Landsat surface reflectance data is hard for non-experts to access and use in the field

LLandsat satellites have measured Earth's surface reflectance for decades, but pulling the right data for a specific place and time still demands technical skill. The challenge asks for a tool that lets a user compare ground measurements to Landsat data on the fly, even from a phone in the field. Easier access would help researchers, students, and land managers act on satellite imagery.
