geoEqualsTopo(Geometry left, Geometry right), Tests whether the left geometry is topologically equal to the right geometry as defined by the SFS equals predicate.

Function: geoEqualsTopo(Geometry left, Geometry right)

Tests whether the left geometry is topologically equal to the right geometry as defined by the SFS equals predicate.

If passed a string the geometry functions will automatically convert it into a geometry object.

Syntax

geoEqualsTopo( "Well Known Text" Left, "Well Known Text" Right geometryValueLeft, geometryValueRight 

ArgumentTypeDescription

Examples

geoEqualsTopo(30.10, 50.65 "POLYGON ((30 10, 40 40, 20 40, 10 20, 30 10))", "POLYGON ((35 10, 45 45, 15 40, 10 20, 35 10))" )

Returns a Boolean true if the two geometries are exactly equal.
