Compute the area of a geometry

g_area() computes the area for a LinearRing, Polygon or MultiPolygon. Undefined for all other geometry types (returns zero).

Usage

g_area(wkt)

Arguments

wkt

Character. OGC WKT string for a simple feature geometry.

Value

Numeric scalar. Area of the geometry or 0.

Note

LinearRing is a non-standard geometry type, used in GDAL just for geometry creation.
