*** Tip of the Week: Acquiring Vertex Elevation Values From Points Lying on Them ***

One of our GeoTools users, and a good friend, Werner Macho from Vienna, came up with this request today, "I have a polyline which has lost all its elevation values. Some idiot converted it into a 2d polyline and all the elevations are now reduced to 0.0. Is there a way to get it back using GeoTools?"

Fortunately, he still had the individual point objects with the elevations at the same location where the polyline vertices were.

We devised a solution for him using a couple of GeoTools commands. Read more about it in my blog post:
