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( geometryValueLeft, geometryValueRight, decimalPlaces )
| Argument | Type | Description |
|---|---|---|
| geometryValueLeft | WTK String 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.
