[Geomoose-users] NFHL WMS from mapfile

[Dan Little]

Given the email I just got from Elizabeth and looking at the results of shp2img 
(from Brent's email), I would bet serious money (like $20 or a couple cases of 
beer) that MapServer is trying to request an image greater than 1024 x 1024. 
 This is causing MapServer to get an invalid response and returning a blank 
image.

Tell GeoMOOSE to tile the layer and see if you start getting reasonable results.
