ArcGIS Hub

Find and use the open data that cities, counties, states and organisations publish on ArcGIS Hub: search datasets across all Hub sites or one site, read a dataset's details and download links, and pull, filter, map and summarise its records. No account or API key is required.

Actions

Action	What it does
Find open data sites	Find the ArcGIS Hub sites (open data portals) of a city, county, state or organisation, with each site's address.
Find records near a location	Find a dataset's records at a point or within a distance of it, nearest first: which zoning district or parcel a spot is in, or the incidents, stops or facilities around it.
Get dataset details	Get a dataset's description, publisher, licence, fields, number of records and download links (CSV, GeoJSON, shapefile and KML).
Get records	Pull a dataset's records (its rows), filtered by a field value, a date range or an advanced filter, sorted and with only the fields you choose.
Search datasets	Search the open data published on ArcGIS Hub by governments and organisations, across all Hub sites or within one, such as opendata.dc.gov.
Summarize records	Count a dataset's records, or total, average or find the smallest or largest value of a field, overall or for each value of another field (for example, incidents per ward).
