Remote Sensing Analysis of Selected Terrestrial Impact Craters and a Suspected Impact Structure in South Korea using Space Shuttle Photographs

Typical morphological elements for impact craters were detectedon all analyzed Shuttle photographs. Features with diameters smallerthan 2 km could not be successfully analyzed. The search for suitableShuttle scenes was successfully performed using on-line Internetdatabases.Image enhancement and lineament analysis were also performedon the acquired Shuttle, Landsat and SPOT images of a suspectedimpact feature in South Korea. A fault bounded polygonal rim and acentral uplift were identified on all images. A distinct system of annularand radial faults was not detected. The results of the study do notexclude the possibility of a meteoritic origin of this structure.
