am still recovering from surgery and relearning what my GI tract is going to do for the future, I don’t feel entirely cured, but I do feel the weight of wondering about the future lifted off of me.

The future will not hold any more major cancer treatments, just annual screening colonoscopies, and getting better post-surgery.

I truly have had the snack-sized experience, not that I would recommend it to anyone. Diagnosed late February, spit off the back of the conveyor belt in late May. Three months in Cancerland, three months too many.

gvSIG Team: The Ministry of Transport and Sustainable Mobility awards the first National Prize for Geographic Sciences to the gvSIG association
sur Planet OSGeo

The Ministry of Transport and Sustainable Mobility has awarded the gvSIG association the first National Prize for Geographic Sciences, which honors individuals or entities that have made significant contributions through special actions or professional careers in the field of Geographic Sciences. The award resolution will be published shortly in the Official State Gazette (BOE).

This award, which includes a monetary prize of 20,000 euros, is overseen by the National Geographic Information Center at the initiative of the Superior Geographic Council, the governing body of the National Cartographic System. It aims to highlight the contribution, innovation, and impact of advancements achieved in the production, updating, and everyday use of geographic information, its infrastructures, and the derived products and services.

The gvSIG Association is a Spanish non-profit entity dedicated to research, innovation, and development of free and open-source software technologies related to geographic sciences. Based on values such as collaboration, solidarity, and shared knowledge, it has become an international reference, with its catalog of technological solutions for managing geographic information being used practically worldwide.

The gvSIG Association has made significant contributions to the open-source community and geographic technologies, as well as to the promotion of standards. It has developed a range of widely used solutions that have enabled the establishment of a new successful business model, allowing small and medium-sized Spanish companies to offer services and projects in various countries.

Thus, it has carried out projects in more than thirty countries, promoting the internationalization of Spanish companies. Examples of major projects include the Spatial Data Infrastructure of Uruguay, the SDI of the State of Tocantins in Brazil, the application for identifying risks in the movements of Blue Helmets in Mali, the SDI of Repsol for managing renewable energy projects, the Urban Expansion Atlas developed for UN-Habitat, and the current development of the multipurpose cadastral management system of the Dominican Republic.

The National Prize for Geographic Sciences thus recognizes this association for its individual and collective contributions and innovations in the field of geographic sciences and engineering, geomatics, cartography, and geospatial information, as well as its significance and impact on public administrations and society in general.

The jury that recommended granting the award made its decision unanimously after evaluating the merits of a total of fourteen candidates, which raised the deliberations to a high level of excellence. The jury was chaired by the Undersecretary of Transport and Sustainable Mobility and President of the Superior Geographic Council, with the Director General of the IGN and President of the CNIG acting as vice president, and included members representing the governing bodies of the Superior Geographic Council and professional associations in the field of geographic sciences.

Looks like poor Data Analyst ended up in geospatial library dependency hell

It’s interesting to watch it try find a solution.

Alas, no background map appears:

Not giving up yet :)

Woah, what happened here? It claims it created an interactive map in an HTML file.

And indeed it did:

This has been a very interesting experiment for me with many highs and lows. The whole process is a bit hit and miss. But when it does work, it’s fun.

I wasn’t sure what to expect with regards to Data Analyst’s spatial data processing capabilities. Looks like there are enough examples in its training data to find solutions for the basic trajectory analysis problems I asked it solve today, eventually, at least.

What’s the conclusion? Most AI marketing videos are severely overselling the capabilities of these tools. However, that doesn’t mean that they are completely useless, either. I’m looking forward to seeing the age of smaller open source models specifically trained for geospatial analysis to finally make it unnecessary for humans to memorize data analysis library syntax.

gvSIG Team: Algo más que software
sur Planet OSGeo

Recientemente, han otorgado a gvSIG el primer Premio Nacional de Ciencias Geográficas. Un premio que se suma a la larga lista de premios recibidos y que no hace otra cosa que certificar que, sin lugar a duda, gvSIG es uno de los referentes internacionales en materia de Geomática y Geolocalización.

gvSIG tuvo su origen en 2004 en la Generalitat Valenciana. Bueno, realmente en 2004 fue cuando se liberó la primera versión del software de escritorio. La idea empezó a gestarse a finales de 2002.

