The statewide 2012 imagery from the National Agriculture Imagery Program (NAIP) is available from the GIS Hub and from the U.S. Department of Agriculture Geospatial Data Gateway. This 1-meter pixel resolution aerial photography is in MrSID format, organized by county.
To download the data from the GIS Hub, visit the Hub Data Portal then either browse within the Imagery category or simply type in 2012 in the What? field and click the Search button. Click on the More Information button then scroll down to the Transfer Options section and click on the "Download USDA-FSA-APFO Aerial Photography 2012 MrSIDs" link.
Please note that in early 2013 we plan to receive the 2012 imagery in a format that we can use to build a statewide mosaic that will be available as web services.
