sur Geospatial air du temps by Géo212

Dans les sorties du début d'année, quelques livres entrent en résonance avec nos passions.

On commencera par La disparition de Paris et sa renaissance en Afrique. Non, on ne parle pas du cauchemar des duettistes Frédéric Lefèvre et de Georges Frèche (quoique ...) mais du dernier roman de Martin Page (Editions de l'Olivier).

Comme toujours chez Martin Page, le lecteur fait avec bonheur le grand écart entre une écriture précise et réaliste et des histoires incroyables (quoique ...). Comment le narrateur va honorer sa promesse faite à une vieille femme quand la demande consiste à faire disparaitre Paris ?

On poursuivra avec Bakou, derniers jours d'Olivier Rolin (Fiction & Cie/Seuil). On n'est pas toujours très fan d'un gars qui se la pète un peu trop "nouveau Malraux", mais si on oublie le côté "moi, je", il y a dans la description de l'Azerbaidjan actuel des choses passionnantes qui laisseraient même imaginer qu'Olivier Rolin n'est peut être pas le grand écrivain qu'il croit, mais qu'il ferait un remarquable géographe.

On terminera avec Macau d'Antoine Volodine (le texte) et Olivier Aubert (les photos) également chez Fiction & Cie. Volodine avait déjà écrit sur Macau (Le Port intérieur aux Editions de Minuit en 1995) et il réutilise le personnage de Breughel. Comme toujours chez Volodine, l'écriture est très simple.

"Le Livre des Morts avertit le mort qu'il sera seul, et que, au moins là-dessus, il ne devra pas se bercer d'illusions. Mais toi, tu seras encore vivant, et les instructions au cadavre ne te concerneront pas encore. Rien ne sera là pour te dire ce qu'il faut faire. Tu seras en face de toi même, allongé sur le sol, épuisé, et tu écouteras mollement les bruits provenant d'une cuisine voisine, et, n'ayant pas d'instructions pour affronter ta solitude, tu regarderas le ciel de plomb derrière la fenêtre et tu regretteras le temps où tu pensais que mourir serait plus simple."

Les photos noir et blanc d'Olivier Aubert forment un contrepoint remarquable au texte.

Friday’s Food for Thought: Don’t Call Me; Text Me Instead Because I’m “Going Mobile”got geoint?
sur Planet Geospatial - http://planetgs.com

Welcome to the Friday’s Food for Thought post on got geoint? Do you ever get the feeling that people no longer actually speak to one another? We like to stay within the safe bubble of email and texting as a primary communications vehicle. And do you remember Jerry Seinfield’s classic stand up joke about being surprised when someone actually answers his or her phone – as opposed to the call going to voicemail. So, where are we going with this? The big GEOINT story we covered this week was regarding war fighters using innovative smart phones. We could not help but think that mobile/digital communications is finally everywhere.

History of Texting

Remember about 10 years ago, how everyone in Japan and parts of Europe were texting each other? We often wondered if this phenomena was going to catch on here in the U.S. And of course it did – in a major way. Well, SMS was first used in December 1992, when Neil Papworth, a 22-year-old test engineer for Sema Group (now Airwide Solutions), used a personal computer to send the text message “Merry Christmas” via the Vodafone network to the phone of Richard Jarvis. Bet you did not know that…check out more on the history of texting from our friends at Wikipedia here.

Need to Call The Office? Where’s The Nearest Pay Phone?

Remember the days when the only way to call into the office was to find the nearest pay phone? You would wait in line at the airport – other harried executives in competition for these coveted phones – just to call in and get all of your voice messages. Then it was a game of phone tag when getting back to people. Amazing that we actually got anything done. Well, here’s a story about a pay phone in NYC that still gets plenty of attention.

Future of Texting and Mobile Communications

So, we all have our PDAs, iPhones and Blackberrys always within reach. So, where do we go from here? Will we always be carrying around these little black, rectangular communications objects in our hands forever? Or will our physical bodies merge (literally) with the technology as many futurist would like to believe? Or will it be voice-activated texting that will transcribe what you say into text? Wait, doesn’t that sound like talking? Perhaps the future will be more vocal communications amongst each other? Now, that would be something!

The Who’s “Going Mobile”

Man, we all knew Pete Townsend was a visionary songwriter. But, did he have his hand on the crystal ball, or what, when he wrote “Going Mobile” in 1971? Here’s the actual track (via YouTube). Enjoy and happy Friday!

Geotag Photos with an Android Phone and Any Digital CameraGreetings from Manasquan, NJ
sur Planet Geospatial - http://planetgs.com

There are many ways to add geospatial information to photos, whether you use Flickr or Picasa's Heads-Up Digitizing Tools, or an expensive camera with a built-in GPS, a camera phone that has a built in GPS, or a GPS Data Logger and a standard Digital Camera. However, I wanted to share a way I use an Android Smartphone (Motorola Droid) and a standard point-and-shoot Digital Camera (Canon SD780 IS) together in a hybrid approach to automatic geotagging.

This approach lets me cut down on the devices I need to carry along with me (don't need to carry a GPS data logger anymore), and lets me shoot higher resolution images than the 5MP camera on the Droid would allow.

The Tools You'll Need:

Android Apps:

My Tracks for Android:

GPS Test for Android:Linux / Mac / PC App:

gpicsync: Follow the instructions for installing on your OS.

Step 1. Start Logging:

Launch My Tracks and from the context menu choose "Record Track," this will start the My Tracks data logger.

You'll need to keep your phone out (screen can turn off) for the duration of your picture taking - My Tracks will record your track.

Step 2. Launch GPS Test:

As with using a stand-alone GPS, you need to take a temporal reference photo to figure out the time difference between the GPS system (in which your log file will be recorded) and the camera time (which will be timestamped in each image).

To take this image, use the free app GPS Test to display the current GPS time in the UTC time zone.

Step 3. Set Your Camera's Time:

My camera has a home / away function so I can set my home time zone but also an "away" time zone - in this case my "away" time zone will be UTC time. Your camera may vary, but try to set the time as closely as possible to the UTC time shown in the time screen of GPS Test.

Step 4. Take a Picture of Your Phone:

From the Time screen in GPS Test, take a photo of your phone's screen with your camera - this picture will serve as your temporal reference in gpicsync so you can investigate the time difference between the GPS and your camera when you go to sync the photos to the GPS track.

Step 5. Keep You Phone Out, Take Pictures:

Your phone can probably stay in your pocket, but it needs a view of the GPS constellation to record your track well.

Step 6. When Finished Shooting, Stop Recording Your Track:

Use the context menu in My Tracks to select "Stop Recording".

You should have a nice map that shows you the track you collected.

Step 7. Send Yourself Your Track:

Use the "Share With Friends" feature of My Tracks to e-mail yourself a "GPX" version of your track, you will use this file as your track in gpicsync.

Step 8. Launch gpicsync, Fix Time:

The first thing you need to do is to set up the time correction, from the Options menu choose "Local Time Correction"

Open the temporal reference image in a program like Google's Picasa, or just Windows Explorer or Mac OSX's Finder to simultaneously see the timestamp (camera date) of the image and the time that is shown by GPS Test for the UTC time.

Enter these values into the Local Time Correction Dialog.

Step 9. Select Your GPX Track and Photo Directory

For the "Pictures Folder," select the directory on your computer where you have downloaded the photos you want to be automatically geotagged in the gpicsync application.

For the "GPS File," select the GPX file that you previously e-mailed yourself.

Click "Synchronize" and gpicsync will index the times in the GPX file and then for each image in the directory check the timestamp of that image against the index to see where you were when that photo was taken and automatically will update the image's EXIF Header to include a GPS position.

When finished, you will have a directory of automatically geotagged photos, a backup of the original photos, and even a KML file that you can open and view your photos spatially in Google Earth.

Or, you can just upload the photos to a site like Flickr or Picasa and the website will automatically read the EXIF Headers and will store your photos as geotagged photos online.

Check out an example of a recent Helicopter tour I took with my parents and the geotagged photos I took using this method here.

