This dataset contains 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). This dataset is used for agricultural planning, as well as for a variety of applications in land use classification.
Data are stored in blobs (one blob per image) 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. Data is 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 the resolution; “1m” in all the data currently available in this container, but subject to change.
- Quadrangle: USGS quadrangle identifier, specifying a 7.5 minute x 7.5 minute area.
Files are stored as .mrf (Meta Raster Format) images (format spec), where each image is represented by three files: an .mrf metadata file in .xml format, a binary index (.idx) file, and a .lrc file containing the pixel data. These files were produced (from the original, USDA-provided GeoTIFF format) and organized by Esri. The .mrf format is both cloud-optimized and supported by GDAL.
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:

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 .txt file:
We also maintain a SQLite database to facilitate querying images by location and time; see the sample notebook for details.
