Tallahassee: City Time Machine
Watch the built-up surface of a city change. Explore historical GHSL snapshots within a fixed study window. Newly built-up surface appears between source epochs; cells do not date individual buildings.

- Fixed 40×40 km equal-area study windows aligned to GHSL cells; these are not municipal boundaries.
- 1 km source cells describe estimated built-up surface, not individual buildings or construction dates.
- 1975–2020 values combine satellite observations and modelling/interpolation. 2025 and 2030 projections are excluded.
- Presentation can blend cells between snapshots; numerical summaries always use the labelled source epoch.
- Local shoreline, classification uncertainty, and corrections can create decreases. Missing cells remain unknown.
