ee.Geometry.Polygon.cutLines

  • The cutLines method divides LineString, MultiLineString, and LinearRing geometries into smaller segments based on specified distances.

  • This method accepts a list of distances, an optional error margin, and an optional projection as input parameters.

  • Geometries other than LineString, MultiLineString, and LinearRing will be converted to an empty MultiLineString when using this method.

  • The distances provided determine the length of each segment and are measured in the units of the specified projection or meters if no projection is given.

  • Results and distance measurements will be in the projection provided or EPSG:4326 if none is specified.

 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.

UsageReturns
Polygon.cutLines(distances, maxError, proj)Geometry
ArgumentTypeDetails
this: geometryGeometryCuts the lines of this geometry.
distancesListDistances along each LineString to cut the line into separate pieces, measured in units of the given proj, or meters if proj is unspecified.
maxErrorErrorMargin, default: nullThe maximum amount of error tolerated when performing any necessary reprojection.
projProjection, default: nullProjection of the result and distance measurements, or EPSG:4326 if unspecified.
