Operators for geographical databases can be classified into two categories: thematic-oriented operators and network-oriented operators.

Network-oriented operators are based on graph manipulations whatever the geometric representation is (e.g., a transitive closure of a graph). In this paper we present network manipulations with a visual query language for a geographical database. A… CONTINUE READING
