The 2nd gvSIG Festival is underway!

News Date: 
26 Mar 2017

After the successful first gvSIG Festival in the last year, the virtual gvSIG conference, a second edition will be held this year, in May 16th and 17th. The novelty of this year is that users can send their proposals about projects done with gvSIG, that will convert this initiative in a more global and open event.

This event is free of charge and completely online, through the webinar service of the gvSIG Association, with the advantage to count with speakers from different countries and where users and developers from any part of the world can hold them.

If you have done any project with gvSIG and you want to present it at the gvSIG Festival, you can send a summmary to the following e-mail address: conference-contact@gvsig.com, explaining the project. The summary will have no more than 300 words, it has to be written in Spanish or English, and you have to indicate the title and the language of the presentation.

Once the program is configured it will be published at the event website, and registrations will be opened.

Registration for STDM Code Sprint 2017 opened

News Date: 
26 Mar 2017

Dear All,

the Social Tenure Domain Model (STDM) is a concept to model a continuum of people-to-land relationships in informal environments. Legacy cadastre and land registry software from the developed world has proven to lack flexibility and literally does not meet the bill, financially.

The Global Land Tool Network (GLTN) has closed this gap by developing fit-for-purpose STDM software tools under an Open Source license based on well known core technology including QGIS, PostGIS, GDAL/OGR and Sahana Eden. To further extend the functionality of these tools and also to improve the know-how in the region, GLTN organizes a code sprint.

The code sprint is free of cost to attend thanks to the kind sponsorship of GLTN and OSGeo. A formal application is required including a CV and a list of practical experience in the field. Find more details here:


There are limited travel grants available for applicants who fit the profile and preferably come from Africa, Asia, and South America. Application closes on March 31st. Register here: http://bit.ly/stdm-code-sprint

Please apply soon, seats are limited. This is hot. With FOSS4G 2018 coming up in Africa we really, really want to support and grow the African OSGeo Local Chapter!

Please feel free to forward to your domain, we are trying to avoid lots of cross postings.

Considered keywords include: land innformation, land administration, cadastre, social tenure, land rights, open source GIS, QGIS, PostGIS, LADM.

Thank you and best regards,

Arnulf Christl
(OSGeo GLTN Liaison Officer, Organizer)

OSGeo is accepted as a mentor organization for GSoC 2017!

News Date: 
28 Feb 2017

Dear OSGeo community,

We are proud to announce that OSGeo has been selected as a mentor organization for the 2017 edition of GSoC! See all selected orgs here.

From now until March 20, potential student participants are invited to discuss application ideas with mentoring organizations/OSGeo’s projects (see the detailed timeline.

Mentors are invited to let us know the project they intend to mentor, and to subscribe to the Google webpage. Before committing for mentorship, please read and accept the mentor’s responsibilities.

Once we have verified the correspondence between the mentors and the idea, we will proceed to appointing them in our wiki page and connect the mentors to the OSGeo organization on the Google website, from which it’ll be possible for the mentors to evaluate the proposals. Mentors: please offer guidance to the students that contact your software communities, and offer them a code challenge in line with the project that they want to apply for.
Would-be students: please read carefully the recommendations and browse the ideas page.

All: please subscribe the soc mailing list.

Let’s begin!!

Summer School in Geocomputation - Italy - June 2017

News Date: 
24 Feb 2017

Dear colleagues,

registration open now for our International Summer School organized by Spatial Ecology (http://www.spatial-ecology.net) held at the Univ. of Basilicata, in the magnificent town Matera, Italy.

Geocomputation using free and Open Source Software (19th-23th June 2017)

A 5 days intense experience opening new horizons on the use of the vast potentials of Linux environment and the command line approach for data processing using Bash, AWK, Python, GRASS, QGIS, GDAL/OGR, R, PKtools, OpenForis. We will guide newbies and experienced GIS users who have never used a command line terminal to a stage which will allow them to understand and apply very advanced open source data processing routines. Our focus is to enhance a self-learning approach. This allows participants to keep on progressing and improving their skills in a continuously evolving technological environment.

The 6th GIS-focused algorithm competition, GISCUP 2017, co-located with ACM SIGSPATIAL GIS 2017, November 7 - November 10, 2017, Los Angeles, CA, USA


This year will be the 6th GIS-focused algorithm competition, GISCUP 2017, co-located with the 2017 ACM SIGSPATIAL GIS conference. ACM SIGSPATIAL hosts an annual algorithm contest with the goal of encouraging innovation in a fun way. The winners will be announced at the ACM SIGSPATIAL GIS conference in November 2017. Contest participants will submit original computer programs to be evaluated by the contest organizers on common datasets.

This year’s contest will focus on the growing research area of trajectory computing. Massive amounts of spatial trajectories are generated nowadays by smartphones, infrastructure, computer games, natural phenomena, and many other sources. A trajectory consists of a time series of locations with the assumption that some sort of interpolation (often piecewise linear) is reasonable. In this way, trajectories are one-dimensional geometric objects, but their representation in computer systems is usually zero-dimensional as a series of pairs of location and time, for example.

Trajectory similarity is a very basic problem when dealing with this type of data and many different ways of comparing trajectories have been proposed. In this challenge, we concentrate on a very intuitive measure called Fréchet distance with hard computational complexity, but superior quality in theory and practice.

The Fréchet distance is defined as the minimal length of a leash connecting a dog on one trajectory with its owner on a second trajectory, both never moving backwards. For this challenge, the "true" Fréchet distance shall be used, though teams are free to exploit the existing approximations including the Discrete Fréchet distance as they wish. The challenge for this year consists of finding and combining spatiotemporal indexing schemes with efficient algorithms for Range Queries in very large databases of trajectories. The approaches will be evaluated on a multitude of real and synthetic datasets, a sample datasets can be found on the download page page.

In summary, the key topics that are being addressed in this year’s cup are the following:

- Spatio-temporal Big Data
- Trajectory Computing
- Computational Geometry
- Indexing and Retrieval in Spatial Computing

The top three teams will be provided with cash and / or other prizes. In addition to these prizes, the top three teams will be invited to submit a four page paper for a contest paper session to be held at the 2017 ACM SIGSPATIAL GIS conference. These papers will be subject to review and acceptance by the contest organizers, but it is expected that each of the top three teams will have their paper in the conference proceedings and a ten-minute presentation in the contest session.

At least one team member of each winning team must register for the 2017 ACM SIGSPATIAL GIS conference.

Important Dates:

July 30, 2017 Deadline for Submissions
August 17, 2017 Invitation of papers for the best submissions
August 24, 2017 Submission deadline for invited papers
