We continue with the eighth module of the free GIS course, where we continue to show you how to work with raster data in gvSIG Desktop, in this case calculating several parameters (NDVI, CTVI,…) related to vegetation index and learning to work with unsupervised classification tools.

To follow the course you need:

• gvSIG Desktop, that you can download here: http://www.gvsig.com/en/products/gvsig-desktop/downloads
• Data used in the exercises, available from: http://downloads.gvsig.org/download/documents/learning/gvsig-courses/cartography/Raster_data.zip

8.1 Vegetation index

8.2 Unsupervised classification

Arrived at this point of the course, we want to introduce you to your teacher Giuliano Ramat, who made this course in the framework of a collaboration between the gvSIG Association and GISMAP.
