      On a dark night in July, 1893, Count Dracula embarked on a long, secret journey from Transylvania aboard the ill-fated ship Demeter. Unbeknownst to the unsuspecting crew of the Demeter, a malevolent force lay hidden in the ship's hold—a coffin filled with the cursed soil of Dracula's homeland, concealing the vampire lord himself.By the time the Demeter's ghostly silhouette loomed over the

    • sur Fernando Quadro: O papel do Machine Learning no GIS

      Publié: 23 May 2024, 2:00pm CEST

      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.

    • sur Registrations Open for OGC’s July 2024 Open Standards Code Sprint

      Publié: 22 May 2024, 3:00pm CEST par Simon Chester

      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.

    • sur Fernando Quadro: Geoprocessamento na Saúde

      Publié: 22 May 2024, 2:00pm CEST

      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.

    • sur Free and Open Source GIS Ramblings: New Trajectools 2.1 and MovingPandas 0.18 releases

      Publié: 20 May 2024, 5:07pm CEST

      Today marks the 2.1 release of Trajectools for QGIS. This release adds multiple new algorithms and improvements. Since some improvements involve upstream MovingPandas functionality, I recommend to also update MovingPandas while you’re at it.

      If you have installed QGIS and MovingPandas via conda / mamba, you can simply: 

      conda activate qgis
mamba install movingpandas=0.18

      Afterwards, you can check that the library was correctly installed using:

      import movingpandas as mpd
      mpd.show_versions()
      Trajectools 2.1

      The new Trajectools algorithms are:

      • Trajectory overlay — Intersect trajectories with polygon layer
      • Privacy — Home work attack (requires scikit-mobility)
        • This algorithm determines how easy it is to identify an individual in a dataset. In a home and work attack the adversary knows the coordinates of the two locations most frequently visited by an individual.
      • GTFS — Extract segments (requires gtfs_functions)
      • GTFS — Extract shapes (requires gtfs_functions)

      Furthermore, we have fixed issue with previously ignored minimum trajectory length settings.

      Scikit-mobility and gtfs_functions are optional dependencies. You do not need to install them, if you do not want to use the corresponding algorithms. In any case, they can be installed using mamba and pip: 

      mamba install scikit-mobility
pip install gtfs_functions
      MovingPandas 0.18

      This release adds multiple new features, including

      • Method chaining support for add_speed(), add_direction(), and other functions
      • New TrajectoryCollection.get_trajectories(obj_id) function
      • New trajectory splitter based on heading angle
      • New TrajectoryCollection.intersection(feature) function
      • New plotting function hvplot_pts()
      • Faster TrajectoryCollection operations through multi-threading
      • Added moving object weights support to trajectory aggregator

      This week, we start a series with the artist Christian Guemy. C215, Christian Guemy’s artistic pseudonym, is a French street artist renowned for his unique blend of historical figures and vintage map boards. By transforming these weathered maps into canvases, C215 breathes new life into forgotten objects while leaving a powerful commentary on the passage of time and the enduring legacy of influential figures.

      A Fusion of Past and Present

      C215’s signature style involves meticulously stencilling portraits of iconic individuals—activists, scientists, artists, and more—directly onto the aged surfaces of map boards. These maps, often discarded or forgotten, become powerful symbols of the past. By juxtaposing these historical figures with the faded geography, C215 compels viewers to contemplate the connection between the past, present, and future.

      A Street Art Pioneer

      C215 is considered a pioneer of the French street art movement. He emerged in the early 2000s, bringing his art form to the streets of Paris and beyond. His work can be found adorning walls, buildings, and even abandoned spaces throughout Europe and across the globe.

      More Than Just Portraits

      While portraits are a defining element of C215’s art, his work delves into social commentary. He has used his stencils to address issues of war, poverty, and environmental degradation. The weathered maps themselves become a metaphor for the fragility of our world and the need to learn from the past.

      C215’s art transcends the boundaries of traditional street art. By using vintage map boards as his canvas, he creates a powerful dialogue between past and present, reminding us of the enduring impact of history’s figures and the importance of learning from their legacies.

      For further exploration, you can search online for:

    • sur Martin Davis: JTS Topological Relationships - the Next Generation

      Publié: 16 May 2024, 11:41pm CEST

      The most fundamental and widely-used operations in the JTS Topology Suite are the ones that evaluate topological relationships between geometries.  JTS implements the Dimensionally-Extended 9 Intersection Model (DE-9IM), as defined in the OGC Simple Features specification, in the RelateOp API.  

