Short description of this site

This website decribes a topology preserving database structure, which is implemented in C# and Postgres RDBM system. This logic is basically different than the OGC standard (Open Geospatial Consortium), where each spatial object contains its own nodes, thus there is no information on adjacency. In case of adjacent polygons, nodes are stored redundantly, since the common nodes are stored for both polygons. The structure, which is introduced here, is a redundancy-free, topology preserving data structure. Nodes and polygons are stored in separate Postgres tables, and the relatinship between them creates the polygons. The name of this structure is Topo-Logix.
