Abstract
A method for executing a distributed spatial data query. The present invention allows a client to perform spatial queries against spatial data stored in a various formats in various separate databases. A view of the data is created in the relevant databases, wherein the spatial data is converted to WKB and stored as a BLOB. A federated server contains nicknames for the various database views, and also contains views of the data where the BLOB is converted back to a spatial data type. The federated server presents to clients an application view of the distributed heterogeneous spatial data such that the clients can treat the data as if it were a homogenous data source. Also taught is incorporating distributed non-spatial data into the application view by creating a nickname and a view on top of the nickname which derives spatial information from the non-spatial location information.