      DE-9IM matrix for overlapping polygons

      The RelateOp algorithm was the very first one implemented during the initial JTS development, over 20 years ago.  At that time it was an appealing idea to implement a general-purpose topology framework (the GeometryGraph package), and use it to support topological predicates, overlay, and buffering.  However, some disadvantages of this approach have become evident over time:

      • the need to create a topological graph structure limits the ability to improve performance. This has led to the implementation of PreparedGeometry - but that adds further complexity to the codebase, and supports only a limited set of predicates.
      • a large number of code dependencies make it hard to fix problems and improve semantics
      • constructing a full topology graph increases exposure to geometric robustness errors
      • GeometryCollections are not supported (initially because the OGC did not define the semantics for this, and now because adding this capability is difficult)
      There's an extensive list of issues relating (ha!) to RelateOp here.
      The importance of this functionality is especially significant since the same algorithm is implemented in GEOS.  That codebase is used to evaluate spatial queries in popular spatial APIs such as Shapely and R-sf, and numerous systems such as PostGIS, DuckDB, SpatialLite, QGIS, and GDAL (to name just a few).  It would not be surprising to learn that the RelateOp algorithm is executed billions of times per day across the world's CPUs.

      During the subsequent years of working on JTS I realized that there was a better way to evaluate topological relationships.  It would required a ground-up rewrite, but would avoid the shortcomings of RelateOp and provide better performance and a more tractable codebase.  Thanks to my employer Crunchy Data I have finally been able to make this idea a reality.  Soon JTS will provide a new algorithm for topological relationships called RelateNG.

      Key Features of RelateNG

      The RelateNG algorithm incorporates a broad spectrum of improvements over RelateOp in the areas of functionality, robustness, and performance.  It provides the following features:

      • Efficient short-circuited evaluation of topological predicates (including matching custom DE-9IM matrix patterns)
      • Optimized repeated evaluation of predicates against a single geometry via cached spatial indexes (AKA "prepared mode")
      • Robust computation (only point-local geometry topology is computed, so invalid topology does not cause failures)
      • GeometryCollection inputs containing mixed types and overlapping polygons are supported, using union semantics.
      • Zero-length LineStrings are treated as being topologically identical to Points.
      • Support for BoundaryNodeRules.
      Using the RelateNG API

      The main entry point is the RelateNG class.  It supports evaluating topological relationships in three different ways:

      • Evaluating a standard OGC named boolean binary predicate, specified via a TopologyPredicate instance.  Standard predicates are obtained from the RelatePredicate factory functions intersects, contains, overlaps, etc.
      • Testing an arbitrary DE-9IM relationship by matching an intersection matrix pattern (e.g. "T**FF*FF*", which is the pattern for a relation called Contains Properly).
      • Computing the full value of a DE-9IM IntersectionMatrix.
      RelateNG operations can be executed in two modes: stateless and prepared.  Stateless mode is provided by the relate static functions, which accept two input geometries and evaluate a predicate.  For prepared mode, a single geometry is provided to the prepare functions to create a RelateNG instance.  Then the evaluate instance methods can be used to evaluate spatial predicates on a sequence of geometries. The instance creates spatial indexes (lazily) to make topology evaluation much more efficient.  Note that even stateless mode can be significantly faster than the current implementation, due to short-circuiting and other internal heuristics.
      Here is an example of matching an intersection matrix pattern, in stateless mode:
      boolean isMatched = RelateNG.relate(geomA, geomB, "T**FF*FF*");
      Here is an example of setting up a geometry in prepared mode, and evaluating a named predicate on it:
      RelateNG rng = RelateNG.prepare(geomA);
      for (Geometry geomB : geomSet) {
          boolean predValue = rng.evaluate(geomB, RelatePredicate.intersects());
      }

      Rolling It Out

      It's exciting to launch a major improvement on such a core piece of spatial functionality.  The Crunchy spatial team will get busy on porting this algorithm to GEOS.  From there it should get extensive usage in downstream projects.  We're looking forward to hearing feedback from our own PostGIS clients as well as other users.  We're always happy to be able to reduce query times and equally importantly, carbon footprints.  

      In further blog posts I'll describe the RelateNG algorithm design and provide some examples of performance metrics.

      Future Ideas

      The RelateNG implementation provides an excellent foundation to build out some interesting extensions to the fundamental DE-9IM concept.

      Extended Patterns

      The current DE-9IM pattern language is quite limited.  In fact, it's not even powerful enough to express the standard named predicates.  It could be improved by adding features like:

      • disjunctive combinations of patterns.  For example, touches is defined by  "FT******* | F**T***** | F***T****"
      • dimension guards to specify which dimensions a pattern applies to.  For example, overlaps is defined by "[0,2] T*T***T** | [1] 1*T***T**"
      • while we're at it, might as well support dotted notation and spaces for readability; e.g. "FT*.***.***"

      Approximate Spatial RelationshipsA requirement that comes up occasionally is to compute approximate spatial relationships between imprecise data using a distance tolerance.  This is useful in datasets where features don't match exactly due to data inaccuracy. Because RelateNG creates topology only in the neighbourhood of specified points, it should be possible to specify the neighbourhood size using a distance tolerance.  Essentially, vertices and line intersections will "snap together" to determine the effective topology.  Currently within-distance queries are often used to compute "approximate intersects".  Adding a distance tolerance capability to RelateNG will allow other kinds of approximate relationships to be evaluated as well.

      Further Performance Optimizations?

      A challenge with implementing algorithms over a wide variety of spatial types and use cases is how to provide general-purpose code which matches (or exceeds) the efficiency of more targeted implementations.  RelateNG analyzes the input geometries and the predicate under evaluation to tune strategies to reduce the amount of work needed to evaluate the DE-9IM.  It may be that profiling specific use cases reveals further hotspots in the code which can be improved by additional optimizations.  

      Curve Support

      GEOS has recently added support for representing geometries with curves.  The RelateNG design is modular enough that it should be possible to extend it to allow evaluating relationships for geometries with curves.

      Um software capaz de identificar, a partir de imagens aéreas, caixas d’água sobre telhados ou lajes e piscinas em áreas abertas foi desenvolvido por pesquisadores brasileiros com o auxílio de ferramentas de Inteligência Artificial. A proposta é usar esse tipo de imagem como indicador de zonas especialmente vulneráveis a infestações do mosquito Aedes aegypti, transmissor de doenças como dengue, zika e chikungunya. Além disso, a estratégia desponta como potencial alternativa para um mapeamento socioeconômico dinâmico das cidades – um ganho para diferentes políticas públicas.

      A pesquisa, apoiada pela Fapesp, foi conduzida por profissionais da USP, da Universidade Federal de Minas Gerais (UFMG) e da Superintendência de Controle de Endemias (Sucen) da Secretaria de Estado da Saúde de São Paulo.

      Entre outras coisas, o grupo almeja incorporar outros elementos para serem detectados nas imagens e quantificar as taxas reais de infestação do Aedes aegypti em uma dada região para refinar e validar o modelo. “Nós esperamos criar um fluxograma que possa ser aplicado em diferentes cidades para encontrar áreas de risco sem a necessidade de visitas domiciliares, prática que gasta muito tempo e dinheiro público”.

      Apesar de as fotos aéreas de Campinas terem sido obtidas com um drone, espera-se que, no futuro, a estratégia testada nessa pesquisa recorra apenas às imagens de satélite.

      No estudo em Belo Horizonte, as imagens de satélite foram empregadas com sucesso – elas precisam de alta resolução para que o computador consiga identificar os padrões.

      Embora esse tipo de metodologia pareça custoso, ele gera uma potencial economia ao dispensar a necessidade de visitas presenciais para mapear, casa por casa, áreas suscetíveis à dengue. Em vez disso, os agentes de saúde aproveitariam as informações obtidas remotamente – e processadas com a Inteligência Artificial – para se dirigir aos locais prioritários com mais assertividade.

      At OPENGIS.CH, we’ve been working lately on improving the DXF Export QGIS functionality for the upcoming release 3.38. In the meantime, we’ve also added nice UX enhancements for making it easier and much more powerful to use!

      Let’s see a short review.

      DXF Export app dialog and processing algorithm harmonized

      You can use either the app dialog or the processing algorithm, both of them offer you equivalent functionality. They are now completely harmonized!

      Export settings can now be exported to an XML file

      You can now have multiple settings per project available in XML, making it possible to reuse them in your workflows or share them with colleagues.

      Load DXF settings from XML. All settings are now well remembered between dialog sessions

      QGIS users told us there were some dialog options that were not remembered between QGIS sessions and had to be reconfigured each time. That’s no longer the case, making it easier to reuse previous choices.

      “Output layer attribute” column is now always visible in the DXF Export layer tree

      We’ve made sure that you won’t miss it anymore.

      DXF Export, output layer attribute Possibility to export only the current map selection

      Filter features to be exported via layer selection, and even combine this filter with the existing map extent one.

      DXF Export algorithm, use only selected features Empty layers are no longer exported to DXF

      When applying spatial filters like feature selection and map extent, you might end up with empty layers to be exported. Well, those won’t be exported anymore, producing cleaner DXF output files for you.

      Possibility to override the export name of individual layers

      It’s often the case where your layer names are not clean and tidy to be displayed. From now on, you can easily specify how your output DXF layers should be named, without altering your original project layers.

      Override output layer names for DXF export.

      We’ve also fixed some minor UX bugs and annoyances that were present when exporting layers to DXF format, so that we can enjoy using it. Happy DXF exporting!

      We would like to thank the Swiss QGIS user group for giving us the possibility to improve the important DXF part of QGIS ???

      Scanxiety.

      This is where I am right now. Scanxiety.

      Each stage of the cancer experience is marked by a particular set of tests, of scans.

      I actually managed to get through my first set of scans surprisingly calmly. After getting diagnosed (“there’s some cancer in you”), they send you for “staging”, which is an MRI and CT scan.

      These scans both involve large, Star Trek seeming machines, which make amazing noises, and in the case of the CT machine I was put through was decorated with colorful LED lights by the manufacturer (because it didn’t look whizzy enough to start with?).

      MRI

      I kind of internalized the initial “broad-brush” staging my GI gave me, which was that it was a tumor caught early so I would be early stage, so I didn’t worry. And it turned out, that was a good thing, since the scans didn’t contradict that story, and I didn’t worry.

