Function: GeoDistance(Geometry left, Geometry right)
Returns the minimum distance between left geometry and right geometry.
If passed a string the geometry functions will automatically convert it into a geometry object.
Syntax
geoDistance( geometryValueLeft, geometryValueRight, decimalPlaces )
| Argument | Type | Description |
|---|---|---|
| geometryValueLeft | WTK String or Geometry Object | Geometry value being used to calculate the distance between the left geometry value and the right geometry value. |
| geometryValueRight | WTK String or Geometry Object | Geometry value being used to calculate the distance between the left geometry value and the right geometry value. |
| 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
geoDisjoint( "POLYGON ((30 10, 40 40, 20 40, 10 20, 30 10))", "POLYGON ((35 10, 45 45, 15 40, 10 20, 35 10))" )Returns the minimum distance between the two geometries as a Float.
