QTH file altitude as absolute altitude instead of AGL

[KyleMaas]

It would be really handy if I could specify transmitter sites using absolute height data (which I already have) instead of having to find the average ground level of the site and subtract it to get an AGL value.

We should really overhaul the whole way the terrain data is handled - the preprocessing is sort of silly considering the kind of CPU horsepower even the dinkiest computer has these days. As for your particular request, maybe we can have some extra field that declares that you're defining it as AGL vs MSL.
