There is a growing global movement towards open data – driven by a need to increase transparency, encourage innovation and enable greater insights.
This feature of ArcGIS Online allows you to find public data for your GIS and share your own authoritative data with the public – helping to build an open data community.
All vector datasets are automatically available for download as CSV, KML and Shapefiles, and are accessible via the GeoJSON and GeoService APIs.
Discovering open data
ArcGIS Open Data provides public access to open data directly from the source. Discover map, feature and image services, spreadsheets and tables, and even web apps and documents. Search and download entire datasets or a filtered subset in a variety of data formats, or access it dynamically via an API.More
Sharing open data
ArcGIS Open Data uses the ArcGIS Online groups already available to identify open data, allowing you to quickly publish or remove any open data. Your open datasets automatically sync with the latest version of your sources. They can even integrate with other open data platforms such as CKAN.More
ArcGIS makes it easy to integrate OpenStreetMap (OSM) data into your maps and apps. OpenStreetMap is an open, collaborative project designed to create a free, editable map of the world. Volunteers gather and upload location data using GPS, local knowledge, and other free sources of information.
