ee.Geometry.Point.length
Page Summary
The
length()method returns the length of the linear parts of a geometry, ignoring polygonal parts.For multi geometries, the length is the sum of the lengths of their components.
The method can optionally take
maxErrorandprojarguments to control reprojection error tolerance and the output units.If no projection is specified, the result is returned in meters.
| Usage | Returns |
|---|---|
Point.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 Point object.varpoint=ee.Geometry.Point(-122.082,37.42);// Apply the length method to the Point object.varpointLength=point.length();// Print the result to the console.print('point.length(...) =',pointLength);// Display relevant geometries on the map.Map.setCenter(-122.085,37.422,15);Map.addLayer(point,{'color':'black'},'Geometry [black]: point');
