Urbanization and barangay convexity relationship analysis

Abstract

Human population studies show an increasing population density in urban areas. In this study, we present a method for measuring the growth and spatial extent of urbanization using readily accessible remote sensing data. We obtain land use/land cover data taken by the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor of NASA. The urban tile density of barangays are compared to its convexity. The convexity of a barangay is used as a measure for the regularity of its shape, i.e. the absence of infoldings and protrusions.
