Aerial imagery from the National Agricultural Imagery Program (NAIP).
NAIP provides US-wide, high-resolution aerial imagery. This program is administered by the Aerial Field Photography Office (AFPO) within the US Department of Agriculture (USDA). Data are available from 2010 to the present.
Data are stored in cloud-optimized GeoTIFF files in Azure Blob Storage in the East US data center, in the following blob container:
Within that container, data are organized according to:
More details on these fields:
- Year: Four-digit year. Images are collected in each state every 3-5 years, with any given year containing some (but not all) states. For example, Alabama has data in 2011 and 2013, but not in 2012, while California has data in 2012, but not 2011 or 2013. Esri provides information about NAIP coverage in their interactive NAIP annual coverage map.
- State: Two-letter state code.
- Resolution: String specification of image resolution, which has varied throughout NAIP’s history. Depending on year and state, this may be “050cm”, “060cm”, or “100cm”.
- Quadrangle: USGS quadrangle identifier, specifying a 7.5 minute x 7.5 minute area.
Small thumbnails are also available for each image; substitute “.tif” with “.200.jpg” to retrieve the thumbnail. For example:
A complete Python example of accessing and plotting a NAIP image is available in the notebook provided under “data access”.
We also provide a read-only SAS (shared access signature) token to allow access to NAIP data via, e.g., BlobFuse, which allows you to mount blob containers as drives:
Mounting instructions for Linux are here.
NAIP data can consume hundreds of terabytes, so large-scale processing is best performed in the East US Azure data center, where the images are stored. If you are using NAIP data for environmental science applications, consider applying for an AI for Earth grant to support your compute requirements.
A list of all NAIP files is available here, as a zipped .csv file:
We also maintain an rtree object to facilitate spatial queries for Python users; see the sample notebook for details.
Data can also be browsed here.
Where did the .mrf files go?
In June of 2020, we updated our entire NAIP archive to improve both coverage and maintainability. We also switched from .mrf format to cloud-optimized GeoTIFF, and made some changes to path structures. The .mrf files are temporarily still available in another container; if they are important to your work and you need access, contact
