A Set of Visualization Data Needs In Urban Environmental Planning & Design for Photogrammetric Data

This paper makes a case for extending the techniques of automatic extraction of man-made objects from aerial images to include all primary elements (objects) of the urban landscape. Techniques to visualize urban landscapes for use in urban landscape planning and design are reaching a mature and productive stage of development. A lack of affordable, usable three dimensional digital data is holding back the use of these techniques in everyday practice.
