More lidar experiments
I spent some time today playing around with lidar data and trying to learn how to get more out of it than just contours. Here are three images based on the "all returns" data from an area nearby. If you're familiar with Lawrence, you'll recognize McCollum Hall in the top left of the images.
For my previous lidar experiments, I've generated contours and used the intensity files (which is basically a fuzzy, black and white air photo). I think using the all-returns data gives me access to a lot more information.
Yes, I used OL Laser. I spent some time this morning testing different settings and images. I'm able to get a lot more information out of it than I'd been getting before (using QuickGrid to generate contours and the intensity images that were already created).
