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 | MultiLineString.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 WGS84 if unspecified. |
Examples
Code Editor (JavaScript)
// Define a MultiLineString object.
var multiLineString = ee.Geometry.MultiLineString(
[[[-122.088, 37.418], [-122.086, 37.422], [-122.082, 37.418]],
[[-122.087, 37.416], [-122.083, 37.416], [-122.082, 37.419]]]);
// Apply the cutLines method to the MultiLineString object.
var multiLineStringCutLines = multiLineString.cutLines({'distances': [10, 100], 'maxError': 1});
// Print the result to the console.
print('multiLineString.cutLines(...) =', multiLineStringCutLines);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(multiLineString,
{'color': 'black'},
'Geometry [black]: multiLineString');
Map.addLayer(multiLineStringCutLines,