Un proyecto que empezó siendo un software de escritorio y que hoy se ha convertido en una Suite que permite la gestión de integral de la información geográfica. Junto al inicial cliente de escritorio está el cliente web y la solución para dispositivos móviles; pero esto último que estoy diciendo ya os lo sabéis muy bien los asiduos de este blog.

Por mi parte, hace ya varios años que no estoy vinculado profesionalmente ni a gvSIG ni a trabajos en el ámbito de la geolocalización. Sin embargo, no ocurre así con la componente emocional. Es imposible desligarme de un proyecto que contribuí a poner en marcha desde sus orígenes y a los que he dedicado tantos años de mi vida.

Gracias a gvSIG he podido participar en numerosos congresos y sesiones de trabajo por diferentes lugares del mundo y de España. O que decir de las jornadas internacionales de gvSIG que se celebran todos los años en Valencia y de las que ya se han realizado 19 convocatorias.

Toda esta actividad me ha regalado el privilegio de conocer a mucha, pero que a mucha gente de todo el mundo. Una amplia red de personas con las que hemos colaborado sobre todo en base a unos principios compartidos.

Y es ahora, en el séptimo párrafo cuando llego a lo que realmente quería comentar. Si es que menudo rollo tengo . Recuerdo que en sus inicios se hablaba mucho de los valores de gvSIG. Los más antiguos posiblemente recordaran eso de “Más, mejor y de una forma más justa” “Un modelo de producción basado en la colaboración y en la solidaridad”, “conocimiento compartido vs especulación con conocimiento adquirido” etc.

En la evolución del proyecto cada vez se ha sido menos explícito con estos principios y se ha focalizado más en las dimensiones técnica y comercial. Algo por otra parte que considero natural. Pero sí recuerdo que esos valores eran parte fundamental del pegamento que fue constituyendo la red de amigos y colaboradores de gvSIG. Desde aquella gente que está más próxima al núcleo hasta aquellos colaboradores más puntuales.

Y es que no tengo ninguna duda que estos valores forman parte del ADN de la familia gvSIG. Esto, que algunos llaman capital humano, es el principal activo del proyecto. De ahí, mi alegría y trasladar mi felicitación al equipo de gvSIG por este éxito, que es uno más de los muchos recibidos y de los muchos por recibir.

Oslandia: (Fr) Topographie et topologie dans et autour de QGIS
sur Planet OSGeo
Since 2018 and the arrival of Loïc Bartoletti, Oslandia has accelerated its focus on topography and topology within and around QGIS.

Two questions have driven this focus:
- How to draw directly in GIS by integrating drawing tools inspired by the CAD world into QGIS.
- How to integrate plugins for topographic calculations directly into QGIS.
To address this, Oslandia has worked on several fronts: training, developing open-source plugins, and improvements in QGIS.
1- Plugins
The following plugins were developed by Oslandia or partners, with contributions from Oslandia:
- landsurveycodesimport : [https:]]
  A plugin for surveyors working with the point coding methodology in topography.
- QompliGIS : [https:]]
  A tool to ensure your dataset or plan complies with a specification.
- Total Open Station : [https:]]
  An open-source project initiated by Italian and French archaeologists, it is a tool to convert various formats of survey field books.
- Topaze : [https:]]
  A topometric calculation tool developed with Jean-Marie Arsac (Azimut). It was a proof of concept that such calculations can be done within a GIS.
These plugins can be used at different stages of a project. They can be used all together or only those needed and integrated into workflows.
2- Improvements on QGIS
Oslandia also focuses on improving the core of QGIS. Last years, our teams have worked on:

— Integration of shape tools: circles, ellipses, rectangles, regular polygons, etc.
— Improvement of snapping tools.
— Enhancement of Z and M coordinate support.
— Improvement of topological tools (relationships between geometries).

Coming soon is the possibility to use geometry and topology validation and correction plugins directly in QGIS processing tools, developed by Jacky Volpès and Loïc Bartoletti.
3- Training
Oslandia is QUALIOPI certified and offers a training program around QGIS and QField:
- Drawing: Transition from CAD to GIS with QGIS: https://oslandia.com/formations/qgis3-dessiner-avec-qgis/
- Topography with QGIS (LSCI, Topaze, QompliGIS, Total Open Station)
- QField Training
- Deployment of QField Cloud
« In 2023, 89 people were trained by Oslandia, who recommend our training at 90.9%.»
4- And QField ?
Since our partnership with OPENGIS.ch, Oslandia offers QField Cloud server deployment services, training, and QField support.
5- Coming Soon!
Several technical posts are being prepared: how to open CAD files in a GIS? What are the differences between QField and LSCI? You will find them on our website in the coming weeks.

