AI-generated Key Takeaways
-
The
cutLinesmethod converts LineString, MultiLineString, and LinearRing geometries into a MultiLineString by cutting them into parts no longer than the specified distance. -
Other geometry types are converted to an empty MultiLineString.
-
The method takes
distances,maxError, andprojas arguments.

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. |
