ArcGIS Spatial Query

Creates a spatial query which performs a spatial search for features in the supplied feature class and have the option to a LSO apply an attribute query via a WHERE clause.

Optionally a whereclause (e.g. "Income >") maybe applied if desired. The SQL syntax used to specify the WHERE clause are the same as that of the underlying database holding the data.</remarks> PublicESRI. ArcGIS.Geodatabase.IFeatureCursor Performspatialquery (ESRI.
