The pgRouting Team is pleased to announce the release of pgRouting 2.0.0

News Date: 
24 Sep 2013
Details: 

This 2.0 release brings a number of major new features that are summarized in this document.

Major New Features in pgRouting 2.0

pgRouting extends the PostGIS/PostgreSQL geospatial database to provide geospatial routing and other network analysis functionality.

This library contains following features:

  • All Pairs Shortest Path, Johnson’s Algorithm **NEW**
  • All Pairs Shortest Path, Floyd-Warshall Algorithm **NEW**
  • Shortest Path A*
  • Bi-directional Dijkstra Shortest Path **NEW**
  • Bi-directional A* Shortest Path **NEW**
  • Shortest Path Dijkstra
  • Driving Distance
  • K-Shortest Path, Multiple Alternative Paths **NEW**
  • K-Dijkstra, One to Many Shortest Path **NEW**
  • Traveling Sales Person **NEW Implementation**
  • Turn Restriction Shortest Path (TRSP) **NEW**
  • New functions for creating routing topology
  • New functions for analyzing a graph for problems

Migration Guide

pgRouting 2.0 is **not** backwards compatible with the 1.x version. This is a significant overhaul of the whole pgRouting environment and we have renamed all the functions and rationalized the arguments and return types. While this will be a painful migration for 1.x applications, we believe the new functionality, the high quality of the code, and new documentation will make it much easier to grow the product and support it over future releases.

Arnulf Christl Receives Sol Katz Award

News Date: 
20 Sep 2013
Details: 
Arnulf Christl was honored today with the 2013 Sol Katz Award for Geospatial Free and Open Source Software during the FOSS4G 2013 conference in Notthingham, UK. The award was presented by Jeff McKenna, the president of OSGeo. Arnulf's dedication to open source geospatial software, and the community and ideals around it are widely recognised. He played a large role in the Mapbender project, and was a founding director of OSGeo, as well as serving as president for several years. He has also been a key bridge between OSGeo and the Open Geospatial Consortium, emphasizing the duality of open source and open standards. He continues to advocate for these ideals inside and outside OSGeo.

Background

The Sol Katz Award for Geospatial Free and Open Source Software is awarded annually by OSGeo to individuals who have demonstrated leadership in the GFOSS community. Recipients of the award will have contributed significantly through their activities to advance open source ideals in the geospatial realm. The hope is that the award will both acknowledge the work of community members, and pay tribute to one of its founders, for years to come. Sol Katz was an early pioneer of GFOSS and left behind a large body of work in the form of applications, format specifications, and utilities. In the early 80's, Sol assisted in the development of a public domain GIS package called MOSS (Map Overlay and Statistical System). This software was arguably the first open source GIS software in the world. Sol would later go on to release and maintain PC MOSS. He was also one of the first involved in public data translator utilities. Utilities that he developed for converting DEMs and reading SDTS files were contributed back to the geospatial community, and are still available today. Sol was also a frequent contributor to many geospatial list servers, providing much guidance to the geospatial community at large. Sadly, after fighting Non-Hodgkin's Lymphoma for almost a decade, Sol died April 23, 1999 in bed. His legacy will always live on in the GFOSS world.

News Date: 
20 Sep 2013
Details: 
The GeoTools community is happy to bring you the latest GeoTools 10.0 download:
As an alternative to downloading this release has been deployed to our maven repository.

This release is made in conjunction with GeoServer 2.4.0 and GeoWebCache 1.5.0. We would to thank everyone who has helped out with testing.

Please see the GeoTools 10.0 Release Notes for additional details.

About GeoTools 10.x Series

Summary of the new features for the GeoTools 10.x series:
  • Structured grid coverage readers allow raster data sources that publish composite data products to expose individual rasters (ie granules) for processing, while still providing a seamless experience for rendering. The mosaic and NetCDF modules are the first ones to implement these new interfaces.
  • Efficient support for multiple coverages in GridCoverageReader provides ad-hoc access to raster formats that publish more that one data product. A image mosaic made of NetCDF granules and single file NetCDF sources are the first implementors of these new capabilities
  • new implementation of Shapefile DataStore (based on ContentDataStore superclass). This upgrade should be seamless for all users using DataStoreFactoryFinder. If you explicitly made use of the ShapefileDataStore or IndexedShapefileDataStore class please check the upgrade instructions.
  • The transform module graduated to supported status, providing a seamless way to rename, retype and hide SimpleFeatureSource attributes, as well as creating new ones based on OGC Expression
  • Additional OGC modules for the WCS 2.0 and WCS 2.0 EO models as well as adding XML parsers and encoders
The 10.x series has a number of research and development activities that may be of interest:
  • NetCDF has been updated to take advantage of the new coverage API introduced above
  • GeoPackage: a sample implementation of the geopackage spec that is currently being developed by the OGC
While exciting, this functionally is looking for volunteers and/or funding to meet our quality assurance standards. If you are interested please introduce yourself on geotools-devel (or check out options for commercial support).

