Product Availability
Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.
Remarks
esriSpatialRelUndefined
Used when the spatial relationship is not known at the time of object creation.
esriSpatialRelIntersects
Returns a feature if any spatial relationship is found. Applies to all shape type combinations.
esriSpatialRelEnvelopeIntersects
Returns a feature if the envelope of the two shapes intersects.
esriSpatialRelIndexIntersects
Returns a feature if the envelope of the query geometry intersects the index entry for the target geometry. Because it uses the underlying index grid, rather than the evelope of the feature, it is faster and is commonly used for return features for display purposes.
esriSpatialRelTouches
Returns a feature if the two shapes share a common boundary. However, the intersection of the interiors of the two shapes must be empty. In the Point/Line case, the point may touch an endpoint only of the line. Applies to all combinations except Point/Point.
esriSpatialRelOverlaps
Returns a feature if the intersection of the two shapes results in an object of the same dimension, but different from both of the shapes. Applies to Area/Area, Line/Line, and Multi-point/Multi-point shape type combinations.
esriSpatialRelCrosses
Returns a feature if the intersection of the interiors of the two shapes is not empty and has a lower dimension than the maximum dimension of the two shapes. Two lines that share an endpoint in common do not cross. Valid for Line/Line, Line/Area, Multi-point/Area, and Multi-point/Line shape type combinations.
esriSpatialRelWithin
Returns a feature if its shape wholly contains the search geometry. Valid for all shape type combinations.
esriSpatialRelContains
Returns a feature if its shape is wholly contained within the search geometry. Valid for all shape type combinations.
esriSpatialRelRelation
This is the expected value for ISpatialFilter::SpatialRel when using ISpatialFilter::SpatialRelDescription to define a custom spatial relationship. See the help on ISpatialFilter for details.