      The CT scan, though, did turn up a spot on my hip bone. “Oh, that might be a bone cancer, but it’s probably not.” Might be a bone cancer?!?!?

      How do you figure out if you have “a bone cancer, but it’s probably not”? Another cool scan, a nuclear scan, involving being injected with radioactive dye (frankly, the coolest scan I have had so far) and run through another futuristic machine.

      Bone Scan

      This time, I really sweated out the week between the scan being done and the radiology coming back. And… not bone cancer, as predicted. But a really tense week.

      And now I’m in another of those periods. The result of my major surgery is twofold: the piece of me that hosted my original tumor is now no longer inside of me; and, the lymph nodes surrounding that piece are also outside of me.

      They are both in the hands of a pathologist, who is going to tell me if there is cancer in the lymph nodes, and thus if I need even more super unpleasant attention from the medical system in the form of several courses of chemotherapy.

      The potential long term side effects of the chemotherapy drugs used for colorectal cancers include permanent “peripheral neuropathy”, AKA numbness in the fingers and toes. Which could put a real crimp in my climbing and piano hobbies.

      Climb

      So as we get closer to getting that report, I am experiencing more and more scanxiety.

      If I escape chemo, I will instead join the cohort of “no evidence of disease” (NED) patients. Not quite cured, but on a regular diet of blood work, scans, and colonoscopy, each one of which will involve another trip to scanxiety town. Because “it has come back” starts as a pretty decent probability, and takes several years to diminish to something safely unlikely.

      Yet another way that cancer is a psychological experience as well as a physical one.

      Talk to you again soon, inshalla.

      Cancer is a mind fuck.

      I mean, it’s a body fuck too, obviously, but the early experience for me has been of weird gyrations of mental health and mood with each passing day.

      The first thing I did was the first thing everyone does – look up all the different probabilities of five year survival, because that’s what is at the top of the Google search.

      With a stage two diagnosis (hard to know if that’s actually what I have, though) Google says I have a 10% chance of dying over the next five years.

      That feels like… a lot? A scary amount.

      Rowing

      But wait, here’s an fact – my odds of dying just in the ordinary course of affairs over the next five years are about 4.5%.

      Does that stop me from being 1000% more terrified, on a daily basis, since receiving my diagnosis? No it does not.

      A good deal of that terror, I think, is that cancer promises a patient a long and painful interaction with a medical system that has only destructive rear-guard actions at hand to stop it. Cut things out; kill it with poison; zap it with radiation. These procedures all leave a body worse for wear, and if they don’t work… they bring you back and do some more of them.

      My great grandfather died while rolling a ball on the lawn bowling green in his late 80s. Massive stroke, he died doing something he loved and was dead before he hit the ground. Floyd Ramsey hit the mortality jackpot.

      Naturally, I would also like to hit that jackpot. Cancer says, “not so fast, you might have a different life experience ahead of you”.

      It would be a little too pat to say that getting a diagnosis starts you off on the stages of grief, because that implies some orderly process to the mental evolution. I am not progressing linearly through the stages of grief, so much as visiting them randomly, over and over, in an emotional shuffle mode.

      Some days are denial days. Some days are acceptance days. Some days are bargaining days.

      Mountain

      I told my councillor last week that “I only feel OK to the extent that I am dissociative”, and that seems to still hold true. I am at my most together when I have fully distracted myself from the diagnosis. I’m not sure if this counts as “taking one day at a time”. Probably not.

    • sur A recap of the 128th OGC Member Meeting, Delft, The Netherlands

      Publié: 17 April 2024, 11:32pm CEST par Simon Chester

      Two records were broken in Delft this March: not only was OGC’s 128th Member Meeting our biggest ever – with over 300 representatives from industry, government, and academia attending in-person (and over 100 virtual) – but the meeting also saw a record number of motions for votes on new Standards, highlighting the very productive activities undertaken by the OGC community in recent months.

      Held in Delft, Netherlands from 25-28 March, 2024, OGC’s 128th Member Meeting brought together global standards leaders and geospatial experts looking to learn about the latest happenings at OGC, advance geospatial standards, and see what’s coming next. Hosted by TU Delft and sponsored by Geonovum with support from GeoCat and digiGO, the overarching theme for the meeting was GeoBIM for the Built Environment.

      As well as the many Standards and Domain Working Group meetings, the 128th Member Meeting also included a Land Administration Special Session, a Geospatial Reporting Indicators ad hoc, a Data Requirements ad hoc, the OGC Europe Forum, an Observational Data Special Session, two Built Environment sessions subtitled The Future of LandInfra and What Urban Digital Twins Mean to OGC, a public GeoBIM Summit, a Quantum Computing ad hoc, and the usual Monday evening reception & networking session and Wednesday night dinner. 

      The dinner was held at the historic Museum Prinsenhof Delft, former residence of William of Orange, and – grimly – where he was assassinated. On a lighter note, during the dinner Ecere Corporation, represented by Jérôme Jacovella-St-Louis, received an OGC Community Impact Award for their tireless work in driving OGC Standards forward. Congratulations Ecere and Jérôme!

