How sitthisakmoukomla/s2dr4 works
S2DR4 is a notebook-driven Sentinel-2 super-resolution product. A user supplies coordinates and a date; the notebook obtains imagery, preprocesses it, downloads and applies the deep-learning model, then postprocesses results into four 1 m/px products. The documented workflow also includes radiometric and spectral preservation concerns, global Earth Engine acquisition, and optional interactive viewing. No source excerpts were provided, so relationships are limited to the README’s explicit three-stage workflow and documented outputs.
