]IGeometry.SpatiallyEquals method
Determines if this geometry spatially equal to a specified geometry.
public bool SpatiallyEquals(IGeometry other)
| Parameter | Type | Description |
|---|---|---|
| other | IGeometry | A geometry. |
Return Value
true if this geometry “spatially equals” to specified geometry. false otherwise.
Exceptions
| exception | condition |
|---|---|
| ArgumentNullException | Argument is null. |
| ArgumentException | One of the geometries is invalid in such way that operation can not be finished. |
| ArgumentException | SpatialReferenceSystem of geometries are not equivalent. You can use SpatialReferenceSystemTransformation in order to convert geometries to the same spatial reference system. |
Remarks
This method tests equality in terms of DE-9IM intersection matrix. It does not depend on order of components (e.g. order of interior rings in polygon), Z and M values. Basically, it tests that two geometries occupy the same “space” when projected on two dimensional space. This method is equivalent to:
this.Relate(other, "T*F**FFF*");
See OpenGIS Simple Features Specification for more details about DE-9IM.