Mapbender Team: Report from the Mapbender Code Sprint at FOSSGIS 2010
sur Planet OSGeo

The fourth day of the FOSSGIS 2010 conference in Osnabrück, Germany (Friday 5th of March) saw a day of Mapbender hacking. A dozen developers and power users flocked around Mapbender to discuss general issues and hack a bit. The agenda (link) listed several points we wanted to address explicitly.

One important question was the next release. The last year has seen massive refactoring and a lot of new functionality and finally Mapbender ships with an install script. But a lot of old modules, especially quick & dirty hacks broke during the refactoring. The more generically focused developers favor a clear cut and to remove old stuff. The more user-implementation focused developers favor a slower approach and keeping the broad set of functionality, even if it means to carry along old stuff. Many Mapbender installations are long lived and typically host metadata for hundreds and thousands of services and users who need the web mapping platform in every day work. This puts a lot of responsibility on the development group to create stable software and smooth upgrade paths. Therefore it was decided to release a bug fixed version 2.6.1 next week.

One important goal of latest development has been the leverage of jQuery and jQuery UI to pimp the Mapbender front end. Adopting jQuery and being able to include tons of PlugIns make Mapbender look and feel a lot more up-to-date and addresses the user's desire for sleeker user interfaces. Another very important improvement that came out of the refactoring efforts is much cleaner code which will make it a lot easier for new developers to get into Mapbender.

Therfore it was decided to step up a full version number in summer with new features and most importantly a clean and well documented API. A full version step also justifies that some older installations will brake at some points. This is an invigorating decision as it will allow us to be cleaner and meaner with old stuff. The new Mapbender API will make developing much easier and more fun in.

The first release candidate 3.0 will come out after the Bolsena hack sprint. It will include a thorough integration of OpenLayers, a completely refactored user interface and potentially even a connection to a metadata bucket with thousands of OGC services to choose from. But that is another story.

Have fun.

I think this video from Penn State University's Geospatial Revolution project does a tremendous job in explaining the power of geospatial technology as well as its growing role in our society. (I know that I am going to start showing it to friends and family who ask me to explain spatial technology). However, I think it also very useful in pointing the number of legal and policy issues that are developing because of the increased importance of the technology.

Paul Ramsey: Send us Jeremy and Keyur!
sur Planet OSGeo

ESRI (pretty new web page, by the way) has put their open source position on-line and also produced a short podcast with Victoria Kouyoumjian on the same topic.

[www.esri.com]

One thing that struck me in the podcast was when Victoria noted that ESRI has sponsored open source events in the past (most notably FOSS4G 2007 directly, but also 2008 and 2009 to a lesser extent through 50°North). She says,
These events allow us the opportunity to engage in conversations and dialogs with various technologists because we want to gain feedback about the needs of open source developers and users. The objective of course is to channel this information back to development so we can reflect this in future products and business decisions in order to best support our customers.
So far ESRI attendance has been at the managerial level, and while I love those guys (hugs to Satish and Victoria!) some real sparks could fly and serious interoperability improvements be made if we started seeing the developers, the project leads and software designers, at the events. We can do better than "channeling" information back to development, let's immerse development in it!

Update: We promise to send them back. Really.

Using GeoServer, Openlayers, and CQL FiltersFuzzy Tolerance

sur Planet Geospatial - http://planetgs.com

I received a request this week to put Census Questionnaire Centers (QAC) on a web app ASAP. In case you don’t follow the Census’ every move:

Questionnaire Assistance Centers (QACs) are spaces, donated by community partners, where staff from the Local Census Office or the partner organization are available to answer questions about completing the questionnaire, provide special language assistance and answer general questions.

This is a short term thing – the QACs are only open for 4 weeks or so – and the only initial requirement was dumping the points on the map and showing information when you click on them. So I dumped the shape file into Postgres, published the layer with GeoServer, and added it to an app as a vector layer (KML).

For the most part this code was proudly pilfered from one of the OpenLayers samples. Here we’ll add the layer to the map and set some select events. I made the census_qac_layers a global variable so I could get at it later. Note I took out the enormous URL so the page wouldn’t explode, but this was it (it will probably ask you to pull it up in Google Earth).

