Use of Image Registration Technique in Brasilia's Urban Growth Monitoring

摘要

This paper describes the use of an Image Registration Program in the studies of the urban growth. This program implemented in the Image-100 (Multispectral Images Analyzer) permits a quick identification of growing areas by means of the overlap of the same scene in two or three different dates, and the use of adequate filters. The city of Brasilia, Brazil, was selected for test area. The dynamics of Brasilia urban growth was analyzed with overlap of scenes dated June 1973, 1978 and 1983. The results show the utilization of the Image Registration Technique for the monitoring of the urban growth.
