Fascinating project, and congratulations on such a good result.

 

It would be interesting to know how the overlay of the photo on the map works.

Thanks Anthony.

I'm not sure about that either and am not privy to what the NT have in mind.

It is probably being geo-referenced into a geographical information system (GIS).  Basically you match known points on the photo with points on the map and then let the computer do its work twisting and stretching the photo over the map.  Mathematically, it is similar to the distortion corrections available in our photo editors. The challenge for a project like this is deciding which corrections to apply and if, after all the corrections, the result is valid.  I'm guessing that getting boundaries within 2-3 metres would be a success for this given that the old map was photographed hanging from the wall.  The project is probably more about "field 1 & field 2 were combined and field 4 was sub-divided". Why & when did this happen?

 

Another interesting challenge would be to go back and photograph it in infrared or ultra violet, but finding appropriate light sources may be difficult.

The whole process is a bit hit and miss given that the map was hand drawn in 1580 and there is undoubtedly more than a little artistic licence in play. I suspect that more information will be gathered from side by side inspection and interpretation of geographical features.

We have to bear in mind that most of the detail within the original has not been inspected by the current staff given the severe restrictions on accessing the map (both physical and regulatory) so they are already learning so much from being able to inspect it in minute detail.

It will nevertheless be interesting to see if they use more sophisticated techniques.

As tempting as it might be, I'm not sure I want to go back and repeat the excise with different light sources. It took six months to get permission this time around!