      Attendees of the Wednesday night dinner at OGC’s 128th Member Meeting.

      Also during the meeting members of the OGC GeoPose and POI SWGs in collaboration the Open AR Cloud team and XR Masters, and support from Geonovum demonstrated interoperable AR browsers. The two AR browsers (one native app, MyGeoVerse by XR Masters, and spARcl, a WebXR-based browser) were able to share/see the same POIs while being geolocalized using the Augmented City Visual Positioning Service (VPS). The VPS receives requests from (and returns) ‘GeoPoses’ to any OGC-compliant app that has implemented the GeoPose standard. The project details are described on this page and captured in this two minute video on YouTube.

      In tandem with the theme of GeoBIM, two other technology areas stood out during the meetings: Data Spaces, and the transition from OGC Web Services to OGC APIs.

      Data Spaces

      There has lately been a dramatic increase in the number of discussions on Data Spaces, both in and outside of OGC, as the concept becomes more commonplace in European projects and policy. As per the European Union Data Spaces Support Centre, a Data Space is defined as “an infrastructure that enables data transactions between different data ecosystem parties based on the governance framework of that data space.” In other words, the “space” in a Data Space defines a context for which the data are useful: a container, governance, and access. Given the ubiquitous use of geospatial data, directly and indirectly, an understanding of the Data Space ecosystem may be key to participate in emerging data infrastructures.

      OGC Web Services to OGC API transition

      The full set of capabilities offered by the OGC Web Services Standards (e.g., Web Map Service (WMS), Web Feature Service (WFS), etc.) is now reflected in OGC API Standards that have either been published, are approaching final approval vote, or are being actively developed. Over the coming months, OGC will establish a process and resources to aid in the transition to the more modern Standards, while ensuring that the user community recognizes that the legacy web services are still functional and valuable.

      Friso Penninga, CEO of Geonovum, opens the week with an introduction to Geonoum and Delft. Opening Session

      The week opened with a welcome from Friso Penninga, CEO of Geonovum, who outlined not only the work of Geonovum, but also the culture of Delft. Following this, Prof. Jantien Stoter of 3Dgeoinfo, TU Delft highlighted activities at TU Delft in the meeting theme area and previewed Wednesday’s GeoBIM Summit. Pieter van Teeffelen of digiGO then presented a Dutch platform for digital collaboration in the built environment. Finally, Jeroen Ticheler of GeoCat explained challenges in social welfare and the work of the GeoNetwork to address these challenges.

      Next, it was time to settle a long-running dispute in OGC: who has the better chocolate, Switzerland or Belgium? After a blind taste-test, the audience voted Belgium as the winner. Is the debate now settled? Only time – and perhaps our taste buds – shall tell. 

      The chocolate contest was followed by a demonstration of the Netherlands Publieke Dienstverlening Op de Kaart (PDOK) geodata platform, which integrates a number of published and draft OGC API Standards.

      Special tribute was then paid to two instrumental figures in OGC’s history who passed away in November 2023: Jeff de la Beaujardiere (OGC Gardels and Lifetime Achievement Awards recipient) and Jeff Burnett (former OGC Chief Financial Officer).

      Prof. Jantien Stoter of 3Dgeoinfo, TU Delft, offered a preview of Wednesday’s GeoBim Summit during the Opening Session. Today’s Innovation, Tomorrow’s Technology, and Future Directions

      As always, the popular Today’s Innovation, Tomorrow’s Technology, and Future Directions session runs unopposed on the schedule so that all meeting participants can attend. At this Member Meeting, the session was presented by Marie-Françoise Voidrot and Piotr Zaborowski of OGC’s Collaborative Solutions and Innovation Program (COSI). The session focused on several projects that OGC is participating in and are developing capabilities that will be of use to all members. Many of these projects are sponsored by the European Union to advance interoperable science and data management and are supporting OGC resources such as the OGC RAINBOW registry, GeoBIM integration, and learning and developer resources, such as the Location Innovation Academy.
      OGC Members can access the presentations and a recording from the session on this page in the OGC Portal. An overview of some of the European projects highlighted during the session, entitled European Innovation, Global Impact, was published on the OGC Blog last year.

      Piotr Zaborowski, Senior Director, of OGC’s Collaborative Solutions and Innovation Program, presents some of the European Union funded projects in which OGC is involved. Meeting Special Sessions

      The Land Administration Special Session was dedicated to updating OGC membership on the progress of Land Administration activities amongst members and in ISO/TC 211, where the Land Administration Domain Model (LADM) is managed. A new Land Administration Domain Model Standards Working Group (SWG) is being considered to create Part 6 of LADM: the encoding of Parts 1-5 in one or more formats. OGC Members can access the presentations and a recording here (Session 1) and here (Session 2) in the OGC Portal.

