Abstract
Aerial photographs are applied to the study of surface geology in Niigata city and its vicinity. The area is divided into 10 surface units by photographic tone, land use, etc. The informations sinterpreted from photographs are compared with the boring data and the results of geophysical explorations. As the result, the author found the followings : 1) Geographic patterns interpreted from photographs are well correspond to subsurface geological conditions. 2) Underground conditions deeper than 5m from the surface are not represented on the photographs. Features appared on phorographs are the key that confirm geologic coditions.
