The paper describes the principles of a program for terrain evaluation for engineering purposes. Terrain parameters are evaluated at various levels and the information is presented in coded form. These levels give the program its name PUCE (Pattern-Unit-Component- Evaluation). The paper sets out the procedure and the frame-work for deriving the coded description. Each level is described by a different set of parameters. Reference is made to a list of terms which encompass the whole range of variation of a particular parameter. Each term is assigned a code number. The term in the list which best describes the actual terrain is chosen and the digits corresponding to that term are taken into the description. The digits are assembled in a set order, in such a way that a digital expression of the terrain, level by level, is built up. The paper outlines storage and retrieval systems being developed to handle digitized terrain descriptions. /TRRL/
