ee.Geometry.LinearRing.cutLines
Stay organized with collections
Save and categorize content based on your preferences.
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.
