[Geomoose-users] WMS not working

Hello,

I have a question that is related to this topic

At GeoMOOSE 2.2 we could reproject rasters on the main map.  However, the reprojected rasters did not print.  Was this fixed at GeoMOOSE 2.6?   If it was not fixed, then I would recommend using MapServer to project the rasters.

Thanks

Yes, it is possible.  Just like other GIS/web mapping tools, the map display itself is set to be in a certain projection. Any source data (in this case WMS imagery) that is not in that coordinate system must be re-projected.  In the GeoMoose world this typically happens in one of two places; either in GeoMoose itself (where the web browser does the re-projection) or in MapServer.

In the later case, MapServer essentially acts as a WMS proxy. You would configure GeoMoose to use MapServer as the WMS source.  MapServer in turn is configured with a layer, which pulls from the "real" WMS server.  MapServer re-projects that data and punts it back in the native projection that GeoMoose expects.

Typically, if I want to pull in layers that are in multiple different projects I let MapServer do the heavy lifting in this manner.  I have played around with letting GeoMoose deal with multiple projections, but frankly I find it to be slower and just generally a bit more troublesome to configure and debug.  Others on the list may have a different experience.

Hope that clears things up rather than making them murkier ;)

Paul,

That worked!  Thanks for your help with this.  So, is it possible to use WMS layers that are in a different coordinate system, or is that not possible in GeoMOOSE?  I was looking at adding aerials that were originally in Dakota County Coordinates and in UTM coordinates.  Before I get to far into this I should find out if that is even possible or not.

Thanks!

Ah, ok.  I expect that's the problem.  The 3857 projection is for "Web Mercator", aka "Google Projection".  The MnGeo WMS service that you're trying to hit only provides imagery in UTM15N (26915).

However, there is a solution!  Try using the following.  The URL specified here serves the same imagery in the project that you need.

<map-source name="fsa2010" type="wms" projection='EPSG:3857'>
                <url>http://geoint.lmic.state.mn.us/cgi-bin/wmsll?</url>
                 <layer name="fsa2010" />
                <param name="TRANSPARENT" value="true"/>
                <param name="FORMAT" value="image/jpeg"/>
</map-source>

Is your mapbook.xml set to the same projection (26915)?

<param name="projection">EPSG:26915</param>

Sorry, I had copied that to post it, but switched it to "on" before I posted, nothing worked.  I deleted status all together, it is still not working.

Dennis,

At first glance, try removing the ' status="off" ' setting on the <layer>

I have been working with GeoMOOSE just a short time and am having issues with getting a WMS layer to display.

I have tried adding the WMS directly with and without a MAP file.

Here is what I have for the map source and layer in catalog:

<map-source name="fsa2010" type="wms" projection='EPSG:26915'>
                <url>http://geoint.lmic.state.mn.us/cgi-bin/wms?</url>
                 <layer name="fsa2010" status="off"/>
                <param name="TRANSPARENT" value="true"/>
                <param name="FORMAT" value="image/png"/>
</map-source>

<layer title="2010 FSA" src="fsa2010/fsa2010" status="off" legend="false" fade="false" unfade="false"/>

What am I doing wrong, I can't seem to find any of the solutions with online searches.
