AI-generated Key Takeaways
-
cutLinesconverts LineString, MultiLineString, and LinearRing geometries into a MultiLineString by cutting them into parts no longer than the given distance. -
All other geometry types are converted to an empty MultiLineString.
-
The
distancesargument is a list specifying distances along each LineString to cut the line into separate pieces. -
The
maxErrorandprojarguments allow for control over reprojection error tolerance and the projection of the result and distance measurements.

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. |
