WSClient_Display WMS overview image as WMSLayer in WebWorldWind

[Bang Pham Huu]

Current, WSClient sends 1 GetMap request for the default WMS overview. It works fine with small coverage but cannot work with big coverage. It needs to be changed to use WMSLayer in WebWorldWind as WMS client will split into multiple GetMap requests which servers can process in parallel.

or it could try to calculate a small subset e.g. in the center based on the resolution for this single GetMap request.

From WSClient, it doesn't know the coverage's resolution and a small subset is too vague.

[Dimitar Misev]

A small subset would be something of say max 600x600px. But if resolution is unknown (you can't get this from DescribeCoverage?) then this can't work I guess.

ok, so let's just change to WMSLayer.

I'd argue that the sample GetMap request that is shown on the WMS tab is still nice to have, e.g. for manual testing?

yes, it is still the same, only change is instead of using SurfaceImageLayer in WebWorldWind, it uses WMSLayer.
