Is it possible to update HGT files with Locus? Are they updated at all? Or are there different sources for some countries with better resolution, and newer?
I was glacier trekking last week in Switzerland, and sometimes the actual altitude was more than 100m (!) below what Locus was showing me.
I realize that for probably 99.9% of the earth's surface, the altitude profile doesn't change significantly over the years - but glaciers are an exception, and unfortunately these days a big one.
Anyone knows anything about this?
