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

Syntax

geoGetNum( geometryValue, decimalPlaces)

Argument

Type

Description

geometryValue

WTK String or

Geometry Object

The geometry to test for number of geometries.

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

geoGetNum("MULTIPOLYGON (((0 0, 0 2, 2 2, 2 0, 0 0)), ((0 0, 0 -2, -2 -2, -2 0, 0 0)))")

Returns the number of geometries as an Integer
