Thanks Mike!
I took your advice and specified the projection during the conversion
instead of trying to convert the non-earth tab files which I guess doesn't
work...
I thought because I was setting up a custom projection, the arclink_map
sun program wouldn't work because you don't have a mapinfow.prj
file -- anyone know how you'd specify a custom projection with
arclink_map? Is it all put on the command line?
But luckily, the windows ArcLink program does read the mapinfow.prj
file, and this made it all good, the line I added (see below) to the
mapinfow.prj file is exactly what is needed for this Paraguay data set.
(Actually I'm still waiting for confirmation it's WGS 84, but it's close
enough for my purposes at this point.)
Thanks Again for that Clue!