Additionally, we are preparing a white paper on the topic of migrating from CAD to QGIS, which we should release in September.

Stay tuned!

OPENGIS.ch: The PostgreSQL Connection Service File and Why We Love It
sur Planet OSGeo
The PostgreSQL Connection Service File pg_service.conf is nothing new. It has existed for quite some time and maybe you have already used it sometimes too. But not only the new QGIS plugin PG service parser is a reason to write about our love for this file, as well we generally think it’s time to show you how it can be used for really cool things.
What is the Connection Service File?
The Connection Service File allows you to save connection settings for each so-called “service” locally.

So when you have a database called gis on a local PostgreSQL with port 5432 and username/password is docker/docker you can store this as a service called my-local-gis.
```
# Local GIS Database for Testing purposes
```
[my-local-gis]
host=localhost port=5432 dbname=gis user=docker password=docker

This Connection Service File is called pg_service.conf and is by client applications (such as psql or QGIS) generally found directly in the user directory. In Windows it is then found in the user’s application directory postgresql.pg_service.conf. And in Linux it is by default located directly in the user’s directory ~/.pg_service.conf.

But it doesn’t necessarily have to be there. The file can be anywhere on the system (or on a network drive) as long as you set the environment variable PGSERVICEFILE accordingly:
```
export PGSERVICEFILE=/home/dave/connectionfiles/pg_service.conf 
```
Once you have done this, the client applications will search there first – and find it.

If the above are not set, there is also another environment variable PGSYSCONFDIR which is a folder which is searched for the file pg_service.conf.

Once you have this, the service name can be used in the client application. That means in psql it would look like this:
```
~$ psql service=my-local-gis
psql (14.11 (Ubuntu 14.11-0ubuntu0.22.04.1), server 14.5 (Debian 14.5-1.pgdg110+1))
SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, bits: 256, compression: off)
Type "help" for help.

gis=#
```
And in QGIS like this:

If you then add a layer in QGIS, only the name of the service is written in the project file. Neither the connection parameters nor username/password are saved. In addition to the security aspect, this has various advantages, more on this below.

But you don’t have to pass all of these parameters to a service. If you only pass parts of them (e.g. without the database), then you have to pass them when the connection is called:
```
$psql "service=my-local-gis dbname=gis"
psql (14.11 (Ubuntu 14.11-0ubuntu0.22.04.1), server 14.5 (Debian 14.5-1.pgdg110+1))
SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, bits: 256, compression: off)
Type "help" for help.

gis=#
```
You can also override parameters. If you have a database gis configured in the service, but you want to connect the database web, you can specify the service and explicit the database:
```
$psql "service=my-local-gis dbname=web"
psql (14.11 (Ubuntu 14.11-0ubuntu0.22.04.1), server 14.5 (Debian 14.5-1.pgdg110+1))
SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, bits: 256, compression: off)
Type "help" for help.

web=#
```
Of course the same applies to QGIS.

And regarding the environment variables mentioned, you can also set a standard service.
```
export PGSERVICE=my-local-gis
```
Particularly pleasant in daily work with always the same database.
```
$ psql
psql (14.11 (Ubuntu 14.11-0ubuntu0.22.04.1), server 14.5 (Debian 14.5-1.pgdg110+1))
SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, bits: 256, compression: off)
Type "help" for help.

gis=#
```
And why is it particularly cool?
There are several reasons why such a file is useful:
- Security: You don’t have to save the connection parameters anywhere in the client files (e.g. QGIS project files). Keep in mind that they are still plain text in the service file.
- Decoupling: You can change the connection parameters without having to change the settings in client files (e.g. QGIS project files).
- Multi-User: You can save the file on a network drive. As long as the environment variable of the local systems points to this file, all users can access the database with the same parameters.
- Diversity: You can use the same project file to access different databases with the same structure if only the name of the service remains the same.
For the last reason, here are three use cases.
Support-Case
Someone reports a problem in QGIS on a specific case with their database. Since the problem cannot be reproduced, they send us a DB dump of a schema and a QGIS project file. The layers in the QGIS project file are linked to a service. Now we can restore the dump on our local database and access it with our own, but same named, service. The problem can be reproduced.
INTERLIS
With INTERLIS the structure of a database schema is precisely specified. If e.g. the canton has built the physical database for it and configured a supernice QGIS project, they can provide the project file to a company without also providing the database structure. The company can build the schema based on the INTERLIS model on its own PostgreSQL database and access it using its own service with the same name.
Test/Prod Switching
You can access a test and a production database with the same QGIS project if you have set the environment variable for the connection service file accordingly per QGIS profile.

