I have a data set that maps more than one UTM zone (for example zone 15,16).
First,I considered to take the west most zone,but, I am not sure as this results on coordinates distortions,and as an UTM zone is considered as "flat" for 500Km only (as I know).
Moreover,I am not sure that if I reproject (to geographic) a point from the zone 16 (that was projected on the zone 15) that I will get the same result.
Any clear idea?
Thank you in advance.
