What’s new in a nutshell

The new GRASS GIS 7.0.2 release provides 190 stability fixes and manual improvements.

About GRASS GIS 7: Its graphical user interface supports the user to make complex GIS operations as simple as possible. The updated Python interface to the C library permits users to create new GRASS GIS-Python modules in a simple way while yet obtaining powerful and fast modules. Furthermore, the libraries were significantly improved for speed and efficiency, along with support for huge files. A lot of effort has been invested to standardize parameter and flag names. Finally, GRASS GIS 7 comes with a series of new modules to analyse raster and vector data, along with a full temporal framework. For a detailed overview, see the list of new features. As a stable release series, 7.0.x enjoys long-term support.

We are pleased to announce that the 50th ICA-OSGeo Lab has been established at the GIS and Remote Sensing Unit (Piattaforma GIS & Remote Sensing, PGIS), Research and Innovation Centre (CRI), Fondazione Edmund Mach (FEM), Italy. CRI is a multifaceted research organization established in 2008 under the umbrella of FEM, a private research foundation funded by the government of Autonomous Province of Trento. CRI focuses on studies and innovations in the fields of agriculture, nutrition, and environment, with the aim to generate new sharing knowledge and to contribute to economic growth, social development and the overall improvement of quality of life.

The mission of the PGIS unit is to develop and provide multi-scale approaches for the description of 2-, 3- and 4-dimensional biological systems and processes. Core activities of the unit include acquisition, processing and validation of geo-physical, ecological and spatial datasets collected within various research projects and monitoring activities, along with advanced scientific analysis and data management. These studies involve multi-decadal change analysis of various ecological and physical parameters from continental to landscape level using satellite imagery and other climatic layers. The lab focuses on the geostatistical analysis of such information layers, the creation and processing of indicators, and the production of ecological, landscape genetics, eco-epidemiological and physiological models. The team pursues actively the development of innovative methods and their implementation in a GIS framework including the time series analysis of proximal and remote sensing data.

The GIS and Remote Sensing Unit (PGIS) members strongly support the peer reviewed approach of Free and Open Source software development which is perfectly in line with academic research. PGIS contributes extensively to the open source software development in geospatial (main contributors to GRASS GIS), often collaborating with various other developers and researchers around the globe. In the new ICA-OSGeo lab at FEM international PhD students, university students and trainees are present.

PGIS is focused on knowledge dissemination of open source tools through a series of courses designed for specific user requirement (schools, universities, research institutes), blogs, workshops and conferences. Their recent publication in Trends in Ecology and Evolution underlines the need on using Free and Open Source Software (FOSS) for completely open science. Dr. Markus Neteler, who is leading the group since its formation, has two decades of experience in developing and promoting open source GIS software. Being founding member of the Open Source Geospatial Foundation (OSGeo.org, USA), he served on its board of directors from 2006-2011. Luca Delucchi, focal point and responsible person for the new ICA-OSGeo Lab is member of the board of directors of the Associazione Italiana per l’Informazione Geografica Libera (GFOSS.it, the Italian Local Chapter of OSGeo). He contributes to several Free and Open Source software and open data projects as developer and trainer.

Note to English speakers

The FOSSGIS-conference is the largest German-language conference for Free and Open Source Software for GIS and Free Geodata hosting about 400 participants.

Today, the Conference Committee announced the “Call for papers” for 2014. Because the conference-language is German, the CfP is either.

The program committee will, however, also consider applications for talks or workshops held in English if they are deeemed to add to the quality of the conference. So if you don’t speak German, but are a FOSS/Open Data celebrity, or have a story that only you can tell, please do submit your talk. We are unlikely to be able to provide interpreters, but we’ll make sure you don’t get lost in Berlin. Please be aware that you can submit paper until November, 15. 2013. You can submit your abstract using our Conference Software.

We are looking forward to see you in Berlin March 19-21, 2014!

The Open Source Geospatial Foundation (OSGeo) is pleased to announce that the U.S. Internal Revenue Service (IRS) has accepted their application (PDF) for non-profit status under section 501(c)(4) of the tax code. Our 501(c)(4) status declares that OSGeo is a Social Welfare Organization. This determination affirms OSGeo’s role in serving the public through their 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 their 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.”

About the Open Source Geospatial Foundation

The Open Source Geospatial Foundation, or OSGeo, is a not-for-profit organization founded in 2006 whose mission is to support and promote the collaborative development of open geospatial technologies and data.  The Foundation provides financial, organizational and legal support to the broader open source geospatial community. It also serves as an independent legal entity to which community members can contribute code, funding and other resources, secure in the knowledge that their contributions will be maintained for public benefit.

On 7th Sep 2013 the final results from the 2013 elections for the open seats of the OSGeo Board of Directors have been published. There were four seats open and they have been filled by (in no particular order):
