ee.Geometry.Rectangle.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.

Usage	Returns
`Rectangle.length(maxError, proj)`	Float

Argument	Type	Details
this: `geometry`	Geometry	The input geometry.
`maxError`	ErrorMargin, default: null	The maximum amount of error tolerated when performing any necessary reprojection.
`proj`	Projection, 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 Rectangle object.
var rectangle = ee.Geometry.Rectangle(-122.09, 37.42, -122.08, 37.43);

// Apply the length method to the Rectangle object.
var rectangleLength = rectangle.length();

// Print the result to the console.
print('rectangle.length(...) =', rectangleLength);

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