Abstract: A method, spatial data system, and computer program product for managing spatial data stored in a database by indexing spatial object identifiers associated with spatial objects of varying dimensions using a spatial index for each spatial object identifier comprised of one or more index coordinate variables that define a single point spatially related to the spatial object and one or more index dimension variables that define a bounding shape based on the spatial object's size. The spatial data system is configured to allow querying of the database to determine spatial object identifiers, and associated spatial objects, within a search area by identifying spatial indexes that define bounding shapes intersecting the search area and producing the results on a user interface.
