Function: GeoDistance(Geometry left, Geometry right, Decimal Places)

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.
