Aye, even finding the lidar is a bit slow to do for every site, but I might be able to do a diff between 1m and 0.5m for Avebury. There doesnt seem to be much 0.2m about.
Re python, I'm a developer by trade (though more manager now), so another language on top of the 4 or 5 I am reasonably proficient in isnt too worrying for me.
