Using Remote Sensing and GIS Techniques for Quick Estimation of the Population Growth in Khartoum State

Abstract

Satellite imagery acquired by IKONOS imaging system in 2003 and the analog map of the study area at scale 1:25000 (1984) have been used to estimate the population growth taken place in Halfaya Town. Remote sensing, digital image processing and GIS techniques were used to achieve the objectives of this study. Different procedures such as, image restoration, image enhancement, topology, spatial analysis and overlay have been applied to model the urban growth in the study area between the year 1984 and the year 2003 .Based on the developed GIS model of the study area the estimated population growth rate was found to be 233%. The study proved that integrated remote sensing and GIS techniques have great impact on detecting environmental changes and man-made features variations through time.
