ee.Geometry.MultiPoint.perimeter

Returns the length of the perimeter of the polygonal parts of the geometry. The perimeter of multi geometries is the sum of the perimeters of their components.
UsageReturns
MultiPoint.perimeter(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 MultiPoint object.
var multiPoint = ee.Geometry.MultiPoint([[-122.082, 37.420], [-122.081, 37.426]]);

// Apply the perimeter method to the MultiPoint object.
var multiPointPerimeter = multiPoint.perimeter({'maxError': 1});

// Print the result to the console.
print('multiPoint.perimeter(...) =', multiPointPerimeter);

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