The desired geometric operations can be computed in planar space, and reprojected back to geodetic.
-### Does GEOS support coordinates with measures (M)?
-
-No, the GEOS coordinate model only supports X,Y and Z ordinates.
-We hope to add support for M, and also a more efficient XY coordinate storage representation.
