The GEOMETRY abstract data type facility provided by the HiRDB Spatial Search Plug-in makes it possible to define positional information in a map as spatial data (two-dimensional data with X and Y coordinates specified) and to register it into the HiRDB database.

The Within abstract data type facility provided by the HiRDB Spatial Search Plug-in can be used to evaluate the spatial relationships between the graphic object specified in a retrieval condition expression and a GEOMETRY-type graphic object, and to determine whether or not the specified graphic object is included. For example, one could retrieve "banks located within 100 m of the train station."

The IntersectsIn abstract data type facility can also be used to evaluate the spatial relationships between the graphic object specified in a retrieval condition expression and a GEOMETRY-type graphic object, and to determine whether or not the specified graphic object is included or intersects. For example, one could retrieve "roads, train tracks, and rivers that pass through a certain area."