// QAC Centers for Census
    census_qac_centers = new OpenLayers.Layer.Vector("Census QAC Centers", {
        projection: map.displayProjection,
        strategies: [new OpenLayers.Strategy.Fixed()],
        protocol: new OpenLayers.Protocol [HTTP({]             url: "http://enormous-url",
            format: new OpenLayers.Format.KML({
                extractStyles: true,
                extractAttributes: true
            })
        })
    });
    census_qac_centers.setVisibility(false);
    map.addLayer(census_qac_centers);
    select = new OpenLayers.Control.SelectFeature(census_qac_centers);
    census_qac_centers.events.on({
        "featureselected": onFeatureSelect,
        "featureunselected": onFeatureUnselect,
        "stopClick": true
    });
    map.addControl(select);
    select.activate();

And here are the onFeatureSelect and onFeatureUnselect functions we referenced. They’ll handle creating the popups.

/* Functions for Census QAC Centers */
    function onPopupClose(evt) {
            select.unselectAll();
        }
        function onFeatureSelect(event) {
            var feature = event.feature;
            // Since KML is user-generated, do naive protection against
            // Javascript.
            var content = ""+feature.attributes.name + "" + feature.attributes.description;
            if (content.search("" + content.replace(/
Done and done. Our map now has the pox, and each pustule will pop up the QAC information. I gave the KML output a little styling, which is literally as simple as dropping a couple of files like this in your layer folder (here’s description.ftl):
${partner_na.value} 

${street.value} 

${phone.value} 

Hours: ${hours.value} 



Langauges served: ${language_s.value}

Being at least nominally an agile guy, I (a) release early and often and (b) fully expect changes. So we tossed it out there, looked at it, and decided it didn’t make sense to show all the QAC’s at once. What people would really want to do is show just the locations that support their language. I don’t want to click through 111 locations hunting for a QAC that supports Hindi.
The last thing I wanted to do was make a bunch of separate layers/views/styles for different languages, and an individual QAC can support multiple languages, further complicating the matter. 
CQL to the rescue.
CQL, the Contextual Query Language, is a formal language for representing queries to information retrieval systems such as web indexes, bibliographic catalogs and museum collection information. The design objective is that queries be human readable and writable, and that the language be intuitive while maintaining the expressiveness of more complex languages.
CQL was developed by the Library of Congress and OGC used it as a basis for its filter encoding spec (I *think*). GeoServer fully supports the OGC filter encoding sped, but sending it over HTML makes for a horrid mess, as you writing and URL encoding XML. GeoServer also supports plain old CQL, which is quite a bit easier. I needed to add a line to the layer declaration to hold a CQL_Filter parameter.
// QAC Centers for Census
    census_qac_centers = new OpenLayers.Layer.Vector("Census QAC Centers", {
        projection: map.displayProjection,
        strategies: [new OpenLayers.Strategy.Fixed()],
        protocol: new OpenLayers.Protocol [HTTP({]             url: "http://enormous-url",
            'params' : { 'CQL_FILTER' : ''},
            format: new OpenLayers.Format.KML({
                extractStyles: true,
                extractAttributes: true
            })
        })
    });

Next I made a standard HTML radio button list, with the value being the language.
 English

 Arabic

 Chinese

 French


Etc. Now for some jQuery goodness.
    // Census QAC Stuff
    $("input[name='qac_centers']").attr("checked", false)
    $("input[name='qac_centers']").change(
        function()
        {
            census_qac_centers.setVisibility(true);
            filterval = "language_s like '%" + $("input[name='qac_centers']:checked").val() + "%'";
            census_qac_centers.refresh({
                force: true,
                params: {
                    "CQL_FILTER": filterval
                }
            });
        }
    );

Let’s walk through this. First, we set all the radio buttons to be unchecked (Firefox likes to remember that stuff from session to session). Next we detect whenever a change occurs (i.e. a radio button is checked) and run a function. We set the layer to visible, grab the language value of the checked radio button, and create the CQL filter. It’ll end up looking something like this, where language_s is the field name we’re querying:
language_s like '%Spanish%'