Enjoy,

Open Source Geospatial Laboratory established at ETH Zurich, Switzerland

News Date: 
19 Sep 2013
Details: 

We are pleased to announce the establishment of ICA-OSGeo Open Source Geospatial Laboratory (OSGL, see [0]) at ETH Zurich, Switzerland [1]. The OSGL at ETH Zurich is part is part of the Institute of Cartography and Geoinformation, chair of Cartography [2]. The preceding Institute of Cartography was founded in 1925 by Professor Eduard Imhof, one of the main founders of modern academic cartography. It is therefore the oldest university institute in cartography world-wide. In 2011, with the establishment of the new chair of Geoinformation Engineering, the scope of activities of the institute was expanded and its name was adapted. In cartography, the institute strives to maintain its leading position in topographic cartography (relief representation), thematic cartography, and atlas cartography (school atlases, national atlases) by exploiting and further developing cartographic knowledge and adapting it to new interactive technologies and application domains. Geoinformation Engineering aims at analyzing, representing, modelling, and visualizing spatio-temporal decision processes and integrates such models in mobile geoinformation services and spatial information technologies.

The OSGL at ETH Zurich will be actively implementing the Memorandum of Understanding signed between the International Cartographic Association (ICA) and the Open Source Geospatial Foundation (OSGeo), with the vision to support the development of open-source geospatial software technologies, training and expertise. It also aims to provide support for increasing the number and quality of open source teaching and training materials for Cartography and GIS. As a proud member of the ICA-OSGeo Network [3], the ETH Zurich OSGL is focusing on Education, Open Geodata and on Cartographic and Geospatial Research. Additionally the laboratory is participating in the ICA Commission on Open Source Geospatial Technologies [4] and through the Institute of Cartography and Geoinformation [5] as an associate member in Open Geospatial Consortium (OGC) [6].

The lab starts with expertise in several OSGeo projects such as Quantum GIS, OpenLayers, PostGIS and GDAL/OGR. A special attention will be given to QGIS Server, since it was conceived as a research project at the Institute of Cartography and Geoinformation [2]. Furthermore the lab is proud to have joined a collaboration in the areas of Education and Research with the industry partner Sourcepole [7].

The ETH Zurich OSGL will be led by Dr. Ionuț Iosifescu [8] with support from several members of the Institute of Cartography and Geoinformation. Please check the lab webpage for the full list of team members and the assigned areas of responsibility, as well as for the upcoming training possibilities [9].

OSGeo is a not-for-profit organisation founded in 2006 whose mission is to support and promote the collaborative development of open source geospatial technologies and data.

ICA is the world authoritative body for cartography and Geographic Information Science.

OSGeo Receives 501(c)(4) Tax Exempt Status

News Date: 
13 Sep 2013
Details: 

OSGeo is pleased to announce that the U.S. Internal Revenue Service (IRS) has accepted our application (PDF) for non-profit status under section 501(c)(4) of the tax code. Our 501(c)(4) status declares that we are a Social Welfare Organization. This determination affirms OSGeo's role in serving the public through our mission, focused around Open Source Geospatial software.

This determination helps ensure that the organization will not have to pay US federal taxes on money accumulated toward the fulfilment of our mission. Unfortunately, unlike a 501(c)(3) (Charitable) status, this does not allow financial contributors to OSGeo to treat the contributions as a charitable contribution which can have a tax benefit for US tax payers. There should still be no problem with commercial organizations treating contributions to OSGeo as a business expense.

OSGeo owes a special debt to past Executive Director Tyler Mitchell, and current Treasurer Daniel Morissette who have carried this process to a successful conclusion after several years of work. Current OSGeo President, Jeff McKenna, says "Both Daniel and Tyler should be thanked by the entire community for their dedication to such a challenging task. Our future foundation events, and OSGeo in general, will benefit from their hard work for years to come."
