GeoWhisperer: Satellite Change, Read Cell by Cell
A browser tool for comparing dated satellite images of a place through swipes, side-by-side views, fades, movies, and downloadable reports.
- For
- Researchers, journalists, and geographic investigators
- Worth noticing
- Seven mechanical checks run before the cell-by-cell change reading, including season, capture date, resolution, and zoom.
Field notes
The workflow separates image hygiene from interpretation: the first pass checks paired imagery for duplicate dates, resolution mismatch, seasonal effects, capture records, zoom range, and visible place types. The second pass examines a fixed square by grid cell and requires each reported change to name what appears in both images. The stated source is Esri World Imagery Wayback, whose releases may be years apart and do not represent every image captured by satellites.
