I'm pretty sure that gdal_translate here is using the .hdr and .prj
files - otherwise where is the location information coming from? The
hgt file has nothing in it other than the grid of values, and the
location information is purely found in the name of the hgt file and
the (external) maths required to convert that into coordinates.
