I've got a few .tab's from the PHX Lidar

Basically - after playing with it for a while, I'll end up with a spreadsheet of values. Each column being one sample 30s apart - each row being a different altitude.

Does anyone know a means of taking a CSV or similar, and turning it into a small image with pixel brightness representing the values from the CSV?

I've thought of one technique using conditional formatting in Excel - but it probably wont work very well

Next step - doing it greyscale - for the two different frequencies sampled. Then merge as R and G in a colour image to highlight differences.

Actually http://www.nasa.gov/mission_pages/phoenix/...plotTV_001.html - using THAT data set is probably a sensible next step.
