Hands-on course to GIS and Remote Sensing with GRASS GIS

The hands-on GRASS GIS course at ITC – University of Twente on November 3rd, 2017 was a great success. The course, organized by ITC and OSGeo.nl, offered a very nice introduction to GRASS GIS by Veronica Andreo and a guided tour about working with GRASS GIS by Sajid Pareeth.


As part of the course, we also developed three modules with hands-on exercises on different topics related to raster time series processing, remote sensing images processing and spatial interpolation in GRASS GIS.

All the course materials are available online, so check them out and enjoy 🙂

One of the advantages of Freeplane is that you can export your mind map in many formats. This including different formats for online publishing, e.g., as java applet or a clickable map image version.The java applet offers a basic interface to your mindmap, including search and expanding / collapsing of the nodes.

Check out this article ‘Let the four freedoms paradigm apply to ecology’ (but don’t get it from ScienceDirect)

There is an interesting letter (Let the four freedoms paradigm apply to ecology) in Trends in Ecology and Evolution by Duccio Rocchini and Markus Neteler arguing that science should use open source software. Basically, using open source software will help researchers to test, reproduce and build upon work of others, while being (more) sure that the code / algorithms they are using are robust and reliable.
