GDAL Results Interpret for Australian Raster

[Nick Dabner]

Thanks Jacob.

As the path may have indicated. These are Ausways maps. I believe they
are in AMG66 format, although my associated vectors are in WGS84 so I
am told.
The map covers Adelaide to Brisbane which is potentially providing the
conflicting zone info you noted. I am personally in Melbourne.

How can you tell what zone - by the longitude? Would you use the
centroid as this is a large map?

regards, Nick
