Currently the 7 zones are stacked left to right.
I quickly hacked up a right to left stack:
tms url is: http://a.agri.openstreetmap.org/rtl/{zoom}/{x}/{y}.png

There are a few regions which are better but not a huge amounts. Some
regions better, some worse.

I received help converting the ground control database from ArcGIS
File Geodatabase to CSV:
 CSV is here: http://agri.openstreetmap.org/download/AGRI_GCP/AGRI_GCP.gdb.csv

The first column + Folder column link to the photos/sketches here:

 Example Sketch:

Maybe someone wants to create a OpenLayers webapp with the
photo/sketches geolocated using the above CSV? Or maybe adding EXIF
Geo data to the images?

My next task is working on the South African 0.5m colour imagery I
received from the "Chief Directorate: National Geo-spatial
Information" (South African national mapping agency).
Maybe GeoScience Australia has similar imagery?
