Remote sensing application in urban fringe study a case studý — Delhi

Abstract

This paper is based on a case study of Delhi. The attempt has been made to find out the usefulness of aerial remote sensing in the study of urban fringe where all sorts of haphazard developments take place. Unauthorised construction, illegal sub-division of land, urban sprawl, environmental degradation are all parts of urban fringe Attempt has been made to find out the efficacy of aerial photos at pre-planning stage and their role in assigning various landuses for planned development of urban fringe zone. For the first time, the concept of “Urban Index” has been used to determine the scale of urbanity by aerial remote sensing technique. Growth of settlements, land speculation, impact of anticipated development proposal have been studied. Aerial photographs have been used to detect depressions, drainage pattern, flooding problems, location of high ground water table areas which are very important for a comprehensive planning and for environmental protection. Limitations of topomaps compared to aerial photographs have been worked out. The study is based on air photo-interpretation technique supported by field checking. *** DIRECT SUPPORT *** A04KF011 00003
