WMTS support

Hi All,

Several years ago, someone asked about WMTS support.  At the time, no one was really using it, but these days, it's much more heavily used.

For example, the NASA Worldview platform uses it: https://worldview.earthdata.nasa.gov

I think it would really be a boon for osgEarth to support time-series WMTS data like that from Worldview.  It opens up literally hundreds of datasets instantaneously to the platform.

Any thoughts or plans for it?  Here's the spec: https://www.opengeospatial.org/standards/wmts

Hi Arthur,

I agree that WMTS would be a useful addition and it's something we would certainly add if a sponsor comes along. General support for time-series data is sort of an orthogonal topic - also very useful and doing it "right" requires some additional thought.
