Zusammenfassung
The Central Andes of northern Chile, southwestern Bolivia and northwestern Argentina are studied by a research project supported by the Deutsche Forschungsgemeinschaft (SFB 267). The main topics of these geological and geophysical investigations are the orogeny of the Andean mountains and the crustal development at an active continental margin. The "Andean GIS" is designed as a tool for data collection, management, overview, analysis and mapping. The integration of different data supports the interdisciplinary work within the research project and provides a base for the exchange of data and ideas between the different geoscientific disciplines of the project. Remote sensing data represent the basic information level in the "Andean GIS". More than 30 geocoded Landsat TM scenes were processed and integrated into the GIS as well as digital elevation models and orthoimages created from SPOT stereo images. The structure of the GIS contains tools for data overview, visualization, and data input for non-GIS experts. The data management and the applications are developed by the GIS manager in cooperation with project scientists. After the initial development during the last two years, the structure and content of the Andean GIS have to be kept up-to-date continuously in order to fulfill its function as a "common link" between the different groups of scientists.
