gdalinfo v1.6.3 is incorrectly reading the georeferencing on pix files in UTM zones

[abarton]

It appears that gdalinfo v1.6.3 is incorrectly reading the georeferencing on pix files in UTM zones. Specifially the false northing is coming across as 10,000,000 instead of 0 and placing it in the southern hemisphere.

A sample can be found at ftp.i3.com using the fwarmerdam login. It is named georeferencing_sample.pix.zip.

This appears to be a problem introduced in r18096 by Phil in an attempt to provide interpretation of MGRS codes to indicate southern hemisphere. In this case the string is "UTM 13 D000" and ' ' is picked up as the MGRS code and misinterpreted as being southern hemisphere since it is not northern hemisphere.

This problem affects 1.6.3 and 1.7.0 both old and new PCIDSK drivers.

I believe I have corrected it in trunk (r18730), 1.7 (r18731), 1.6 (r18732), and 1.6-esri (r18733).

Phil could you review the change? I simplified the code quite a bit assuming that PCI strings from files are well formed, and that the MGRS zone code would always be in position 10 if set.

After a bit more discussion with Phil, I have applied a small fix in trunk (r18735) that makes the MGRS zone interpretation a bit more resilient in the case where something not intended to be an MGRS code gets picked up as an MGRS code.
