This image file (DS1104-1043DF002_2c.tif) was initially captured during the CORONA J-1, KH-4a reconnaissance missions and represents one of four image frames associated with a single swath which provides a nominal ground coverage of 17 x 232 km. This CORONA image’s ground coverage is approximately 17 x 38 km. This is attributed to cropping about one-third (20 km) of the image’s eastern extent due to 100 percent cloud cover. This in turn reduces this dataset’s file size. Approximately 20 to 30 percent of this image contains significant cloud cover.
Other image files associated with this swath includes DS1104-1043DF002_2a.tif, DS1104-1043DF002_2cb.tif and DS1104-1043DF002_2d.tif
The satellite captured this CORONA image on 10 August 1968. The image extends across an area of Wales which includes the Town of Talgarth to the east and the Town of Sennybridge to the west. The Town of Brecon, and parts of the River Usk and Brecon Beacons National Park fall within this image’s area.
This dataset was downloaded from Earth Explorer for the purpose of comparing changes to land use patterns between the years 1968 and 2011.
