ee.Geometry.LinearRing.area

  • Thearea() method returns the area of a geometry, with points and line strings having an area of 0 and multi geometries having the sum of their components' areas.

  • The method takes optionalmaxError andproj arguments to control the accuracy of reprojection and the units of the result.

  • The result ofarea() is a Float.

  • Examples are provided for using thearea() method in both JavaScript and Python environments.

 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).

UsageReturns
LinearRing.area(maxError,proj)Float
ArgumentTypeDetails
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.
