[Geomoose-users] NFHL WMS from mapfile

I tried your map file and it works for me http://dev.houstoneng.net/geomoose.html – using this as the map-source:
<map-source name="flood" type="mapserver" tiled="true" >
<file>./demo/landrecords/flood.map</file>
<layer name="Flood Data Availability"/>
</map-source>
Generally if there are no error messages or pink screens, the issue is in the Mapbook - like the map-source/layer does not match in the catalog.

I put tiled=”true” in the map-source and still get nothing. I’ve also tried resizing the browser window to see if that made a difference for Geomoose but it didn’t.

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.

No, no pink screen. Just nothing.

Are you getting a Pink Screen of Death in GeoMOOSE? If the image is blank then I would be that MapServer is trying to request an image larger than the restricted size (1024x1024).

Here is the map-source from the mapbook:
<map-source name="fema" type="mapserver" tiled="false" reference="false">
<file>/ms4w/apps/metrogis/maps/mapfiles_metro/WMS/fema_wms.map</file>
<layer name="Flood Data Availability"/>
</map-source>
And in the catalog portion of the mapbook:
http://msc.fema.gov
I should also add that there are scale restrictions on the various layers in the service, but I have tried various layers and can’t get any of them to work. “Flood Data Availability” may not have been the best example to use here because it does not display at large scales (larger than 1:300,000).
Also, the service is not tiled and the maximum image size is 1024 x 1024 pixels. ArcMap is able to bring it in and it displays correctly.
I can get the service to display in Geomoose if I reference it directly from the mapbook but I would like to use a mapfile and bring it in that way. If I pull it in directly in the mapbook this works:
<map-source name="fema" type="wms" tiled="false" reference="false" projection="EPSG:4326">
http://hazards.fema.gov/wmsconnector/wmsconnector/Servlet/NFHL?
<layer name="Flood_Hazard_Zones_General"/>
<layer name="Q3 Flood Hazards (red)"/>
<layer name="Floodways"/>
<param name="format" value="image/jpeg"/>
<param name="TRANSPARENT" value="TRUE"/>
<param name="styles" value=""/>
</map-source>

Can you attach the Mapbook? or Copy and paste the mapbook entry that pertains to the WMS?

I have not been able to bring in the FEMA NFHL Flood Mapping WMS into my Geomoose map via a mapfile. What am I missing? Can anyone help??? Here is my mapfile. I have tried both “Flood Data Availability” and “HDM:Q3_COUNTYMAP” as the wms_name, and have tried calling both from the map-source in the mapbook file. Maybe there is a problem with the extent?
Thank you for any help.
