How does this relate to NASA's NISAR StoryMap?

NASA's Land Subsidence StoryMap (Peacock et al. 2024, NISAR ArcGIS StoryMaps) explains how radar detects sinking from groundwater pumping, using the California Central Valley and the California Aqueduct as its example: NASA's airborne radar UAVSAR saw over 40 inches of subsidence in parts of a “subsidence bowl” between 2013 and 2017 (Miller et al. 2020, Remote Sensing of Environment 251, 112063; Jones et al. 2020). The StoryMap describes what NISAR will do. Our project is that next step with real 2026 NISAR data: the same valley measured from orbit, checked against GPS stations and a second satellite pass, and turned into a risk list for canals and roads.

How we used AI

Code, analysis scripts and text were written with the help of AI assistants (Anthropic Claude, Google Gemini) and checked by the team: every number comes from the data files, every scientific claim has a source, and tests cover the core conversions. The site uses no AI-generated images: every map and chart shows real measurements.