You create two connection service files.

The one to the test database /home/dave/connectionfiles/test/pg_service.conf:
```
[my-local-gis]
host=localhost
port=54322
dbname=gis-test
```
And the one for the production database /home/dave/connectionfiles/prod/pg_service.conf:
```
[my-local-gis]
host=localhost
port=54322
dbname=gis-productive
```
In QGIS you create two profiles “Test” and “Prod”:

And you set the environment variable for each profile PGSERVICEFILE which should be used (in the menu Settings > Options… and there under System scroll down to Environment

or

If you now use the service my-local-gis in a QGIS layer, it connects the database prod in the “Prod” profile and the database test in the “Test” profile.
The authentication configuration
Let’s have a look at the authentication. If you have the connection service file on a network drive and make it available to several users, you may not want everyone to access it with the same login. Or you generally don’t want any user information in this file. This can be elegantly combined with the authentication configuration in QGIS.

If you want to make a QGIS project file available to multiple users, you create the layers with a service. This service contains all connection parameters except the login information.

This login information is transferred using QGIS authentication.

You also configure this authentication per QGIS profile we mentioned above. This is done via Menu Settings > Options… and there under Authentication:

(or directly where you create the PostgreSQL connection)

If you add such a layer, the service and the ID of the authentication configuration are saved in the QGIS project file. This is in this case mylogin. Of course this name must be communicated to the other users so that they can also set the ID for their login to mylogin.

Of course, you can use multiple authentication configurations per profile.
QGIS Plugin
And yes, there is now a great plugin to configure these services directly in QGIS. This means you no longer have to deal with text-based INI files. It’s called PG service parser:

It finds the connection service file according to the mentioned environment variables PGSERVICEFILE or PGSYSCONFDIR or at its default location.

As well it’s super easy to create new services by duplicating existing ones.
And for the Devs
And what would a blog post be without some geek food? The back end of this plugin is published on PYPI and can be easily installed with pip install pgserviceparser and then be used in Python.

For example to list all the service names.
```
>>> import pgserviceparser
>>> pgserviceparser.service_names()
['my-local-gis', 'another-local-gis', 'opengisch-demo-pg']
```
Optionally you can pass a config file path. Otherwise it gets it by the mentioned mechanism.

Or to receive the configuration from the given service name as a dict.
```
>>> pgserviceparser.service_config('my-local-gis')
{'host': 'localhost', 'port': '54322', 'dbname': 'gis', 'user': 'docker', 'password': 'docker'}
```
There are some more functions. Check them out here on GitHub or in the documentation.
Well then
We hope you share our enthusiasm for this beautiful file – at least after reading this blog post. And if not – feel free to tell us why you don’t in the comments

The layers in the QGIS project file are linked to a service. Now we can restore the dump on our local database and access it with our own, but same named, service. The problem can be reproduced.
INTERLIS
With INTERLIS the structure of a database schema is precisely specified. If e.g. the canton has built the physical database for it and configured a supernice QGIS project, they can provide the project file to a company without also providing the database structure. The company can build the schema based on the INTERLIS model on its own PostgreSQL database and access it using its own service with the same name.
Test/Prod Switching
You can access a test and a production database with the same QGIS project if you have set the environment variable for the connection service file accordingly per QGIS profile.

You create two connection service files.

