[mapserver-users] RE: mapserver-users Digest, Vol 28, Issue 46 (Re: WMS setup help)

[Kent Morrison]

Thanks for the response Jeff. That eleminated the error but I get blank tiles. When I look at the WMS using Gaia 3.4.2 I can see the image. Using mapserver I get blank tiles for the same area.

The mapserver log shows:
[Fri May 21 18:34:32 2010].534000 CGI Request 1 on process 2928

[Fri May 21 18:34:32 2010].565000 mapserv request processing time (loadmap not incl.): 0.031s

So it doesn't look like there are any errors.


Does anyone have a map file they used to access USGS WMS theat I can look at?

Thanks,
Kent

Hello Kent,

My guess is that you are missing the EXTENT parameter at the MAP object level.  In other words, copy the EXTENT line from your LAYER object, and place it after your FONTSET line.

I hope that helps.
