Perform linear Interpolation of Z elevations along a polyline in GeoTools
Bangalore, India
Often, you may have polylines in which some vertices have a zero elevation while others have non-zero elevations.
The GT_PL_INTER command fills in all the zero [0.0] elevation vertices with non-zero values based on a linear distance interpolation between the non-zero vertices.
