so It seems that recently(at least it's more recent than the WS2.0 release) USGS has released a global SRTM dataset with 1-arcsecond resolution(previous data was 1-arcsecond for USA only and 3-arcsecond for the rest of the world apparently)
so, is it of any relevance for us? can this new elevation data be used for building scenery for FG or would there be any issues(like licensing or bugs)
