Today, spatial analyses are carried out computerised via Geographic Information Systems (GIS).
The most important interpretation techniques are:
- the investigation of corridors (buffers) around existing objects,
- the search for objects with the help of distinctive location and factual criteria,
- the calculation of catchment areas in networks,
- three-dimensional analysis of area structure (e. g. gradient ratios),
- blending of spatial and/or factual information on objects from different thematic levels
- selective questioning in the data bank about spatial, time-related or factual aspects
Results are (mostly) maps that display the important information space-oriented.