      Geospatial Reporting Indicators have been discussed in the OGC Climate Resilience Domain Working Group (DWG) in the context of Land Degradation. However, the means to exchange indicator information reporting the degree of land degradation (or influencing factors) is not standardized in the community. OGC members are therefore proposing a new SWG to develop such standardized reporting indicators, possibly as extended functionality of work in Analysis Ready Data (ARD). OGC Members can access the presentations and a recording on this page in the OGC Portal.

      An ad hoc session on Geospatial Data Requirements was held to assess the chartering of a new SWG. The purpose of this proposed SWG is to develop a Standard for describing what geospatial data a project or task needs to collect, store, analyze, and present to achieve the project objectives. OGC Members can access the presentations and a recording on this page in the OGC Portal.

      The OGC Europe Forum met on Tuesday with presentations focused on Data Spaces: understanding the European Commission principles of data spaces and how OGC members can engage in the topic. The Forum featured speakers from the International Data Spaces Association (IDSA), ISO/TC211, and the European Commission’s Joint Research Centre (JRC) as well as an open panel discussion. OGC Members can access the presentations and a recording on this page in the OGC Portal.

      Peter van Oosterom, from TU Delft and the co-chair of the OGC Land Administration DWG, presents during the Land Administration Special Session.

      The Observational Data Special Session was organized to identify the various OGC Working Groups that are building Standards or assessing the collection & use of observational data. The session clarified the commonalities between these WGs so they can be considered in future development of observational data Standards. OGC Members can access the presentations and a recording on this page in the OGC Portal.

      Two sessions were held to discuss and prioritize the next steps for OGC activities concerning standardization in the Built Environment. The first of these sessions focused on the future development of the LandInfra suite of Standards: whether priority should be made on new encodings, new Parts, or other tasks. OGC Members can access the presentations and a recording on this page in the OGC Portal.

      The second Built Environment session considered the topic of what Urban Digital Twins mean to OGC. Presentations on human engagement as sensors and the place for digital twins in data spaces were followed by a preview of the OGC Urban Digital Twins Discussion Paper and a panel of OGC specialists to discuss where Urban Digital Twins are most important in OGC. OGC Members can access the presentations and a recording on this page in the OGC Portal. 

      The public GeoBIM Summit emphasized the theme of this meeting: there is a great amount of continuity between the geospatial and Building Information Modeling (BIM) communities and their respective technologies and practices. Numerous rapid presentations highlighted activities using OGC and BIM Standards and use-cases for interoperability. OGC Members can access the presentations and a recording on this page in the OGC Portal. Presentations and recordings will soon be made available to the public on the GeoBIM Summit event page.

      The Quantum Computing ad hoc session included open discussion from OGC Members working with or researching the application of quantum computing technology on geospatial issues. Future ad hoc meetings are planned to move towards the development of an OGC Quantum Computing Working Group.

      Closing Plenary

      The Closing Plenary normally includes two sessions: an open discussion of Important Things suggested by members, followed by motions, votes, and presentations from members to advance the work of the Consortium. However, with the Member Meeting being compressed down to four days (as Friday was a regional holiday) the Important Things discussion was not held. As such, I opened the Closing Plenary with a rapid, 7-minute summary of the entire meeting week, which included Slides and content from a large number of the week’s Working Group sessions, available to OGC Members on this page in the OGC Portal. The Closing Plenary included a record number of motions for votes on new Standards, highlighting the very productive activities of OGC members in recent months.

      Thank you

      Our 128th Member Meeting was our biggest yet. As always, it’s a pleasure to see hundreds of OGC Members get together to discuss, collaborate, and drive technology and standards development forward. Once again, a sincere thank you to our members for investing their time and energy, as well as their dedication to making OGC the world’s leading and most comprehensive community of location experts.

      Publié: 16 April 2024, 2:00am CEST

      A common refrain on my Facebook cancer support groups is that the first months after diagnosis can be among the most stressful. You know the least about the actual extent of your condition, but you simultaneously know for sure that your life is going to change a great deal, starting now.

      It is also the first time for grieving.

      In the worst case it is grieving actual mortality, the very real threat of the end. But even in a relatively low impact diagnosis like my (current) one, there is grief. It is the grief of lost futures, lost plans, lost self-image.

      I am a person who runs and climbs and rows and goes on long walks and travels and teaches and speaks publicly. At least, I was. If all goes according to plan, there will eventually be a new me, who does some or many of those things. Maybe not all of them anymore, there is no predictability or control.

      Last Christmas I took my family to Rome over the holidays. “No time like the present!” I said, little knowing how apt that would be. I’m glad for everything I have done with my family. Climbing mountains, scaling cliffs, travelling afar, and even the predictable summer trips to the beach.

      Some of these adventures were quite hard, and in the moment I wondered to myself “what the heck were you thinking?” In the end, I regretted none of it, and we all have lifelong memories we share.

      Before she was killed by cancer, Amy Ettinger wrote:

      I’ve always tried to say yes to the voice that tells me I should go out and do something now, even when that decision seems wildly impractical … Money always comes back, but if you miss out on an experience, the opportunity may never come back.

