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.

Open Source Geospatial Foundation (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.

International Cartographic Association (ICA) is the world authoritative body for cartography and GIScience. See also the new ICA-OSGeo Labs website.

In my presentation I briefly review 3 decades of Open Source GIS development, from the 1980th to the present.

Earlier this Last year, in June, Don Meltz wrote an interesting blog “ArcGIS vs QGIS Clipping Contest Rematch” where he let compete ArcGIS and Quantum GIS in a clipping contest. The benchmark contest data set in question is a 878MB ZIP file (ContourClipTest.zip with the (guessed) EPSG Code 2260 – NAD83 / New York East (ftUS)). The blog page gained a lot of comments, even from ESRI since some ArcGIS versions crashed on this test data set.

Find below the various timings compiled from the blog and the comments:

Proprietary software

Software Processing time Hardware/Software
ArcGIS 9.3 crash after 1h 9min: ERROR 999999: Error executing function. Invalid Topology [4gb file limit.] Failed to execute (Clip) unknown
ArcGIS 10.0 crash likewise unknown
ArcGIS 10.1 ESRI promise to calculate it in 34 seconds in this updated version (did anyone test?) unknown
GlobalMapper (version?) 30 mins unknown
GlobalMapper v11.02 49 sec Windows XP w/ 3.5GB RAM
Manifold 8 (64bit) 31 min Windows XP64 16 gb. RAM and 2.33 GHz

Note: The two GlobalMapper results are a bit funny, perhaps always minutes?

Free and Open Source Software

Software Processing time Hardware/Software
Quantum GIS (version?; Simple features) 4-5 min unknown
GRASS GIS 7 (topological GIS) 5 min Dell PowerEdge 2950 from 2008, Intel Xeon 2.66GHz, 8GB RAM
gvSIG to be done
PostGIS to be done

Notes: Hope volunteers will test this also on gvSIG and PostGIS (and other FOSSGIS)! Please report…
