2005 National Agriculture Imagery Program

Dataset Basics

The National Agriculture Imagery Program (NAIP) acquires imagery during the agricultural growing seasons in the continental U.S. The acquisition specifications for the Indiana 2005 NAIP imagery was a two meter ground sample distance (GSD) image that matches within 10 meters of reference ortho imagery. The imagery acquisition began July 1, 2005, and ended September 2, 2005.

NAIP imagery products are available either as quarter quad tiles in TIFF format or as compressed county mosaics (CCM) in MrSID format. The Farm Service Agency (FSA) created the compressed county mosaic product to provide timely information for the FSA compliance program. The FSA now considers each 2005 county mosaic from the ISDP archive to be a final product. Each county mosaic includes the full extent of an Indiana county, but also includes some surrounding black (no data) areas.

University Information Technology Services at Indiana University is working with IndianaView to acquire the TIFF dataset.
