ee.Geometry.MultiLineString.area

  • Thearea method returns the area of a geometry.

  • The area of points and line strings is 0, while the area of multi geometries is the sum of the areas of their components, with intersecting areas counted multiple times.

  • Thearea method takes optionalmaxError andproj arguments to control the precision and units of the result.

  • The method is applicable to various geometry types, includingMultiLineString.

 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
MultiLineString.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.
