ee.Geometry.LineString.length

Returns the length of the linear parts of the geometry. Polygonal parts are ignored. The length of multi geometries is the sum of the lengths of their components.

UsageReturns
LineString.length(maxError, proj)Float
ArgumentTypeDetails
this: geometryGeometry

The input geometry.

maxErrorErrorMargin, default: null

The maximum amount of error tolerated when performing any necessary reprojection.

projProjection, default: null

If specified, the result will be in the units of the coordinate system of this projection. Otherwise it will be in meters.

Examples

Code Editor (JavaScript)

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

// Apply the length method to the LineString object.
var lineStringLength = lineString.length();

// Print the result to the console.
print('lineString.length(...) =', lineStringLength);

// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(lineString,
             {'color': 'black'},
             'Geometry [black]: lineString');
