Sources of Aerial Imagery:

Federal agencies such as the United State Geological Survey and the U.S. Department of Agriculture Aerial Photography Field Office distribute medium resolution imagery products. These are typically available for download in tiles or are hosted as seamless GIS services like the ones we used in Lessons 2 and 3. State and Local governments often collect and distribute their own high resolution, time series imagery products. These datasets can be distributed on websites similar to federal imagery products. They may be a fee to access these products, or you may need to contact the organization directly to obtain them. There are also private companies that collect high-resolution imagery which they make available for sale.

  • United States Geological Survey Earth Explorer
  • United States Geological Survey (USGS):
  • USDA Aerial Photography Field Office (APFO) National Aerial Imagery Program (NAIP):
  • ArcGIS Online Data Services. Map tab> Add Data > Data > ArcGIS Online Portal. Search for “Imagery.” - compiled from a variety of sources.
  • Google Earth: If you zoom in close enough, you will eventually see an “Imagery Date” and “Source” listed at the bottom of the viewer. This is helpful for identifying local imagery sources that may not be listed in other clearinghouses (that’s actually how I found the Ohio Statewide Imagery Program).