      I am trying to pack as much climbing, and eating out, and walks to the cafe, and evening date nights into my life as I can, before the start of treatment. It’s too late for anything big, but these are little things that bring me joy that may become harder to do, after.

      My surgery date is set now, and the procedure will mark an abrupt decline and then the start of a long slow climb back up to whatever “new normal” my body can fashion from my reconfigured plumbing. Some people have great results, some people have terrible ones.

      As always, there’s no way to know, the grey area is omnipresent, which is perhaps why I sound so morose.

      The first quarter of my season has been challenging. I've had to deal with injuries and other niggles, and I'm just starting to feel better when I run. Moving forward on fitness while not being able to run very much has been an interesting problem to work on.

      As I mentioned in Preason running I started my 8 week block of interval workouts with nagging knee pain. This pain continued for 6 weeks. I dealt with it by alternating outdoor runs with low-impact sessions on an elliptical or stair-stepper machine. I did one outdoor session of hill intervals and one indoor session of stair-stepper intervals every week. By the end of the block, I was doing 36 minutes of hard uphill running, and 4 hours of easier running or stepping in a week. It's not where I want to be. At least I didn't have to skimp on the hard intervals. I'm satisfied with doing as much hard running as my knee allowed, and enjoy feeling more fit.

      At the end of last year, I was determined to get some physical therapy and rehabilitate my ankles and feet. I've been visiting a local clinic once a month and have been diligent about doing the recommended exercises. The therapist says that I have good range of motion in my ankles, though there is an imbalance; my right ankle has excellent mobility while the left is only better than average. My bigger problem, in the therapist's view, was that my toes and feet are weak. I needed to build muscle so that I can do toe stands easily and lift my arches. So, I've been going to the gym to build muscle three times a week. I do sets of back squats (5 x 5) for overall strength, and then do sets (3 x 10) of single-leg calf raises on a step with a kettlebell, single-leg squats with toe taps using a barbell and band around my thighs, and single-leg deadlifts with dumbbells. The Three Amigos, as I've been calling these single-leg exercises, have been working for me. My feet and lower legs are stronger and their imbalances are getting ironed out. I feel almost equally good with the deadlifts now, wobbling just one time out of ten, at most, on my left leg. The therapist has me progressing to single-leg jumping now, and I'm feeling better balance with the new exercises, too.

      Consistent strength training, conservative running, and changing the way I sit at work seem to have let my knee recover. I'm standing, sitting on a stool, and reclining more when I work, using a conventional office chair less, and at maximum height when I do.

      A radiology visit in December revealed that I'm developing a bone spur on my right heel. I wonder if this is yet another symptom of imbalance in my feet and legs, more stress on my right foot caused by favoring my weaker left? I'm getting some consultation on this and meanwhile am icing regularly. Two weeks ago I had to stop running for 3 days to treat aggravation of my right sciatic nerve. It was a good reminder to be more diligent about stretching and foam rolling. Otherwise, I'm doing pretty well. Heart palpitations are behind me. I'm eating and sleeping well, keeping sinus infections at bay, and enjoying longer days and generally nice spring weather.

      I'm grateful to be able to continue training and am looking forward to a productive block of tempo running.

    • sur Paul Ramsey: Cancer 2

      Publié: 14 April 2024, 2:00am CEST

      Before I joined the population of fellow cancer travellers, I had the same simple linear understanding of the “process” that most people do.

      You get diagnosed, you get treatment, it works or it doesn’t.

      What I didn’t appreciate (and this will vary from cancer to cancer, but my experience is with colorectal) is how little certainty there is, and how wide the grey areas are.

      Like, in my previous post, I said I was “diagnosed” with cancer. Which maybe made you think I have it. But that’s not how it works. I had a colonoscopy, and a large polyp was removed, and that polyp was cancerous, and a very small part of it could not be excised. So it’s still in me.

      Do I have cancer? Maybe! I have a probability of having live cancer cells in me that is significantly higher than zero. But not as high as one.

      How bad is what I have? This is also a game of probabilty. Modern technology can shave off the edges of the distribution, but it can’t quite nail it down.

      A computed tomography (CT) scan didn’t show any other tumors in my body, so that means I probably don’t have “stage 4” (modulo the resolution of the scan), which is mostly incurable (though it can be manageable), where the cancer has managed to spread outside the colon.

      An MRI didn’t show any swollen lymph nodes, which means I maybe do not have “stage 3”, which requires chemotherapy, because the cancer has partially escaped the colon. But MRI results are better at proving rather than disproving nodal involvement and people report having surgical results that run counter to the MRI all the time.

      That leaves me (theoretically) at “stage 2”, looking at a surgical “cure” that involves removing the majority of my rectum and a bunch of lymph nodes. At that point (after the major life-altering surgery!) the excised bits are sent to a pathologist, and the probability tree narrows a little more. Either the pathologist finds cancer in the nodes (MRI was wrong), and I am “upstaged” to stage 3 and sent to chemotherapy, or she doesn’t and I remain a stage 2 and move to a program of monitoring.

