IndianaMap publishes 840 open datasets for United States. Browse them live in Vizzie and turn any one into a map or chart.
IndianaMap is the open-data portal for United States, covering Indiana. It runs on ArcGIS Hub, Esri's open-data platform for geographic data. You can browse it directly at www.indianamap.org.
On IndianaMap, a majority of datasets here declare no licence at all. It's important to know that "no licence declared" is not the same as public-domain or free-to-use. Undeclared data carries no explicit permission to copy, adapt, or redistribute it — so reusers should treat it cautiously and check with the publisher before relying on it. Vizzie flags each dataset's licence (or its absence) so you can see this before you build.
Of the 51 datasets here whose licence Vizzie can identify, essentially all of them can be used commercially. Attribution is required by almost every open licence — Vizzie writes the attribution line for you when you export or publish.
The state's framework-data catalogue (IGIC/IU). 50 of 840 datasets declare a CC licence; the rest are warranty disclaimers (measured 2026-09-19).
