I have a MapCache <-> MapServer setup and running. MapCache is configured for WMS access and is used to cache tiles for specific layers provided by my MapServer. I can access the WMS capabilities and display a tile through my browser by accessing WMS trough MapCache and have verified that it is being cached.

Excellent, just what I wanted.

Next, I setup a WorldWind client to access the MapCache WMS. WorldWind complains that the rootlayer (something MapCache uses to wrap all layers) does not provide a geographic bounding box. WorldWind logs this as severe and starts throwing exceptions. I'm trying to figure out where the problem lies. Does the WMS OGC Standard require the top layer to have a bounding box or is the WorldWind client not WMS compliant? Below is the error messages that I'm seeing. Below that is the getCapabilities response. Below that is the MapCache xml file. Below that is the MapServer map file.

Any help will be greatly appreciated.

Exceptions:

I know this is old, but I too am having this problem. I have loaded up a server on the WMS World Wind example and it recognises all the layers there. But every single layer I click to add it gives me the " SEVERE: No geographic bounding box given in WMS Capabilities for layer #"

Where # is the layer number i've tried to add. All layer's have the same problem. Now I have no problem loading this data in other mapping software (Global Mapper, or osgEarth, etc.). Just NasaWorld Wind.

The layers are TMS driven.

Any help would be greatly appreciated!

Hello,

I believe every named layer (what should be showing up in the layer list in the WMS World Wind Example) should have a Geographic Bounding Box (see WMS 1.3.0 section 7.2.4.6.6). Would you mind posting the GetCapabilities document for your server? That would help track this down.

Thanks,

Zach

I am not an expert in these areas, so I'm not sure I did this fully correctly. But here is what I believe is the WMS GetCapabilities document for my server. (Just change the extension from .txt to .xml)

Regards,
David

David,

Thanks for the example GetCapabilities document. After a quick review, I'm not seeing the WMS 1.1.1 required "LatLonBoundingBox" element (see section 7.1.4.5.6). I'm not sure why the other clients you mentioned work without that particular element, but it is used by World Wind, and therefore the layers are not being displayed. If you can update your server to provide that element, along with any other specification required elements, please let us know if you find any additional issues.

Zach

Thanks for the help Zach I will look into that element then !
