ee.Geometry.LineString.area

  • Thearea() method returns the area of a geometry, with points and line strings having an area of 0.

  • For multi-geometries, the area is the sum of their component areas, including intersecting areas.

  • Thearea() method takes optional argumentsmaxError for reprojection tolerance andproj to specify the output coordinate system units.

 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
LineString.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.

Examples

Code Editor (JavaScript)

// Define a LineString object.varlineString=ee.Geometry.LineString([[-122.09,37.42],[-122.08,37.43]]);// Apply the area method to the LineString object.varlineStringArea=lineString.area({'maxError':1});// Print the result to the console.print('lineString.area(...) =',lineStringArea);// Display relevant geometries on the map.Map.setCenter(-122.085,37.422,15);Map.addLayer(lineString,{'color':'black'},'Geometry [black]: lineString');
