Indiana Statewide Digital Aerial Imagery Catalog

The Indiana Statewide Digital Aerial Imagery Catalog, hosted on the Registry of Open Data on AWS, offers a comprehensive collection of digital orthophotography for the State of Indiana. Managed by the Indiana Geographic Information Office and IOT Office of Technology, this valuable resource dates back to 2005, providing historical and current aerial views across the state.

Datasets are made available in Cloud Optimized GeoTIFF (COG) files, original GeoTIFF, and other compressed formats such as ECW and MrSID, ensuring accessibility for various geospatial applications. Each year's imagery is meticulously organized into a statewide tile grid scheme, with tiles named to reflect their lower-left coordinates, facilitating easy data discovery and integration.

The imagery collection follows a 4-year update cycle, divided into three regional "Tiers" covering Indiana from South to North. This systematic approach ensures regular updates for different parts of the state. All data is licensed under Creative Commons 0 (CC0), promoting broad public access and reuse.
