Has anybody managed to use the SRTM 3 sec DTM ?
I have downloaded a couple of tiles (.HGT files) and have set up PL4 as described in the instructions but I have not yet been able to generate a profile. What an I doing wrong or is there a particular knack of which I am not aware ?

I have eventually found my error. Just be careful when downloading specific files as the numbering scheme for the northern hemisphere is different to that of the Southern.
From 0 degrees to 1 degree North the file is designated N00Exx, where on the 0 degree to 1 degree South it is designated S01Exx. So beware when downloading specific files or you may download the wrong one!!
