Spatial query processing with query window index
Abstract:
One example method of spatial query processing using query window indexes includes receiving a spatial query on spatial data that has an associated spatial data index. The spatial query specifies a query window. A query window index structure is constructed that describes a geometry of the query window. The query window index structure is compared to the spatial data index and, when necessary, to the spatial data to determine a spatial relationship between the query window and the spatial data.
