Problem with raster layer

cristhiano
Hi everybody!
Could someone help me!

Mapserver is not rendering the raster layer, the others are OK. I´ve tried several ways to resolve this, but nothing.
The file sint_123.png is associated with sint_123.wld (georreference).

The sint_123.wld is like this:

30
0.0000000000
0.0000000000
-30
-54.126061
-29.600353



The mapfile is like this:

MAP

Cristhiano,

Note that your world file indicates a pixel size of 30 degrees by
30 degrees, so your map extent is covered by a fraction of the first
pixel.

If you mean the pixels to be 30 meters by 30 meters you could try replacing
30 and -30 with 0.00027 and -0.00027 and see if it is roughly right.  But
you should likely review exactly where you think this raster file is in the
world.

Best regards,
--
