One of the main strengths of Geographical Information Systems is its powerful ability to perform (spatial) analyses.  It can for example be used to compute vegetation succession or to quantify the effect of human disturbance on birds. We are experienced in developing (GIS) models for these calculations and perform spatial analyses on both raster and vector data.

Remote sensing is an important tool to classify vegetation cover from satellite images or aerial photographs. We use remote sensing to model the effect of water level changes in large river deltas, like the Inner Niger Delta in Mali, on changes in food supply for humans and birds. For the creation of an ecological network for large carnivores in Rumania and the Ukraine we have used several existing models like Marxan and Cluz. Marxan produces the best set of alternative conservation reserve networks on the basis of physical, ecological, social/ cultural and economic criteria, whereas CLUZ (Conservation Land-Use Zoning) is an ArcView GIS component that links with Marxan2.
