This file contains 10 images from 1938 and 79 images from 1949 for Todd County, SD.

The photos are from Todd (1938 and 1949) County, SD. No index map was prepared for the photos. The scale of the original photos was 1:20,000 or 3.17 inches = 1 mile. The inventory of images does not represent coverage of the entire county. The 89 images contained in this file represent the air photo collection for Todd County, SD that the South Dakota State University (SDSU) Pedology Project had on March 2004.
The structure of the files is as follows:

  1. There is a file folder for the county (e.g., Todd).
  2. Within the county folder there is a folder for the year and month of the air photos (e.g., 1938Jul).
  3. Within the year folder there are files for each photo scanned. The images are identified by the code used on the original photo/image. There is a county ID, a flight ID, and a photo ID on each air photo and that is what was used to name the image (e.g., BOL-37-205).
  4. Where possible, the original photo ID information was scanned with the photo (top of the image).
  5. Where more than one scan of an image was needed to scan all the image, the image ID was followed by an additional set of letters to indicate what part of the image the scan represents (e.g., BOL-37-210BTM = bottom of image BOL-37-210).
  6. Todd County, SD photo code – BOL.
