New GRASS GIS website

GRASS GIS is a fantastic software package, not only one of the oldest GIS packages still around, but also one that is continuously updating and improving thanks to a vibrant community.

Comparing human population density maps

Population density maps have multiple implications, e.g., to help relief agencies to better plan where they are needed most in case of disaster and in demographic, economic and environmental research.

Open source tools

Programs like R and GRASS GIS are incredible powerful. But occasionally, you'll need a functionality that is not available yet. Luckily, depending on the kind of functionality, it isn't terribly difficult to create your own scripts. In the past years I have created a few scripts that, I hope, are useful to others as well.
