Patterns of landscape change in a rapidly urbanizing mountain region

We describe landscape changes in the context of a rapidly urbanizing mountain region, around the city of Grenoble in the French Alps. By combining a multi-source merging method and aerial photo-interpretation, we analyzed land cover dynamics during the 1998-2009 period. The analysis across 3 dates o...
