Spatial Filter

A Spatial Filter defines a spatial searching constraint or query, using a spatial operator. The following spatial operators are supported:

  • Overlaps – The features to be returned may lie within, or partially within, the specified geometry. Boundaries that touch are considered overlapping.
  • DWithin – The features to be returned lie within the specified distance from the geometry.
  • Within – The features to be returned lie within the specified geometry. Boundaries can touch, but the inner object cannot have any points outside the containing boundary.
  • Beyond – The features to be returned lie outside the specified geometry.

Abbreviations for units of measure in addition to full names (for example, "mm," "millimeter," and "millimetre") are all supported:
