A little teaser, but look forward to some much improved performance with GDAL elevations once we merge our topic-fallback branch back into the master. With the changes in that branch I was able to load the entire CGIAR dataset which is 874 geotiffs, ~60 GB of elevation data, as separate layers in osgEarth and zoom around with no cache and data just flies in. I imagine the same can be said for the ASTER dataset but haven't played with it just yet.
We'll hopefully get things merged back to the master very soon and you can play, it's awesome ;) Jason On Tue, Feb 25, 2014 at 2:34 PM, Arthur Bogard <[email protected]>wrote: > I'll third the call for osgEarth.
