Online Data Sources

The Add Data hub's online path (see Importing Data) can pull directly from a catalog of online sources, organized into six categories. Selecting a dataset opens its own guided import steps, tailored to what that source needs (an area of interest, a set of measures, a time range, and so on).

This page catalogs what's available in each category. For how the import wizard itself works, see Importing Data.
