Modeling population density by integrated analysis of Kompsat-1 images and census data

In this paper the use of panchromatic KOMPSAT-1 imagery is proposed to provide detailed information on built-up areas in suburban regions. In order to derive this information a texture analysis is utilized. In the next processing step census data are incorporated in order to perform refined demographic analysis. Assuming that the population lives in settlements rather than in agricultural areas, the census data are assigned to the actual residential areas within each census unit. Using this information a number of questions can be addressed which cannot be answered by statistical data alone.
