You have a very goog product named WebGlEarth. But....
have some picture .png (may be .jpg) and I don't want to overlay it as
map with MapTiler. But I have to do it as a WE.poligon, for example. Can
I do it in WebGlEarth as in GoogleMaps API (simple overlay)? May be, you are planning
now to add this the same tool in the nearest future?
Thanks in advance for your answer.
