If anyone still has the IDL 4.0 User's Guide (1995) please look at page
19-10 to help in answering my question here. The picture for the
Oblique Cylindrical Equidistant map projection interests me because I would
like to see both poles. I'm using IDL 5.2 on UNIX so that might make
a difference, but if I type the command on page 19-11:
map_set, 0, 0, 45, LONDEL = 20, LATDEL
= 20, $
/GRID, /CONTINENT, /CYL, TITLE='...'
to produce this map, it comes up with a simple cylindrical map, but
the whole map actually rotates 45 degrees, ie the edges of the map are
now 45 degrees from their original horizontal and vertical positions.
I would expect the ROT value of
45 to create the map on page 19-10 as the book says, but it does not.
Can anyone explain this discrepancy in the book, and how I can create that
map on page 19-10? Thanks.
