[mapserver-users] GDAL not working perhaps

[Ed McNierney]

Isai -

That's a good test.  You don't have to specify any projection; if your sources and output are the same projection, things should work OK.  It's a little safer to specify the projections in my opinion, but not necessary.

I'm not sure your assumption about the images remaining visible is correct, depending on the rotation.  You might try making the extents much larger, but centered on the same spot, to see if the images are actually showing up in a slightly unexpected place.

Do I have to specify the projection type in the map file?  I am using UTM 
and here is part of the top of the map file

NAME GRID
EXTENT xxxx.xxxxx xxx.xxxx xxxx.xxxx xxxx.xxxx
STATUS ON
UNITS METERS
IMAGECOLOR 0 0 0

etc...

Is this sufficient for a map file heading?

Also:

Right now I just compiled again without the --without-tiff option (and with 
the --with-gdal option) just to make sure that the extents are right.  The 2 
images are now in almost the exact center (without rotation of course).  I 
believe the rotation has its axis in the top left corner so when the images 
rotate (in the future) I should still be able to see them without changing 
the extents again, right?

Thank you for the help.

Respectfully,
IML
