Characterizing Urban Land-Cover Change in Rondônia, Brazil: 1985 to 2000
Abstract

Few studies in the Amazon have explored the evolution of urban form and composition in the region's emerging urban hierarchy. This paper presents a methodology to characterize the physical properties of urban land cover in Rondônia across multiple dates using remote sensing imagery. Three descriptive metrics are explored: (a) urban extent in terms of the area and density of impervious surfaces, (b) the relationship between urban area and urban population, and (c) trajectories of urban land-cover composition. Such datasets can contribute to longitudinal studies of urban areas and provide a first step in linking urbanization to regional land-cover change.
