FOSS4G-NA in Minneapolis May 22-24

The details of FOSS4G North America have been announced­. Everything is there, from registration, the call for presentations, the gala and the code sprint.

Amongst the keynotes they propose: "Eric Gundersen, CEO, MapBox.  With big names converting from Google Maps to MapBox (USA Today, Foursquare, etc.), Eric will be discussing the business proposition/value of open source geo.

Erek Dyskant, Sr. Analytics Engineer, Democratic National Committee. Whether you were happy or sad with the outcome of the recent election, they must have done something right!  Erek will talk about how open source solutions were used to empower tacticians with geospatial data, and describe what drove the intentional choice of using open source."

Last year, Slashgeo had the chance to be a media partner of the first FOSS4G-NA.

OpenStreetMap: 1 Million Contributors!, Introducing OSM’s New JavaScript Editor, and OSM Editions of Year

Every frequent Slashgeo reader knows about OpenStreetMap, and now, the project reached another important milestone: 1 million OpenStreetMappers.

From the blog entry: "OpenStreetMap has just passed 1 million users! That's a million people who have signed up on openstreetmap to join in with creating a free map of the world. At first glance you may think that OpenStreetMap is a map. Those who know more will tell you that it's actually a database; a flexible editable repository of free geospatial data. But above all OpenStreetMap is a community. A massive community in which people like you and me come together collaborate and help build this thing... and now there's a million of us!"

To ease contributions even more, they also introduced the alpha version of the new OpenStreetMap editor, codenamed iD (screenshot below). And for its beauty, see the short animation on OpenStreetMap: A Year of Edits.

Avenza Geographic Imager Adds Write Support For LizardTech MrSID Format

- MrSID export ability available with Geographic Imager 4.1 -

Toronto, ON, January 7, - Avenza Systems Inc., producers of MAPublisher® cartographic software for Adobe Illustrator® and PDF Maps for Apple iOS and LizardTech, a provider of software solutions for managing and distributing geospatial content, today announced the integration of LizardTech® GeoExpress® 8.5 and the ability to produce MrSID format files into the latest release of Geographic Imager 4.1 for Adobe Photoshop.

LizardTech, based in Seattle, WA, specializes in developing the MrSID format, which handles high-resolution geospatial data. Previous versions of Geographic Imager have already provided read capability for raster and LiDAR MrSID via the integration of LizardTech MG4 Decode Software Development Kit (DSDK). With the current release, Avenza customers can take advantage of the ability to write to MrSID format directly from Adobe Photoshop provided they have the current version of LizardTech GeoExpress installed. This ability expands the number of supported file formats Geographic Imager can write and increases workflow options when working with high-resolution imagery.

“As the leading GIS vendor to support both viewing and writing of MrSID files in Adobe Photoshop, we're excited at the opportunity to partner with LizardTech to provide our users with access to MrSID technology,” said Ted Florence, President of Avenza. “With this integration, customers on both sides will be able to use MrSID images with the entire Geographic Imager toolset without compromise. The capability of tools in Geographic Imager and Adobe Photoshop with the ability to export to MrSID format is an invaluable workflow and shows how committed we are at bringing formats to the platform that may have never been thought possible.” he added.

Jon Skiffington, director of product management at LizardTech, notes, “We're thrilled at the opportunity to work with Avenza Systems to expand the reach of MrSID technology into viable platforms like Geographic Imager for Adobe Photoshop for the benefit of our mutual users.” Additionally, Jeff Young, business development manager at LizardTech, commented, “Collaboration with Avenza allows for more effective support of the Avenza/LizardTech world-wide user community with smoother workflows and more transparent data exchanges.

  • better support for chaining rendering transformations
  • fixes to time/date handling in CQL
  • Oracle specific SDO_NN function to find the N nearest objects to a given location

About GeoTools 8.5

This is a bug fix release containing a number of fixes and improvements, including:

  • several fixes to rendering transformations allowing several transformations to be chained together  in the same rendering request (e.g., interpolate values from discrete points and then also extract isolines from it)
  • fixes to date/time handling in CQL
  • spotted and fixed a deadlock in the rendering subsystem happening if the renderer gets abruptly stopped while working against a very fast data source (or a very slow Graphics2D implementation)
  • a new PullParser class allowing for better streaming parsing of large amounts of XML (e.g., GML, KML)
  • better handling of raster "no data" during reprojection, avoiding border artifacts in the results
  • a new Oracle specific filter function exposing Oracle spatials's K nearest neighbor search

Full details are available in Jira's release notes.

How to Keep Up With Changing Web Mapping Technology

Directions Mag offers an article named Research Explores How to Keep Up With Changing Web Mapping Technology, starting with 'change is inevitable: deal with it'.

From the results: "Despite the fact that the Google Maps API delivered on more of the requirements set out in the Needs Assessment Survey, the team selected Leaflet as the answer to the first question of which technology should be used for teaching. Leaflet was, in fact, second best in supporting the requirements, but the Diary Study suggested students made more progress and felt better working with that set of libraries. The team suggests that might be due to the added transparency and control provided by a fully open source library."

Geopaparazzi 3.4.0 is out! Please welcome the Spatialite brothers… and NFC support

Geopaparazzi 3.4.0 has just been released to the android market. This version has one major feature: support for vector data from Spatialite databases. This opens up a new world for android based mobile devices. This is how it looks like when one uses it by overlaying a scanned Finnish orienteering map and the results of some  hydrologic/hydraulic analyses: old, new and extracted watershed boundaries and channel lines.

Well, the other major feature added to the release gets a bit in the shadow of Spatialite, but it might be even more important to some users: RFID tag reading in custom forms through NFC or bluetooth.

SpatiaLite 4.0 Released

Via Ecostudies I learned that SpatiaLite 4.0.0 has just been released.

Here's the warning and relevant changes related to switching to 4.0: "SpatiaLite Version 4.0.0 introduces several relevant changes; many of these may potentially pose severe cross-version compatibility issues. Accordingly to the above premise, a good comprehension of any related detail will surely allow you to successfully master and resolve any transition issue." A reminder, "SpatiaLite is an open source library intended to extend the SQLite core to support fully fledged Spatial SQL capabilities. SQLite is intrinsically simple and lightweight [...]"

See also this related discussion (read the comments) on SpatiaLite, the Shapefile of the Future? Of course, we mentioned SpatiaLite several other times.
