RE: [Algorithms] UTM mapping

[Discoe, B. <ben...@in...>]

The data is definitely a simple heightmap.  What are you trying to do with
it?  The geographic extents are provided (optionally in UTM) so that you can
match it to other geospatial data you have.  If you just want to draw the
data by itself, you can ignore the extents.
