geoEqualsTopo( "Well Known Text" Left, "Well Known Text" RightGeometry left, Geometry right, Decimal Places), 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, Decimal Places)
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, decimalPlaces )
...
Argument | Type | Description |
---|
geometryValueLeft | WTK String |
Examples
or Geometry Object | Geometry value being used to calculate if it is topologically equal to the geometryValueRight | |
geometryValueRight | WTK String or Geometry Object | The geometry being checked. |
decimalPlaces | Integer | The number of decimal places to use in the geometry calculations. Defaults to 0 if not provided. Can also take negative values e.g. -1 uses geometry to the nearest 10. |
Examples
geoEqualsTopo( "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.
