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.
