Spatial queries
 use the "shape" data from two themes to find records in the "source" theme that meet conditions from a "selection" theme. For example, spatial queries can be used to find "points" (or wells) contained in leases, two lease files that overlap, and a variety of other conditions based on the interaction of the geometry of the "shapes".
The following example finds all wells in the "Shape_Leases" theme.
The selected wells were then saved as the "WellsInLeases" theme.
