- Worth noticing
- A publication manifest is designed to record the configuration hash, source datasets, and a SHA-256 checksum for every output.
Field notes
The route planner lists 40 ports, with canal and ice-zone options, and says it includes time at the selected speed plus wind, waves, and daylight along the route. Analysis centers on a Cambridge Bay study boundary that the project explicitly distinguishes from an administrative boundary. The page says those layers currently use synthetic data; its described publication workflow records configuration and dataset details alongside checksums.
