I recently learned the USGS has free aerial LiDAR data for many areas. Draw a box, then click the green button on the right side and select Eptium viewer. apps.nationalmap.gov/lidar-explor...

Also, I have quite a few videos that are soon to be released, but the perfectionist in me always causes me to wait, trying to add things, or improve things, thinking I can always make the video a little more interesting.

I'm looking forward to being a featured creator again at Open Sauce 2026. It's a really fun event that celebrates creativity and technical ability. July 17-19 at the San Mateo Event Center. Check it out! opensauce.com
