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 |

I think they had only a few colours - so they bracketed wide ranges of values with the same colour. You can see the pencil lines where they drew the areas that they then coloured in...... i think.

I looked again to the close up image where the numbers are visible. Here's what I could make out of it. I had to align some columns vertically because the printouts seem off by one or two rows at places. So here you have numbers to numbers