The one to the test database /home/dave/connectionfiles/test/pg_service.conf:
```
[my-local-gis]
host=localhost
port=54322
dbname=gis-test
```
And the one for the production database /home/dave/connectionfiles/prod/pg_service.conf:
```
[my-local-gis]
host=localhost
port=54322
dbname=gis-productive
```
In QGIS you create two profiles “Test” and “Prod”:

And you set the environment variable for each profile PGSERVICEFILE which should be used (in the menu Settings > Options… and there under System scroll down to Environment

or

If you now use the service my-local-gis in a QGIS layer, it connects the database prod in the “Prod” profile and the database test in the “Test” profile.
The authentication configuration
Let’s have a look at the authentication. If you have the connection service file on a network drive and make it available to several users, you may not want everyone to access it with the same login. Or you generally don’t want any user information in this file. This can be elegantly combined with the authentication configuration in QGIS.

If you want to make a QGIS project file available to multiple users, you create the layers with a service. This service contains all connection parameters except the login information.

This login information is transferred using QGIS authentication.

You also configure this authentication per QGIS profile we mentioned above. This is done via Menu Settings > Options… and there under Authentication:

(or directly where you create the PostgreSQL connection)

If you add such a layer, the service and the ID of the authentication configuration are saved in the QGIS project file. This is in this case mylogin. Of course this name must be communicated to the other users so that they can also set the ID for their login to mylogin.

Of course, you can use multiple authentication configurations per profile.
QGIS Plugin
And yes, there is now a great plugin to configure these services directly in QGIS. This means you no longer have to deal with text-based INI files. It’s called PG service parser:

It finds the connection service file according to the mentioned environment variables PGSERVICEFILE or PGSYSCONFDIR or at its default location.

As well it’s super easy to create new services by duplicating existing ones.
And for the Devs
And what would a blog post be without some geek food? The back end of this plugin is published on PYPI and can be easily installed with pip install pgserviceparser and then be used in Python.

For example to list all the service names.
```
>>> import pgserviceparser
>>> pgserviceparser.service_names()
['my-local-gis', 'another-local-gis', 'opengisch-demo-pg']
```
Optionally you can pass a config file path. Otherwise it gets it by the mentioned mechanism.

Or to receive the configuration from the given service name as a dict.
```
>>> pgserviceparser.service_config('my-local-gis')
{'host': 'localhost', 'port': '54322', 'dbname': 'gis', 'user': 'docker', 'password': 'docker'}
```
There are some more functions. Check them out here on GitHub or in the documentation.
Well then
We hope you share our enthusiasm for this beautiful file – at least after reading this blog post. And if not – feel free to tell us why you don’t in the comments

Martin Davis: RelateNG Performance
sur Planet OSGeo
A previous post introduced a new algorithm in the JTS Topology Suite called RelateNG. It computes topological relationships between geometries using the Dimensionally-Extended 9 Intersection Model (DE-9IM) model.
This algorithm is fundamental to a large proportion of spatial queries executed in numerous geospatial environments. It would not be surprising to learn that the Relate algorithm is executed billions of times per day across the world's data centres. Given this, performance is a critical metric.
The original JTS RelateOp algorithm was hamstrung by its design, which required computing a full topology graph for each relationship evaluation. The subsequent development of PreparedGeometry provided a significant performance boost for common spatial predicates such as intersects and covers. A useful side-effect is that it is less susceptible to geometric robustness problems. However, it has some drawbacks:
- it only implements a small set of predicates
- the design does not easily extend to more complex predicates
- it does not support GeometryCollection inputs
- it is a completely separate codebase to the general-purpose RelateOp, which increases maintenance effort and increases the risk of bugs and behaviour discrepancies
RelateNG solves all of these problems. In addition, it provides much better performance for non-prepared (stateless) calls. This is important for systems which do not execute spatial queries in a stateful way (due to architectural limitations, or simply lack of attention to performance), and thus cannot use prepared mode.Performance TestsHere are some examples of performance metrics. Note that the data used in the tests is sometimes subsetted to avoid skewing the results with many false results due to non-interaction between the input geometries. This reflects the typical deployment of these predicates in systems which perform a primary extent filter (i.e. via a spatial index) before executing the full predicate.Some of datasets are in geodetic coordinates, which strictly speaking JTS does not handle. But this does not matter for the purposes of performance testing.Point / PolygonThis test queries a MultiPolygon of the outline of Europe (including larger islands) against a synthetic dataset of random points. The test evaluates the intersects predicate, which is really the only one of interest in the Point / Polygon case.
The test data metrics are:
- Query MultiPolygon: 461 polygons, 22,675 vertices
- Target Points: 10,000 points
Timings