      In an exciting third possibility, the pathologist finds no cancer in the lymph nodes or the rectum, which means I will have had major life-altering surgery to remove… nothing dangerous. My surgeon says I should find this a happy result (no cancer!) which is probably because he’s seen so many unhappy results, but it’s a major surgery with life-long side effects and I would do almost anything to not have to have it.

      Amazingly, despite our modern technology there’s just no way to know for sure if there are still live cancer cells in me short of taking the affected bits out and doing the pathology. Or waiting to see if something grows back, which is to flirt with a much worse prognosis.

      Monitoring will be regular blood tests, annual scans and colonoscopies for several years, as the probability of recurrence slowly and asymptotically moves toward (but never quite arrives at) zero. And all those tests and procedures have their own error rates and blind spots.

      There are no certainties. All the measuring and cutting and chemicals, and I will still have not driven the cancer entirely out, it will stubbornly remain as a probability, a non-zero ghost haunting me every year of the rest of my hopefully long life.

      And of course worth mentioning, I am getting the snack-sized, easy-mode version of this experience! People in stage three or stage four face a probability tree with a lot more “and then you probably die in a few years” branches, and the same continuous reevaluation of that tree, with each new procedure and scan, each new discovery of progression or remission.

      Talk to you again soon, inshalla.

      In 2024 the specter of military conflicts haunts the world.

It should be a matter of extreme shame that there are so many organizations who feel the need to publish interactive maps dedicated to tracking the progress of military action around the globe.

    • sur Paul Ramsey: Cancer 1

      Publié: 10 April 2024, 6:00pm CEST

      A little over a month ago, three days after my 53rd birthday, I received a diagnosis of rectal cancer. Happy birthday to me.

      Since then, I have been wrestling with how public to be about it. I have a sense that writing is good for me. But it also keeps like milk. I wrote most of this a couple weeks ago and my head space has already evolved.

      So writing like this is mostly a work of self-absorption (I’m sure you can forgive me) but hopefully it also helps to raise awareness amongst the cohort of people who might know me or read this.

      Colorectal cancer rates are going up, and the expected age of occurance is going down. Please get screened. No matter your age, ask your clinician for a “FIT test”. If you’re over 45, just ask for a colonoscopy, the FIT test isn’t perfect.

      I have a pretty good prognosis, mostly because my case was caught by screening, not by experiencing symptoms bad enough to warrant a trip to the doctor. Most of the people who get diagnosed after showing symptoms have it worse than I, and will have a longer, harder road to recovery. Get screened.

      Our language of cancer borrows a bit from the language of contagion. I “got” cancer. It’s not quite a neutral description, there’s a hint of agency in there, maybe I did something wrong? This article drives me crazy, the author “went vegan and became a distance runner” after his father died of colorectal cancer.

      Sorry friend, cancer is not something you “get”, and it’s not something you can opt out of with clean living. It’s something that happens to you. Take it from this running, cycling, ocean rowing, rock climbing, healthy eater – driving down the marginal probability of cancer (and heart disease (and depression (and more))) with exercise and diet is its own reward, but you are not in control. When cancer wants you, it will come for you.

      Carefree Climbing

      This is why you should get screened (right?). It’s the one way to proactively protect yourself. The amazing thing about a colonoscopy is, not only can it detect cancer, but it also prevent it, by removing pre-cancerous polyps. It’s possible that screening could have prevented my case, if I had been screened a few years earlier.

      I am now a denizen of numerous Facebook fora for fellow travellers along this life path, and one of the posts last week asked “what do you think cancer taught you”? I am a little too early on the path to write an answer myself, but one woman’s answer struck me.

      She said it taught her that control is an illusion.

      Before, I had plans. I could tell you I was going to go places, and do things, and when I was going to do them, next month, next season, next year. I was in control. Now, I can tell you what I will be doing next week. Perhaps. The rest is in other hands than mine.

      Talk to you again soon, inshalla.

As cities grow rivers can become obstacles to the movement of people, can be seen as wasted real-estate, and historically (when cities had poor sanitation) they often became open sewers.

      Cloud-optimized formats are changing how we handle geospatial data, making it easier to access and work with large datasets directly in the cloud. These formats reduce the need to download entire datasets, facilitating quicker and more focused data analysis and visualization. For those interested in the specifics of these advancements, our recent Cloud Optimized Geospatial Formats – Status Report, offers an introduction into the topic, recommendations for usage and an overview of promising formats.

      Within this project, we also released a sample of various tiles downloaded from swissSURFACE3D as a single cloud optimized point cloud file and made it accessible also via a potree powered web viewer that demonstrates how one single file can be used for visualization in the web and making accessible for applications like QGIS and QField via the direct access URL .

      I would like to thank GeoStandards.ch and SGS to allow us working on this.

      We’re keen to hear from you as well. Please share your experiences or additional insights and formats in the comments.
