Check out the
com.vividsolutions.jts.triangulate.ConformingDelaunayTriangulator class in
JTS . Given a set of points, it creates a TIN structure, so all you would
need to do is define a format reader for the TIN. In our client's
implementations we used gridded and zipped CSV files - performed really
well with the java zip stream and opencsv library.