Op Intersects Intersects Prep

Relate 61.7 s 21 ms

RelateNG 0.1 s 19 ms

The result clearly shows the enormous improvement in the stateless case, since RelateNG does not build topology on the input polygon. The results are very similar in the prepared case. This is as expected, since both codebases run a simple Point-in-Polygon test using a cached spatial index.Line / LineThis test uses a dataset of major rivers of the continental United States. A single river mainstem is queried against a subset of river branches using the intersects and touches relationships, in stateless and prepared modes.
The test data metrics are:
- Query Line: 6,975 vertices
- Target Lines: 407 lines with 47,328 vertices
Timings (per 100 executions of the operation)

Op Intersects Intersects Prep Touches Touches Prep

Relate 38.2 s 133 ms 36 s N/A

RelateNG 1.18 s 142 ms 2.05 s 2.03 s

This shows the much better performance of RelateNG. RelateNG can evaluate touches in prepared mode, but the performance is similar to stateless mode, since currently indexes are not cached for Line/Line cases. This could be improved in a future release.Polygon / PolygonThis test uses data from two polygonal datasets:
- The Britsh Columbia Bedrock Geology polygonal coverage
- The GADM Level 2 boundaries for Canada
The tests query an administrative unit polygon against a subset of Bedrock polygons which intersect its extent, using intersects and covers in stateless and prepared modes.
The test data metrics are:
- GADM unit: 4,017 vertices
- Bedrock polygons: 4,318 polygon with 337,650 vertices
Timings (per 100 executions of the operation)

Op Intersects Intersects Prep Covers Covers Prep

Relate 61.7 s 534 ms 54.9 s 842 ms

RelateNG 5.8 s 595 ms 6.4 s 943 ms
Polygon / Polygon - Custom Relate PatternThe tests shows the ability of RelateNG to efficiently evaluate arbitrary Relate Intersection Matrix patterns. In this case, the pattern used is F***0****, which corresponds to a relationship which could be called "point-touches": two geometries have boundaries which intersect in only one (or more) points (dimension 0), but whose interiors do not intersect.
This test uses data from The GADM Level 1 boundaries for Canada. This has the advantage that Canada contains a rare example of 4 boundaries meeting at a single point (the jurisdictions of Saskatchewan, Manitoba, Northwest Territories, and Nunavut).
The test data metrics are:
- GADM Canada Level 1: 13 polygons, 4,005,926 vertices
Timings

Op F***0**** F***0**** Prep
Relate 504 s N/A
RelateNG 9.8 s 6.6 s

As expected, for this test RelateNG is far more performant than Relate. This is due to its ability to analyze Intersection Matrix patterns and perform only topology tests that are necessary, as well as not building a full topological structure of the inputs. The test shows the effect of caching spatial indexes in prepared mode, although stateless mode is very efficient as well. Analysis of ResultsClearly RelateNG is far more performant than Relate when running in non-prepared mode. The PreparedGeometry implementation is slightly faster (which confirms the efficiency of its original design), but not by very much. The difference may be a consequence of the general-purpose and thus more complex code and data structures in RelateNG. Closing this gap may be an area for future research.One thing is certain: the RelateNG algorithm design provides much more scope for adding case-specific optimizations. If you have a significant use case which could be improved by further targeted optimization improvements, let me know in the comments!It will be interesting to re-evaluate these tests once RelateNG is ported to GEOS. Sometimes (but not always) a C++ implementation can be significantly faster than Java, due to more opportunities for code and compiler optimization.

Fernando Quadro: O que é o DATUM?
sur Planet OSGeo

O DATUM é um termo utilizado na área da geodésica que se refere a um sistema de referência utilizado para determinar as coordenadas geográficas na superfície da Terra. Ele é fundamental para a realização de medições precisas e confiáveis em projetos de cartografia e geoprocessamento.

É baseado em alguns princípios fundamentais:

Considera a Terra como um elipsoide, ou seja, um corpo sólido de formato semelhante a uma esfera achatada nos polos e alongada no equador.
Leva em conta a gravidade terrestre, rotação da Terra e a distribuição de massa em seu interior.

