WHPC@SDSC Professional Speaker Series with Chelsea Scott and Cassandra Brigham from Arizona State University
Topographic differencing measures landscape change at the Earth’s surface due to natural and anthropogenic processes. OpenTopography, an NSF-funded data facility, provides access to topographic data and processing tools. OpenTopography has recently developed on-demand topographic differencing and uncertainty calculation tools that can be applied to roughly 25% of the US mainland. Our uncertainty tool, available via a cloud-based app and Jupyter notebook, quantifies the magnitude of uncertainty at multiple spatial scales, mirroring the variable scales of common error types. We demonstrate these capabilities by calculating topographic change for the 2025 Eaton and Palisades Fires in Los Angeles.
