Abstract:

The present paper, demonstrates a methodology for constructing a dynamic model of Land useLand cover from sequential aerial photographs, over a period of 1938-1976, in the south eastern region of the state of Ohio, USA. The USGS Land useLand cover legend was adapted to identify the classes, starting from the one suffering highly rejection mechanism Water to that of climax Mixed mesophytic forest. A discretization procedure was applied to divide the site into 56 equal size cells 1 km by 1 km. Photogrammetry techniques were applied to transfer the ground coordinates of the cell corners nodesinto photo coordinates. The central projective equations were the main tools in this transformation. Photo coordinates were plotted on the most recent aerial photographs 1976. Zoom transfer-scope was used in transformation of these coordinates to the 1938, 1951, 1958, 1966 and 1976 aerial photographs. Land useLand cover classes were mapped for each cell for each set of photographs. Acreage was computed at a one hectare resolution. Cluster analysis was used to group cells of similar Land useLand cover composition of the 1976 aerial photographs. Cells each cluster were tracted through time to determine the pathway through which they passed and to determine theri initial stage in 1938. A proposed Land useLand cover model was constructed indicating the pathways and the most responsible mechanisms.
