ee.Geometry.LineString.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).

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)Colab (Python)
// Define a LineString object.
var lineString = ee.Geometry.LineString([[-122.09, 37.42], [-122.08, 37.43]]);

// Apply the area method to the LineString object.
var lineStringArea = 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');
