I assume it is the same to determine the latitude zone (using 8
degrees). The one thing though are the exceptions (even though I don't
intend to do any computations in those zones) ... . Is it correct then
to assume that gdal has no capabilities to return the zone based on a
given lat/lon pair? As easy as the code you provided is, it seems that
this capability (and the zone exception handling) would be included in
gdal ... .

either way, thanks
