Mapping urban growth in Boca Raton Florida, over a thirty year period

The rapid increase of urban growth is a major issue for many regions around the world, which result in astounding loss in farmlands and increase in population densities. It important that urban growth be monitored as it will aid the local government in implementing the appropriate measures for a growing population. The city of Boca Raton, Florida, is the case study for this research. A multi-temporal analysis is done of five Landsat satellite images over a thirty year time period, 1973-2002. Textural analysis was performed on each of the images, to delineate the urban areas. Three by-products resulted from the textural analysis: time series tinted overlays, dasymetric mapping and a series of animated maps, showing the movement of growth across the landscape through time. All the resulting products of the time series analysis were used to show the magnitude and direction of growth over time.
