GraphClick - digitize points

mp told me about this one: GraphClick

http://www.arizona-software.ch/graphclick/

She is using it to digitize grain size distributions. I used it to digitize contours of the damage zone around Wenchuan earthquakes from historical documents and volume of continental crust through earth time curves. You need to pay the $8 to get all the features (like saving more than 10 points), but it is well worth it, and you can try it out before paying.

I LOVE useful software.

It is for mac only I think. sigh.