I’m doing a like operation because the field has a comma delimited list of languages it supports. This next bit does the heavy lifting.
census_qac_centers.refresh({
      force: true,
      params: {
                    "CQL_FILTER": filterval
                }
 });

Here we take the CQL_FILTER parameter we added to the layer, and we’re dropping in the CQL we created. The layer is refreshed with the new URL, and only the features that match our CQL filter will come back. A user clicks on German, only the German QAC’s show up.
The CQL Filter option is available on any layer in GeoServer (not just vector), and with the parameter option in OpenLayers it’s very easy to dynamically change the content of a layer. We were able to turn around this request in an extremely short amount of time (a couple of hours, a large portion of which was navel-gazing design) and in a way that’s easy to extract from the application when the QAC’s go away in a month.
You can view it on GeoPortal, second accordion tab on the left.

Congressional Hearings on Location PrivacySpatial Law and Policy
sur Planet Geospatial - http://planetgs.com

There has already been a good deal reported about the recent Congressional hearings regarding the privacy implications associated with the collection and use of location data on mobile devices. It should not be any surprise that Congress is taking a look at this issue, given the growing number of devices and associated consumer applications as well as the potential implications associated with this technology. Nor should it be surprising to hear Representative Rick Boucher state that future legislation will likely include provisions addressing this issue, as Congress been down this road before, including proposed legislation from then Senator John Edwards. In fact, it would probably be prudent for all companies in the U.S. that collect or use customer location data to become familiar with the privacy regimes associated with medical records (HIPAA), consumer credit (Fair Credit Reporting Act) and financial information (Graham -Leach- Bliley Act), as Congress and the Federal Trade Commission appear to have a framework they like to use on privacy matters. It is very likely they will try to apply a similar framework for location data.

Daniel Morissette: ESRI publishes its position on open source software
sur Planet OSGeo

(Version française)

I just found out that ESRI has published an official position on open source software on its website at [esri.com] that sounds quite encouraging. (Thanks to Chaipat Nengcomma's blog post that I could not read but that hinted me to this.)

There is also an interesting podcast where Victoria Kouyoumjian (ESRI IT strategy architect) "discusses ESRI’s position on open source and the importance of open source software in GIS application development" (quoting their own summary).

We already knew that ESRI had been using GDAL for some time, had integrated support for PostGIS in SDE more recently and even sponsored FOSS4G 2007, but to find an official statement of their position is definitely encouraging. I even dare to dream of collaboration between ESRI people and other OSGeo projects in the not too distant future (gotta be optimistic).

I know (for having been through this myself a few years ago) that ESRI has not always had only good words for people who made the choice of open source software for their projects in the past. Let's hope this position is sincere and will propagate across the whole organisation, and that things will really change and lead to a spirit of real collaboration, for the benefit of all the neo-geographers who want the best of both worlds.

ILMF Announces ELMFLiDAR News
sur Planet Geospatial - http://planetgs.com
1. The ILMF conference organizers are launching a new event – ELMF10 this fall in Europe.
2. It will be located in the Hague, Netherlands November 30 and December 1, 2010.
3. The conference will include airborne, bathymetric, mobile and terrestrial.
One of the more interesting announcements from this year’s ILMF LiDAR10 conference came from the organizers. They will be launching a new conference this fall in Europe. Dubbed the ELMF10, for European LiDAR Mapping Forum, this new 2 day technical conference and exhibition will be located in the Hague, Netherlands.

The conference will be held November 30 and December 1, 2010 at the World Forum. The theme will be “LiDAR Across the Market Spectrum”, which will include airborne, bathymetric, mobile and terrestrial. This is a broader reach than the US event.

I believe this will be the first LiDAR conference directed at the European community, and I am sure it will draw from Africa, the Middle East and Asia as well. That could make it more international than the ILMF. Time will tell.

Frank's kite imagery of Petite Tabac is now in Google EarthGoogle Earth Blog
sur Planet Geospatial - http://planetgs.com

Back in January, we showed you the incredible photos that Frank took while visiting the island of Petite Tabac. You might recognize it as one of the islands used in "Pirates of the Caribbean", as seen below:

As part of the imagery update last week, Frank's photos were added to the primary layer in Google Earth!

