Returns the area of the geometry. Area of points and line strings is 0 and the area of multi geometries is the sum of the areas of their components (intersecting areas are counted multiple times).
Usage
Returns
MultiPolygon.area(maxError, proj)
Float
Argument
Type
Details
this: geometry
Geometry
The geometry input.
maxError
ErrorMargin, default: null
The maximum amount of error tolerated when performing any necessary reprojection.
proj
Projection, default: null
If specified, the result will be in the units of the coordinate system of this projection. Otherwise it will be in square meters.
