Some time around 20 years ago I had a system by which I could download
USGS topographic data and convert it to a POV-Ray height field. This was
on a Macintosh running OS 9, I think.
I am now on Windows 11 and I have lost all of my old POV-Ray files for
reference.
I think it was a .DAT file or .DOT file that I had to convert.
Does such a thing exist anywhere anymore?