A diferença entre um datum e outro é baseada em modelos matemáticos distintos da forma e dimensões da Terra e do fator adicional da projeção, seja por razões históricas, seja para garantir uma representação gráfica mais proporcionada; tomando como exemplo o Japão, onde usam um ponto da projeção que não está no centro da Terra, mas em algum lugar sob o Japão, isto permite uma menor distorção numa projeção de uma esfera sobre plano quando o Japão é representado, mas no entanto o uso dessa projeção para os Estados Unidos ou para o Brasil resultaria em um mapa muito estranho.

O uso do DATUM possibilita diversos benefícios, veja:

Precisão nas medições
Padronização global
Compatibilidade com Sistemas de Posicionamento Global (GPS)
Melhoria na precisão dos mapas

O DATUM apresenta diversos benefícios, no entanto, seu uso também apresenta desafios, como a necessidade de atualização constante e a complexidade dos cálculos.

O futuro do DATUM está ligado ao avanço da tecnologia, o que permitirá realizar medições ainda mais precisas e eficientes.

Fernando Quadro: O papel do Machine Learning no GIS
sur Planet OSGeo

No domínio dos Sistemas de Informação Geográfica (GIS), o Machine Learning não é apenas uma palavra da moda, é uma força transformadora. É a chave para desbloquear todo o potencial dos dados geoespaciais, transformando conjuntos de dados vastos e complexos em insights acionáveis. Vamos nos aprofundar nos tipos de algoritmos de machine learning e suas aplicações em contextos geoespaciais.

Aprendizagem supervisionada: A aprendizagem supervisionada é semelhante a ter um guia experiente no deserto de dados. Com conjuntos de dados rotulados, os algoritmos aprendem a prever resultados com base em exemplos anteriores. É perfeito para:
Mapeamento de Habitat de Espécies: Prever onde certas espécies podem prosperar.
Categorização da Cobertura do Solo: Classificação de áreas com base na vegetação, desenvolvimento urbano ou corpos d’água.
Previsão Climática: Estimativa de padrões futuros de temperatura e precipitação.

Aprendizagem não supervisionada: Algoritmos de aprendizagem não supervisionados são os exploradores intrépidos, encontrando estruturas ocultas em territórios desconhecidos de dados não rotulados. Eles se destacam em:
Segmentação de imagens: Divisão de milhões de imagens de satélite em clusters significativos.
Detecção de anomalias: Identificação de padrões incomuns que possam indicar mudanças ambientais ou desenvolvimento urbano.

Aprendizado profundo: O aprendizado profundo se aprofunda nos dados, usando redes neurais em camadas para processar informações de uma forma que imita o cérebro humano. Sua habilidade é evidente em:
Classificação de Imagens: Distinguir entre diferentes usos do solo em imagens de satélite.
Detecção de Objetos: Identificação e localização de objetos como veículos ou edifícios em fotos aéreas.
Análise de Séries Temporais: Monitoramento de mudanças ao longo do tempo, como desmatamento ou expansão urbana.

Algoritmos Comuns: Os algoritmos mais comumente usados em análise geoespacial incluem:
Random Forest: um método de conjunto robusto, ótimo para tarefas de classificação e regressão.
Regressão Linear: Ideal para prever variáveis contínuas, como tendências de temperatura.
Regressão Logística e Árvores de Decisão: Útil para classificação binária, como áreas propensas a inundações.
K-Nearest Neighbors: Um método simples, mas eficaz para classificação com base na proximidade.
Naïve Bayes: Uma abordagem probabilística frequentemente usada para classificação de texto e filtragem de spam.
K-Means Clustering: Um algoritmo não supervisionado que agrupa dados em k clusters distintos.

À medida que continuamos a aproveitar esses algoritmos, não estamos apenas mapeando o mundo, estamos moldando-o. O futuro da análise geoespacial está aqui e é inteligente, dinâmico e incrivelmente emocionante.

Registrations Open for OGC’s July 2024 Open Standards Code Sprint
sur Open Geospatial Consortium (OGC)

The Open Geospatial Consortium (OGC) invites developers and other contributors to the July 2024 Open Standards Code Sprint, to be held from July 10-12 in London and online. Participation is free and open to the public, with travel support funding available to select participants. Sponsorship opportunities are also available.

The Code Sprint is sponsored by OGC Principal Member Google at the Silver Level, with additional Strategic Member support from Natural Resources Canada (NRCan).

