Hmmm...missed that one. But changing the units to dd still doesn't have<br>
any effect.<br>

I am using mapserver 4.8.1. DEBUG is not an option in this version.<br>
mapserv -v produces the following output:<br>

Try changing the layer status to default, ie:<br>
<br>

I am having some problems adding a raster layer to my<br>
map. The<br>
image<br>
produced by mapserver is blank. My mapfile is as follows:<br>
<br>
MAP<br>
SIZE 800 600<br>
UNITS meters<br>
<br>
<br>
This is a problem, Your UNITs are meters, but your extents and<br>
projection are DD!<br>
<br>
<br>
EXTENT -123.8600311 38.0116386 -97.1885986<br>
53.7055626<br>
<br>
PROJECTION<br>
"+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs"<br>
END<br>
<br>
LAYER<br>
NAME "grid"<br>
TYPE RASTER<br>
DATA "/tmp/image.tiff"<br>
STATUS ON<br>
PROJECTION<br>
"+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs"<br>
END<br>
END<br>
END<br>
<br>
I have also noticed that changing the DATA path to a<br>
file which<br>
does not<br>
exist in the filesystem (or is not a GDAL-supported file<br>
format)<br>
has no<br>
effect on the rendered output and does not produce an<br>
error message.<br>
<br>
Can somebody help me where I am going wrong?<br>
<br>
Thanks<br>
