As fi tare interesat de niste teste comparative serioase intre aceste date, si srtm. Si mai ales, intre acest aster gdem, si un dtm bine facut din 1:25k.. chiar si din 1:50k.
Din pacate nivelul meu de cunostinte in domeniu, precum si setul de unelte folosite, nu imi permit realizarea unui asemenea demers.
Ramane sa fiu recunoscator in avans celor care ar avea aceeasi curiozitate, dar si ceea ce trebuie pt a si-o satisface.
