National Agriculture Imagery Program
The National Agriculture Imagery Program (NAIP) is a government program run by the US Department of Agriculture's Farm Service Agency that provides 1-meter aerial imagery covering the United States. The "leaf on" imagery is collected during agriculture growing seasons. NAIP imagery is useful because it is frequently newer than other easily-available imagery (like Mapbox and Bing) and can therefore be used for mapping recent changes.
In some areas (at least parts of Texas) Bing serves NAIP imagery.
Note: The instructions in this section no longer work.
NAIP can be accessed directly from the USDA's WMS; however, there are multiple services (one per state, excluding Alaska and Hawaii). Each state's link is listed at https://gis.apfo.usda.gov/arcgis/rest/services/NAIP.
To use NAIP imagery in JOSM:
- Go to the list of available imagery layers and click the link for the imagery you want.
- From that page, click the link that says "WMS." The URL of this page is the link you want to add in JOSM.
- Next, add that link in JOSM:
- Open JOSM's imagery preferences and add a new WMS layer.
- In the service URL box, paste the link to the desired imagery.
- Click "Get Layers" and select the layer that appears.
- Select image/jpeg for the image format.
- Press "OK."
Alternate instructions from Simon Legner are available here.

As of May 2011, final 2010 imagery is available and is also accessible via:
This is not always the latest imagery (example: the official NAIP server and MapQuest show more progress than Telascience on the US 54 expressway at Osage Beach, Missouri).
The USDA's Geospatial Data Gateway makes available downloadable county-wide image mosaics of NAIP imagery, other DOQs, DRGs, etc. Unfortunately, they are distributed in proprietary formats (MrSID, JPEG2000) and will require involved conversion before use in most software.
