Managing our urban future: the role of remote sensing and geographic information systems

Urban growth is inevitable over the next two decades. The bulk of this growth will take place in less developed countries. This presents a formidable challenge for urban planners and managers. With this in mind, this paper considers some of the ways urban planners can make use of recent developments in remote sensing and geographic information systems technology to respond to this challenge. The discussion is divided into four sections. The first of these considers the nature of the tasks involved. The second examines the potential of remote sensing and geographic information systems to assist in these tasks in general terms. The third section presents some of the findings of three case studies of contrasting application areas in the urban planning field which give some insights as to how these tools can be used to respond to this challenge. The final section rounds off the discussion with a vision of sustainable urban development and its implementation at the local level.
