The technique of terrain evaluation which is described in this report is a method of assessing the potentials and limitations of any area of ground for a specified land use by means of a conscious and organised acquistion of data about the terrain. The note is concerned mainly with data useful to the highway engineer, and the methods employed to obtain these data - land system mapping, soil properties relevant to a particular land use, are described. Information is provided whereby such techniques can be used to plan transport development. An explanation is given of:- (1) the principles of terrain evaluation, (2) the methods used, including the interpretation of remote sensing such as aerial and satellite photography, and (3) the applications of terrain evaluation, with 'real life' examples drawn from the work of the overseas unit.(a)
