ee.Geometry.LinearRing.cutLines

Converts LineString, MultiLineString, and LinearRing geometries into a MultiLineString by cutting them into parts no longer than the given distance along their length. All other geometry types will be converted to an empty MultiLineString.

Usage	Returns
`LinearRing.cutLines(distances, maxError, proj)`	Geometry

Argument	Type	Details
this: `geometry`	Geometry	Cuts the lines of this geometry.
`distances`	List	Distances along each LineString to cut the line into separate pieces, measured in units of the given proj, or meters if proj is unspecified.
`maxError`	ErrorMargin, default: null	The maximum amount of error tolerated when performing any necessary reprojection.
`proj`	Projection, default: null	Projection of the result and distance measurements, or EPSG:4326 if unspecified.

Examples

Code Editor (JavaScript)

// Define a LinearRing object.
var linearRing = ee.Geometry.LinearRing(
    [[-122.091, 37.420],
     [-122.085, 37.422],
     [-122.080, 37.430]]);

// Apply the cutLines method to the LinearRing object.
var linearRingCutLines = linearRing.cutLines({'distances': [10, 100], 'maxError': 1});

// Print the result to the console.
print('linearRing.cutLines(...) =', linearRingCutLines);

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