Teton Conservation District

Teton County, WY, Historic Aerial Imagery

TCD has worked with cooperators to locate original format aerial imagery of Teton County, WY, and develop it into Geographic Information System (GIS) layers.  Imagery has been located in areas ranging from federal archives in Maryland and Utah, as well as the National Park Service's Western Archeological and Conservation Center.  Our goal, accomplished in 2013, was to provide imagery of the county for every ten year period.

Aerial imagery has traditionally been available as contact prints and negatives.  Technology allows these formats to be transferred into a GIS or digital layer, where other data can be overlaid and analyzed.

Aero-Graphics, Inc., of Salt Lake City, has provided photogrammetric services to scan, orthorectify, and georeference our negatives and prints. 
GIS imagery has been produced for the following years:

1945 Greyscale  20 foot / pixel
1955 Greyscale  1.0 foot/ pixel
1967 Greyscale  1.5 foot / pixel
1977 Color  1.0 foot / pixel
1978 Greyscale  3.0 foot / pixel
1983 Infrared  3.0 foot / pixel
1989 Infrared  3.0 foot / pixel

Imagery is available in several formats:
1.  Imagery can be downloaded here.  Both indexes and individual tiles are available.  These files are large and may be slow to download.  Typically, they are used with GIS, CADD, or other professional software.

2.  Teton County Map Server.  Map viewers and services previously available on TCD’s web site have shifted to Teton County’s Map Server, located here. This site offers increased functionality and additional data layers that can be viewed in conjunction with the aerial imagery. This change now allows capacity such as measuring acreage of an area, or viewing imagery along with property boundaries and zoning overlays.

Future Imagery Projects

Teton Conservation District is continuously searching for additional aerial imagery, and is regularly improving existing data sets.

Sources of this imagery include National Archives and Records Administration (NARA) in College Park, Maryland, the United States Department of Agriculture- Farm Service Agency Aerial Photography Field Office (USDA-FSA APFO) in Salt Lake City, and the Western Archeological and Conservation Center of the National Park Service. 

Project cooperators include Grand Teton National Park, Bridger-Teton National Forest, Region 4 of the USFS, Grand Teton Association, Teton County, WY, and the National Elk Refuge.   

Teton Conservation District grants free and unrestricted use of the data on this site, but prohibits resale of the data.
