On-Demand 3D Topographic Differencing
By Chelsea Scott
Topographic Differencing Showcase
OpenTopography recently released on-demand vertical differencing. Here, we showcase a range of anthropogenic, geomorphic, and tectonic processes imaged using topographic differencing on OpenTopography’s portal. In each image, erosion or downward change of the Earth’s surface is colored in red, while deposition or upward change is colored in blue. We include a link to the change detection page for each dataset pair so you can run your own jobs and explore.
