Bruno -
Could you post the EXTENT statement you're using? Two
things to check - UNITS DD should be there (should not affect this problem,
however) and your EXTENT needs to be in the order MINX MINY MAXX MAXY, so it
should be:
EXTENT -48.0004159 -25.0004164 -46.5004159
-24.0004163
Your image is 1.5 degrees wide (X dimension) and 1 degree
tall (Y dimension) so your output image size should also be that shape (600
pixels wide by 400 pixels high, for example) or you will see the map shrunk to
fit the shape of the image.

I could take from it the EXTENT to use in my Mapfile using the Lower Left and Upper Right coordinates. But the problem is that the image is to small inside this coordinates and I can't find the image location inside then by this output. Is there some other utility to get this coordinates?
