[Mapserver-users] Max image size

[Swaminathan, Gayathri]

Ed,

Is there a way to log the WMS requests?

Also I missed to include the site address this is happening in my last mail.

It is http://129.15.172.20/okstatedemo40.htm

If you zoom into Oklahoma city area( the center of the state) and keep
zooming in., you will see the white line behavior after a certain scale.

Thanks for all your help and time on this.

Gayathri -

I'm always a little worried when the Metadata document describes the imagery
as UTM NAD83 and the Capabilities document declares it to be geographic!

Have you tried simply pulling up some images in a Web browser with
hand-coded WMS requests?  That ought to give you a better sense of what the
data's really doing.

Hi:

I am trying to project the USGS urban orthos at
http://gisdata.usgs.net/mapservices.asp?CategoryName=Orthoimagery using
mapserver version 4.

My map projection is in America Albers Equal Area Conic

And the WMS layer request is in WGS 84. 

The initial hurdle of the map image getting squished was overcome with the
help of Brian's advice to do REASPECT=false at the end of the request
string.

But there is a white band that still appears after zooming in over a certain
scale. 

We are not sure if this is a WGS84->Albers problem or else.

Has anyone else come across this problem? We really love albers projection
for the map. 

Thanks,
Gayathri
