National Agriculture Imagery Program (NAIP)
Overview | NCSU Access | Public Access
Overview
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:
- 2004 - incomplete statewide, 2 meter resolution
- 2005 - complete statewide, 1 meter resolution
- 2006 - complete statewide, 1 meter resolution
- 2008 - complete statewide, 1 meter resolution
Available as single county mosaic or in much smaller DOQQ tiles
- 2008 - Catawba River Basin, 1 meter resolution, includes color-infrared band (contact Data Services for access.)
Except for what's noted above, the data are 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.
Sources for NAIP imagery vary, depending on the location needed. For North Carolina, an ftp server is available for downloading the files.
NCSU Access
NCSU affiliates (current faculty, staff, and students) may contact Data Services for ftp access instructions. Sometimes the login/password is changed, so contact Data Services for updates as well if you can no longer connect. Copies of the images are also archived by the Libraries.
Public Access
Non-NCSU affiliates needing access instructions to the NC ftp server will need to contact Dan Madding with NC Dept. of Agriculture and Consumer Services, Emergency Programs Office - email: daniel.madding at ncagr.gov, phone: 919-807-4343.
NAIP imagery may also be freely downloaded for any US location from the USDA Geospatial Data Gateway. The USDA has brief instructions here.
