National Agriculture Imagery Program (NAIP)
The National Agriculture Imagery Program (NAIP) collects leaf-on (as opposed to the more common leaf-off) aerial imagery at 1 or 2 meter resolution for the United States. This imagery is used for estimating crop plantings and yields.
For North Carolina, imagery was taken and is available for the following growing seasons:
In 2004, 2005, and 2006, the data were released as a single mosaic for a county in MrSID format. Image file sizes are hundreds of megabytes - for example, Wake County's 2006 mosaic is 921 MB. Projection is UTM, NAD83, meters.
Web Mapping Services (WMS)
Instead of downloading the data, consider using WMS. The NC Department of Agriculture and Consumer Services has several WMS services open to the public with NAIP imagery, as well as DRGs and DOQQs. The full list is maintained on their webpage. NCSU Libraries has a WMS webpage with more details about using WMS.
NCSU affiliates (current faculty, staff, and students) may download the 2012 TIFF imagery from the Geodata Server at http://geodata.lib.ncsu.edu/NAIP. 2010 and earlier requires contacting Data Services.
Non-NCSU affiliates needing access to the recent CIR TIFFs may contact Data Services. Otherwise, for instructions to the NCDA&CS ftp server, contact Dan Madding with NC Dept. of Agriculture and Consumer Services, Emergency Programs Office - email: daniel.madding at ncagr.gov, phone: 919-807-4343.
