Geographical Information Systems (GIS) are used for collecting, storing, specifying, analyzing and presenting spatial patterns and processes. The fundamental spatial data (divided into regions and administrative units, maps, topographic elevation models, orthophotos, and satellite data) is managed and made available for use in the GIS.

At the national level, the NFI is responsible for the compilation and analysis of additional information pertaining to Swiss forest development. GIS tools are also used for spatially explicit modeling. For example, process modeling enables extensive coverage modeling of Swiss avalanche protection forests. Users can also apply (geo-) statistical methods to calculate the distribution of the 90 most important Swiss woody plant species.
