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).

MultiPolygon.area(maxError, proj)Float
this: geometryGeometryThe geometry input.
maxErrorErrorMargin, default: nullThe maximum amount of error tolerated when performing any necessary reprojection.
projProjection, default: nullIf specified, the result will be in the units of the coordinate system of this projection. Otherwise it will be in square meters.