This will be a collaborative and inclusive event to support the development of open Standards and applications that implement those Standards. All OGC Standards are in scope for this Code Sprint, including OGC API Standards. The Sprint will feature three special tracks on Data Quality & Artificial Intelligence, Validators, and the Map Markup Language (MapML).

OGC Code Sprints experiment with emerging ideas in the context of geospatial Standards and help improve interoperability of existing Standards by experimenting with new extensions or profiles. They are also used for building proofs-of-concept to support standards development activities and the enhancement of software products.

Non-coding activities such as testing, working on documentation, or reporting issues are welcome during the Code Sprint. OGC Sprints also provide an opportunity to onboard developers that are new to OGC Standards, through the sprints’ mentor streams.

Organizations are invited to sponsor the Code Sprint. A range of packages are available offering different opportunities for organizations to support the geospatial development community while promoting their products or services. Visit the Event Sponsorship page for more information.

A one-hour pre-event webinar will take place at 14:00 BST (UTC+1) on June 13. The webinar will outline the scope of work for the Code Sprint and provide an overview of the specifications that will be its focus. The pre-event webinar will take place on OGC’s Discord server.

Travel Support Funding is available for selected participants. Participants interested in receiving travel support funding should indicate their interest on the registration form. Any participant applying for funding will need to submit their registration form by June 30. Applicants will be notified within 2 weeks of their application whether travel support will be available to them or not.

The code sprint will begin with an onboarding session at 09:00 (UTC+1) on July 10, and ends at 17:00 (UTC+1) on July 12. Registration for in-person participation closes at 17:00 (UTC+1) on July 3. Registration for remote participation will remain open throughout the Code Sprint.

Registration is available on the July 2024 Code Sprint website. To learn more about future and previous OGC code sprints, visit the OGC Developer Events Wiki, the OGC Code Sprints Website, or join OGC’s Discord server.

Fernando Quadro: Geoprocessamento na Saúde
sur Planet OSGeo

A localização de eventos de saúde no espaço geográfico com base em mapas não é recente. Em 1854, o médico John Snow investigou no bairro de Soho, em Londres, um surto de cólera. Ele mapeou com base nos croquis dos quarteirões, as casas atingidas e relacionou com as pessoas que beberam água de uma fonte na Broad Street.

Logo, percebeu que aquele surto em particular ocorrera em torno de uma bomba de água compartilhada que a maioria dos habitantes usava para coletar água para beber e lavar. Essa foi a primeira vez que um mapa foi usado para melhor compreensão de uma doença e estabelecer medidas de controle.

Várias são as possibilidades do uso do geoprocessamento na saúde:

Serviços de saúde,
Saúde ambiental,
Epidemiologia de doenças crônicas não transmissíveis,
Epidemiologia de doenças transmissíveis,
Identificação de áreas de risco,
Entre outros…

A melhora e o aumento na disponibilidade de bases de dados e dos SIG trouxeram ganhos importantíssimos para aplicação do geoprocessamento na área da saúde. Podemos citar os Sistemas de Informação em Saúde que abarcam dados sobre nascimentos, óbitos e doenças de notificação compulsória, entre eles:

Sistema de Informação de Mortalidade (SIM),
Sistema de Nascidos Vivos (SINASC) ,
Sistema de Informação de Agravos de Notificação (SINAN).

As possibilidades de técnicas disponíveis em SIGs robustos, permitem análises que são úteis na identificação de áreas de risco para determinados agravos, bem como na análise destes que busquem relação com variáveis ambientais extraídas de informações sobre uso e ocupação do solo ou de variáveis climáticas, extraídas de produtos de sensoriamento remoto e de métodos de reanálise para o monitoramento climático; ou na combinação de variáveis, ambientais, climáticas socioeconômicas a partir do uso de modelos estatísticos espaciais que permite tratar a heterogeneidade espacial e espaço temporal, levando em conta tanto a vizinhança (a dependência espacial) como a existência de estruturas hierárquicas de dados em questão.

Em resumo, a aplicação do geoprocessamento e das técnicas de análise espacial associadas ao acesso livre e gratuito de SIGs e de inúmeras fontes de dados, vem abrindo oportunidades de uso na área de saúde pública, não somente para pesquisadores em seus estudos, mas especialmente para os profissionais que atuam na área da saúde.
