In order to make early and effective planning decisions on the location and design of new roads rapid methods of terrain appraisal are necessary. At an early stage in the planning of a road project the engineer needs information on factors affecting the cost of alternative routes and types of construction. The interpretation of black-and-white aerial photographs to provide information on the nature of the land surface, drainage, materials and properties of the soil cover has for many years proved to be invaluable in assisting the selection of the alignment, design and method of road construction, particularly in overseas countries. This proven technique can now be expanded by making use of the different forms of remotely-sensed data and related developments in interpretation techniques that have recently become available. The advantages of using these new surveillance techniques are discussed for highway engineering surveys in developing countries. /Author/TRRL/