If you look close (as seen in the image below), you'll see their dinghy ("Coconut") and you can see Frank standing on the beach just east of there!

Here is a KML file to fly you directly to the island so you can see it for yourself.

He also shot a pretty cool 360° panorama while he was there, which you can check out on his blog.

This isn't the first time his photos landed in Google Earth. Last November, some of his other kite imagery also made it into Google Earth.

Les éclairs blancs indiquent les modifications cartographiques pendant les 12 heures qui ont suivies la catastrophe naturelle. Les modifications ont été réalisées à partir d’images satellites et de photos aériennes.
Le principal objectif des mises à jours portait sur la numérisation des routes (route primaire en verte et route secondaire en rouge) puis sur les camps de réfugiés qui émergeaient (en bleu).

Cette réactivité dans la mise à jour de données cartographiques m’impressionne.

GIS-Lab: DPSimplify для QGIS
sur Planet OSGeo

Новое расширение для QGIS. Предназначено для уменьшения количества точек в линейных слоях по алгоритму Дугласа-Пойкера (Douglas-Peuker), с настраиваемым уровнем детализации.

Может работать целиком с линейным слоем, так и с выделенным объектом или объектами. Может как сохранять в новый shape-файл, так и менять прямо в существующем. Расширение было специально разработано для проекта по границам субъектов, где кое-кто слишком усердствовал при оцифровке. Но, конечно оно пригодится и в массе других случаев.

Расширение доступно их репозитория плагинов ГИС-Лаб. Отзывы и багрепорты можно оставлять в специальной теме на форуме или слать по почте.

UPD: Пример на картинке – просто пример и не показывает, как мы будем упрощать результаты проекта. Вопрос будем ли упрощать и как именно обязательно будет выноситься на общее обсуждение.

Its official we will be giving two PostGIS mini-tutorials at PgCon East in Philadelphia late this month (March). Both will be on March 27th, preliminary calendar PostgreSQL Coneference East 2010 March 27th, 2010.

Marcus Rouhani of the FAA will also be talking about Airport GIS and use of PostgreSQL/PostGIS in that project. Interestingly, it looks like he's scheduled to talk on the same day we are.

Other PostGIS events. OSGEO just finished the New York City Sprint, where PostGIS was well represented, but sadly we were not able to make. Our summary of what we could glean from participants blogs (PostGIS highlights) are summarized at What is new in PostGIS.

On yet another note, we managed to scrape up some time to push out our customary cheat sheet guide to PostGIS 1.5. Hopefully we didn't leave out anything critical.

For those interested in buying PostGIS in Action, we have been informed that Manning is planning to have a one day sale 50% discount on all MEAP books this Friday, which in Manning time should be a an hour or so from now. They have a truly great line-up of upcoming books.

Dylan Beaudette: Accessing Climate Change Data and a Custom Panel Function for Filled Polygons
sur Planet OSGeo

GCS Model Grids

Recently finished some collaborative work with Vishal, related to visualizing climate change data for the SEI. This project was funded in part by the California Energy Commission, with additional technical support from the Google Earth Team. One of the final products was an interactive, multi-scale Google Earth application, based on PostGIS, PHP, and R. Interaction with the KMZ application results in several presentations of climate projections, fire risk projections, urban population growth projections, and other related information. Charts are dynamically generated from the PostGIS database, and returned to the web browser. In addition, an [HTTP-based] interface makes it simple to download CSV-formatted data directly from the CEC server. Some of our R code seemed like a good candidate for sharing, so I have posted a complete example below-- illustrating how to access climate projection data from the CEC server, a couple custom functions for fancy lattice graphics, and more.

Yes, that’s right, 137 years of awesome issues of Popular Science magazine are now available online by searching the archive at the PopSci website. If you’re a science or gadget nerd, you’ll have lots of fun checking out the science frontiers of decades gone by, and even checking out the advertising and graphics styles for the original issues.

About the only drawback is that you have to enter a search term to get into the archives, as there is no browse function available so far. However, once you’ve searched on a term, such as “rocket pack”, you can browse around through the whole issue using the archive viewer’s navigation.
