A programme for Terrain Evaluation for Engineering purposes -PUCE (Pattern-Unit-Component-Evaluation) - is described which is capable of working at both regional and local level, of acquiring information required for any design criteria and of storing all information for retrieval for future use. The programme is implemented firstly by classification of the relevant terrian followed by evaluation for the required purpose of each member of each known class recognized; lastly all information obtained during the classification and evaluation stages may be processed and stored for future use. The basis of the terrain classification system is that any area of land can be defined in terms of its topography. The system operates at 4 levels of generalization, viz. terrian component, terrain unit, terrain pattern and province. The terrain component can be defined uniquely. The terrain unit is defined as the limited association of terrain components, that form recognizable, distinctive physiographic features and the terrain pattern can be defined as the limited association of terrain units that form recognizable, distinctive landscapes. The province can be defined as the limited association of terrain patterns that are underlain by a constant suite of rocks of a defined kind. In this hierarchical system, each member of each class is composed of a limited number of repetitive members of the preceding class in a constant form of association. The evaluation stage and the information collating, storage and retrieval system are outlined.
