PROCESSING AND SYNTHESIS OF IMAGES FROM GEOMETRIC DATA

TRAITEMENTS ET SYNTHESE D'IMAGES A PARTIR DE DONNEES GEOMATIQUES

In this two-part study, the authors develop descriptive tools for extracting the highway system from a vector-type planimetric data base. To that end, they study the data recovery, graphic semiology, and data structure that derive from it. They then analyze and correct the data in order to extract the topology and geometry from information on the highway system contained in an urban data bank (St. Etienne). They present two extraction methods. The second part of the study deals with visualization of urban space through computation of synthesis images. It includes: an in-depth study of the PS390 graphics system of Evans & Sutherland, its functioning and very specific programming language; and an analysis of the authors' research, which enables interactive production of animated films from urban space (TRAPU) data bank.
