Road Route Selection Using (GIS) and Remote sensing techniques Mohammed Khair Mohammed Ali Director General Sudan National Survey Authority, Sudan Email: Khair20y@yahoo.com Eng. Ammar Babikir Mahmoud Amina Ahmed Abdel Rahman Sudan is one of the biggest countries in Africa and still under devolvement. Roads are one of the most important factors in development. Road route selection is an important stage in road construction. Many factors govern road route selection including; type of subgrade, topography, availability and cost of materials, environmental impacts, social and economical services …etc. Using (GIS) and remote sensing techniques in road route selection will reduce cost and time. The aim of this paper is to select the best road route between Karima and Dongola towns in north Sudan. This road will serve Marawi Dam area. Approximate road lengt! h is 180 Km. running North West.
