GeoServer 2.4 Released

Another significant release done at FOSS4G 2013 is the open source GeoServer 2.4. Along with MapServer, GeoServer is a popular server to disseminate geospatial data in WMS, and other standards of the same family.

Since I failed to find a nice list of what's new specifically for version 2.4, I feed you with a reminder of what GeoServer is according to their front page: "GeoServer is an open source software server written in Java that allows users to share and edit geospatial data. Designed for interoperability, it publishes data from any major spatial data source using open standards. [...] GeoServer is the reference implementation of the Open Geospatial Consortium (OGC) Web Feature Service (WFS) and Web Coverage Service (WCS) standards, as well as a high performance certified compliant Web Map Service (WMS). GeoServer forms a core component of the Geospatial Web."

QGIS 2.0 Released

This is major news. The popular open source desktop GIS formerly known as Quantum GIS, now simply QGIS, has released its version 2.0 at FOSS4G 2013. This release reduces the gap with some of the mature commercial desktop GIS available. There's also QGIS 2.0 for Android in the works.

Here's the full list of what's new and changed - it's just too long to copy it all, so here's some of it:

User interface:

  • Feature: Side tabs, collapsable groups
  • Feature: Soft notifications
  • Feature: Drag and drop form builder

Data providers:

  • Feature: Oracle Spatial support
  • Feature: Web Coverage Service (WCS) provider added
  • Feature: Raster 2% cumulative cut by default
  • Feature: WMTS Support

Symbology:

  • Feature: Data defined properties
  • Feature: Support for transparency in colour definitions
  • Feature: Color Control for Raster Layers

Map composer:

  • Feature: Multipage support
  • Feature: Layer blending
  • Feature: Multicolumn composer legend

Labeling:

  • Feature: Expression based label properties

There's a lot more to it. Head to the full list to learn more and see numerous screenshots.

geojson.io: Vector Data Edition and Sharing for Everyone

I lied, I have not yet shared all the pertinent geonews that happened during my extended holidays, I was keeping this gem just for myself, here it is! In late July, the open source geojson.oi website for drawing, changing, and sharing GeoJSON-formatted map data was announced by MapBox's Tom MacWright. This is major news in my opinion: creating and sharing basic vector geodata on a map can't be made easier and accessible. Try it out yourself.

Here's the about page. The brief initial announcement: "geojson.io is for drawing, changing, and sharing GeoJSON-formatted map data. Save as a GitHub Gist and share a link. Hit Cmd-S to do it quickly. Edit the JSON properties in GeoJSON features easily. Line-specific JSON-validation errors from jsonlint. Line-specific GeoJSON-validation errors from geojsonhint. Use geojson.io with modern mapping tools, like TileMill, MapBox.js, GitHub, and Shapely. It’s made of open source: Leaflet.draw, MapBox.js, CodeMirror, and a new library I wrote called geojsonhint, that does GeoJSON validation."

TileServer-PHP: OGC Web Map Tiling Server (WMTS)

While we mentioned several times the WMTS OGC standard and its brother the TMS protocol, we never mentioned TileServer-PHP, an open source Web Map Tiling Server.

From the github readme: "This server distributes maps to desktop, web, and mobile applications from a standard Apache+PHP web hosting. It is a free and open-source project implementing OGC WMTS standard for pre-rendered map tiles made with MapTiler Cluster, MapTiler, GDAL2Tiles, or available as MBTiles files. It is the easiest and cheapest way how to serve zoomable maps in a standardized way - practically from any ordinary web hosting. It is easy to install - just copy the project files to a PHP-enabled directory along with your map data containing metadata.json file. It comes with an online interface showing the list of the maps and step-by-step guides for desktop GIS software [...]"

Also important, supported protocols are:

  • OpenGIS WMTS 1.0.0
  • OSGeo TMS 1.0.0
  • TileJSON.js
  • Direct access with XYZ tile requests (to existing tiles in a directory or to .mbtiles)

PostGIS 2.1.0 Released

Still catching up geonews, this is a major one, the mature open source geospatial database PostGIS 2.1.0 has been released.

In short, "This release contains a ton of speed improvements, function additions , and super sexy new features. It has been over a year in the making. New functions itemized here". The highlights:

  • "More terrain analysis functions. In addition so slope and aspect calculations, there are now also roughness, Topographic Position Index and Terrain Ruggedness Index.
  • Tiling large rasters into small rasters with ST_Tile. This is useful for analyses that work best on large rasters, but are served out as results best as small tiles. The raster opposite of ST_Tile is ST_Union, which has received performance improvements in 2.1
  • New geocoding engine. The TIGER geocoder that has shipped with PostGIS for several years has been enhanced using the address normalization engine from PACG. As a result, batch geocoding is an order of magnitude faster.
  • New selectivity calculations, supporting N-D and geographic indexes, as well as improved join selectivity calculations. Will provide generally improved query planning for complex SQL.
  • Performance enhancement by up to 20x for ST_Distance calculations on geography.
  • Delaunay triangulation inside the database with ST_DelaunayTriangles.
  • Performance and functionality enhancements to ST_MapAlgebra, allowing even more crazy in-database raster analytics."

Fiona 1.0 Released: Python OGR API

While we mentioned the Fiona a few times since 2011, with the recent 1.0 release, here's more about it. Fiona is an open source OGR API for Python.

From the official page: "Fiona provides uncomplicated Python interfaces to functions in OGR, the best open source C/C++ library for reading and writing geographic vector data.

Fiona is designed to be simple and dependable. It focuses on reading and writing data in standard Python IO style, and relies upon familiar Python types and protocols such as files, dictionaries, mappings, and iterators instead of classes specific to OGR. Fiona can read and write real-world data using multi-layered GIS formats and zipped virtual file systems and integrates readily with other Python GIS packages such as pyproj, Rtree, and Shapely."

In the 1.0 announcement, Sean summarize what it offers:

  • Simplicity and less code.
  • Familiar Python types and protocols like files, dicts, and iterators instead of classes specific to GIS.
  • GeoJSON style feature records.
  • Reading and writing single and multi-layer files.
  • Reading zipped data, too.
  • A handy command line tool that upgrades "ogr2ogr -f GeoJSON".
  • Comprehensive tests.
  • 15 pages of narrative documentation.

And yes, Fiona is already updated to version 1.0.1.
