SUMMARY Today, nearly half of the world's population lives in cities. In developing countries, people are deserting rural areas while population is rising rapidly. In less than 20 years from now, these two factors will combine to drive over two billion people into urban areas, which in some cases are already overcrowded. The conditions that many new city dwellers find on arrival simply compound the situation. Most urban growth falls outside formal planning controls, thus increasing economic and social pressures and exacerbating health and hygiene problems. The main advantages of Remote Sensing with GIS are to bring parties together, to spread and improve idea, to support the decision-making process, and to evaluate projects.
