California's Sea-Change Tool Cabinet

- Worth noticing
- The comparison table covers scope, process, exposure, data, and known limitations, with comparisons of up to three tools.
Field notes
The atlas separates geographic exploration from resource selection: its Leaflet map focuses on layers and scenarios for a particular stretch of coast, while the comparison interface evaluates candidate tools across scope, process, exposure, data, and limitations. The project says the map covers resources with publicly accessible endpoints rather than every resource in its broader list. It is explicitly under active development, and the homepage notes that some material may not yet have been verified by a human.
