ee.Geometry.BBox.length Stay organized with collections Save and categorize content based on your preferences.
Page Summary
The
lengthmethod returns the length of linear parts of a geometry, ignoring polygonal parts.For multi geometries, the length is the sum of the lengths of their components.
The method accepts optional
maxErrorandprojarguments to control reprojection tolerance and output units, respectively.The return type of the
lengthmethod is a Float.
| Usage | Returns |
|---|---|
BBox.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 BBox object.varbBox=ee.Geometry.BBox(-122.09,37.42,-122.08,37.43);// Apply the length method to the BBox object.varbBoxLength=bBox.length();// Print the result to the console.print('bBox.length(...) =',bBoxLength);// Display relevant geometries on the map.Map.setCenter(-122.085,37.422,15);Map.addLayer(bBox,{'color':'black'},'Geometry [black]: bBox');
