How GeoCrossWalk Makes Your Service Geo-smart 

GeoCrossWalk is fundamentally a spatially enabled database. This allows geographic features stored in the database (say for example representations of rivers, towns, postal areas) to be queried spatially.

Spatial queries such as containment (is this feature contained by another feature) are possible. By using geography and the relationships between and amongst geographic features, users can answer a wide variety of geographical questions:

  • is this feature near another?
  • what features are within this area?
  • how many features of a certain type  are there?

The heart of GeoCrossWalk is its gazetteer and the rich feature store it represents of real world objects. Over and above this, we have established middleware which allows end users to interrogate and query this spatial database using conventional web protocols.
