It is well-known that route distance estimates are influenced by the structure of the route. In particular, the number of features along the route (e.g. landmarks) and the structu...
We present an approach to modeling human interpretation of (real) geographic maps. While in Geographic Information Systems (GIS) the limitations for describing geographic knowledge...
For data to be successfully integrated, semantically similar database elements must be identified as candidates for merging. However, there may be significant differences between ...
In order to make database systems interoperate with systems beyond traditional application areas a new paradigm called \exporting database functionality" as a radical departur...
Application systems in the earth observation area can be characterised as distributed, platform-inhomogeneous, complex, and cost intensive information systems. In order to manage t...
