Yes that's right, thanks once again for all your help back then. We are still using the PI-3000 s/w too, in the training material we saw it seemed that maintaining a uniform above-the-surface-distance was important, so we have always used at least a monopod to ensure this, but it sounds as though we are being too cautious.
I'll make this one my last comment, because Ive drifted off topic (sorry folks, my fault).If you apply a 10-15% tolerance to the guidelines on focal distance, camera angles etc you'll still get excellent results. We broke so many photogrammetric rules on NADRAP but proved the robustness of the technique.
If you'd like to drop me another line, then please feel free.
cheers
