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.

WMS

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:

1. Go to the list of available imagery layers and click the link for the imagery you want.
2. From that page, click the link that says "WMS." The URL of this page is the link you want to add in JOSM.
3. Next, add that link in JOSM:
   1. Open JOSM's imagery preferences and add a new WMS layer.
   2. In the service URL box, paste the link to the desired imagery.
   3. Click "Get Layers" and select the layer that appears.
   4. Select image/jpeg for the image format.
   5. Press "OK."

Alternate instructions from Simon Legner are available here.

MapQuest

MapQuest has their OpenAerial tileset, mostly based on NAIP imagery. It's not necessarily the latest imagery;

A JOSM-format URL:

Telascience

As of May 2011, final 2010 imagery is available and is also accessible via:

  http://cube.telascience.org/tilecache/tilecache.py/NAIP_ALL/{zoom}/{x}/{y}.png

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).

Raw

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.
