Title: Automated analysis of elevation data in R+SAGA/GRASS
Venue: University of Zurich, Irchel Campus, 29 August & 30 August 2009
Workshop moderators: Tomislav Hengl / Carlos H. Grohmann
Registration fees: 150 CHF (PhD students)

Summary: This workshop aims at PhD students and professionals interested to use open source software
packages for processing of their elevation data. R is the open-source version of the S language for
statistical computing; SAGA (System for Automated Geoscientific Analyses) and GRASS (Geographic
Resources Analysis Support System) are the two most used open-source desktop GIS for automated
analysis of elevation data. A combination of R+SAGA/GRASS provides a full integration of statistics
and geomorphometry.

The topics in this workshop will range from selection of grid cell size, choice of algorithms for
DEM generation and filtering, to geostatistical simulations and error propagation. The workshop
moderators will demonstrate that R+SAGA/GRASS is capable of handling such demanding tasks as DEM
generation from auxiliary maps, automated classification of landforms, and sub-grid parameterization
of surface models.
The course will focus on understanding R and SAGA/GRASS syntax and building scripts that can be used
to automate DEM-data processing. Each participant should come with a laptop PC and install all
software needed prior to the workshop. Registered participants will receive an USB stick with all
data sets and overheads at the beginning of the course. Participants will follow a case study that
focuses on generation of DEMs, extraction of DEM parameters and landform classes, and implementation
of error propagation in geomorphometry.
