Power User Workshop: GRASS image processing (with focus on optical and Lidar data)
GRASS is a full-featured, open source Geographic Information System
(GIS) with graphical user interface and scripting environment for
raster and vector spatial analysis. The participants of this workshop 
will gain hands-on experience with a specialized field, the optical and
Lidar remote sensing and image processing.

The workshop is organized in two parts. In part 1 we will show optical 
data processing and image classification. In part 2 we focus on LIDAR
(Light Detection and Ranging), which is one of the most recent
technologies in surveying and mapping. Lidar allows us to obtain very
accurate and high resolution Digital Surface Models (DSM). For many
applications the Digital Terrain Model (DTM) is needed: we will
automatically detect and discard from the DSM all the objects
(buildings, trees, etc.) present on the terrain. Participants will work
with Lidar data and learn how to process massive point data sets in
GRASS. We conclude with watershed analysis using Lidar-based DEMs and
terrain change studies using multitemporal DEMs.
