Human needs transform the land to different activities and the quantifiable information of these dominating activities are necessary to develop future planning. In this paper three techniques, geometrical shapes and growth concept, causal modelling concept, and category rate concept are developed which are used to assess built-up areas for 2001. The shapes of built-up areas for 13 places in a Tuni region of Andhrapradesh has been estimated by imagery and incorporated in order to estimate future built-up areas by the rating method. The variables which are caused by land growth are identified and used in causal modelling to estimate future built-up areas. The areas and rates of influencing variables were used as input in the Cross Classification method.
