Hi juamei

It would be interesting to see the difference between 1m resolution, 0.5m and 0.2m for the same site.

I'm not really sure what resolution the ones up here are.

Learning python is taking it up a level or 3!

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.
