Troubles & Questions / Dynamic Elevation: Method of determining elevation using .hgt-Files
« on: June 30, 2016, 18:25:08 »
I'm experimenting in producing more accurate .hgt elevation files compared to the ones downloaded with Locus especially for mountain terrain in Austria.
For example there'e a mountain peak with true elevation=1206 m
The highest peak of this mountain in the original .hgt-file of Locus=1185 m
The highest peak of my new created .hgt-file of this mountain=1206 m
But now the strange thing: When using my new .hgt-file in Locus, the map show me a maximum of 1210 m at the location of the peak. How can this be, since the highest spot in the .hgt file is 1206 m and each point on the map should be <=1206 m?
What method of filter is Locus using to calculate the high at the exact cursor's location out of the elevation-values around this location of .hgt-file?
