Abstract:
Black and White aerial photos of the Yellowstone River floodplain between Reed Point and Custer, Montana. These photos have been georeferenced and rectified, but they have NOT been orthorectified. The photos may be used to see what the area of the photograph looked like in general, but should NOT be used to determine the location of any object that can be seen on the photos. The photos were taken on June 14, 1997, two days after the peak flood stage of 15 feet on the Yellowstone River in Billings. The first set consists of 29 mosaics arranged so that the white no-data areas from adjacent images do not obscure each other. The images have been resampled to a horizontal resolution of 0.4572 meters, or 1.5 feet. The second set of images are 69 individual aerial photos, and their resolutions vary from 0.356 meters to 0.496 meters (14 to 20 inches).
Purpose:
These images were created for the Yellowstone River Conservation Districts Council, to support understanding of the Yellowstone River floodplain, including hydraulic floodplain delineation, planimetric data extraction, and as a base map for monitoring long-term river channel changes.

Title: Aerial Photography
Source scale denominator: 24000
Type of source media: filmstrip
Source contribution:
The photography was flown at an altitude of 12,000 feet above mean terrain. The camera was a 6" focal length Zeis RMK TOP15, equipped with forward motion compensation and Gryo Mount. The film was Kodak 2405 Black and White film
Calendar date: 06/14/1997

Process step:
The film was scanned by Z/I Imaging PhotoScan scanning workstations operating under Photoscan (tm) and Autoscan (tm) software. The scanning resolution was 14 microns, or 1813 dots per inch, resulting in an approximate ground resolution of approximately 13 inches.
