Access

Every endpoint this dataset can be reached through, grouped by how you would use it. Each name is the link; the copy button beside it copies the address. Everything is in the release record and was answered when the release was cut.

Apps that read this dataset from the release. The icons after a name are the app’s lenses — the spatial grain it shows the data at.
