ee.Geometry.Polygon.area

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
Polygon. 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.
