I used my drone to get aerial imagery of the Dog River with my Norwich University students in Geology 110. Here they are collecting data and enjoying a warm September day. They are testing hypotheses that they derived on the relationship between river water depth, water velocity, and sediment size. And they got to use the drone images in their lab write-up!

Many thanks to NSF, Earth Cube, UNAVCO, and all the individuals who helped put on the workshop “Advancing the Analysis of High Resolution Topography.” It was great to share our work in this field, learn some new techniques, and discuss future directions for LiDAR, drones, and imagery. Truly wonderful.

It was a coincidence that in one session we used one of my previous field sites to practice PIV – particle image velocimetry.  In 2003, I measured stream flow emanating from several glaciers in the Dry Valleys in Antarctica. In the workshop, we used repeat LiDAR datasets of one of those glaciers, the Canada Glacier in Taylor Valley. Here are some of the images and results from our analysis. The bottom left (grey image with green arrows) shows  the direction and velocity of ice movement, that I derived using particle tracking code in MatLab.
