Transforms the geometry to a specific projection.
Usage
Returns
MultiPolygon.transform(proj, maxError)
Geometry
Argument
Type
Details
this: geometry
Geometry
The geometry to reproject.
proj
Projection, optional
The target projection. Defaults to EPSG:4326. If this has a geographic CRS, the edges of the geometry will be interpreted as geodesics. Otherwise they will be interpreted as straight lines in the projection.
