ee.Geometry.MultiLineString.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
MultiLineString.length(maxError, proj)Float
ArgumentTypeDetails
this: geometryGeometryThe input geometry.
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 meters.

Examples

Code Editor (JavaScript)

// Define a MultiLineString object.
var multiLineString = ee.Geometry.MultiLineString(
   [[[-122.088, 37.418], [-122.086, 37.422], [-122.082, 37.418]],
    [[-122.087, 37.416], [-122.083, 37.416], [-122.082, 37.419]]]);

// Apply the length method to the MultiLineString object.
var multiLineStringLength = multiLineString.length();

// Print the result to the console.
print('multiLineString.length(...) =', multiLineStringLength);

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