[Mapserver-users] Error using two terraserver WMS layers

[Dylan Keon]

Hi all,

I'm getting an error when using two Terraserver WMS ortho layers:

   PHP Warning:  [MapServer Error]: msDrawMap(): Failed to draw layer
   named 'ortho-11'. in /www/test.php on line 57
   PHP Warning:  [MapServer Error]: msDrawRaster(): Unrecognized or
   unsupported image format in /www/test.php on line 57
   PHP Warning:  [MapServer Error]: drawEPP():
   /www/temp/107187187367791.img.tmp is not an EPPL
   file. in /www/test.php on line 57

My WMS layers are ortho-10 (UTM 10) and ortho-11 (UTM 11).  The error is 
always with layer ortho-11, never with ortho-10.  In addition to this 
error I'm also getting inconsistent behavior such as occasional blue 
images in place of the ortho.  Here's a summary:

* ortho-10 ON, ortho-11 ON, zoom to ortho-10, get above error
* ortho-10 ON, ortho-11 ON, zoom to ortho-11, works fine
* ortho-10 OFF, ortho-11 ON, zoom to ortho-10, get above error
* ortho-10 OFF, ortho-11 ON, zoom to ortho-11, works fine
* ortho-10 ON, ortho-11 OFF, zoom to ortho-10, works fine
* ortho-10 ON, ortho-11 OFF, zoom to ortho-11, get light blue image

The archives show that others have had similar problems, but there 
didn't seem to be a resolution.  Anyone have suggestions?  My mapfile is 
below.  Thanks.
