Dear Users,
I'm trying to understand how to create the hdr file for the .bil srtm
dem I downloaded....
I have found too much different information... so I try with you....:
if I have a N11E044.hgt file I have to rename the file to  N11E044.bil
and then to create a N44E011.hdr file...
can you help me to insert the right value in the ULXMAP and ULYMAP
sections of the hdr file below.... ???
