Other WMS Clients

A Sampling of Web Map Server (WMS) Clients From Other Sources

TNTserver is one of a growing number of Web Map Services that provide geodata to WMS clients across the web.  TNTserver is carefully engineered to conform to the protocols of the WMS standard defined in the Open Geospatial Consortium (OGC) specifications 1.3.0 and 1.1.0.

TNTmap can combine map layers from many WMS sources.  However, as with any new technology that depends on sharing protocols, an uneven implementation of features can be expected among servers and clients.  A particular WMS server might be temporarily offline

• You may have problems with a map client that does not correctly access and display layers from a WMS host.  It might not be able to handle map layers from multiple hosts or in different coordinate reference systems.
• You may have problems with a WMS source that does not correctly respond to requests from your map client.  It could be offline, unable to handle heavy demand, or it might not be able to understand the map client's request.

If TNTmap doesn't retrieve a map layer correctly from some WMS site, first see if you can get correct results by using one of the other clients listed below.  If you get correct results there, then please share the details of your tests with us so that we can make the TNT products the most dependable and robust on the web.

Since the two clients shown below use Lat/Lon instead of the map projection associated with the geodata, the overlay shows with a rectilinear aspect.  Compare that with the correct curved aspect of the clients above, which correctly render the map projection:
Google Earth	NASA WorldWind

Try TNTmap.  If you observe problems with TNTmap, try loading the same layers with some other WMS client.
