K. A. Styles, E. W. Brand and A. D. Burnett write: The Working Party Report on Land Surface Evaluation for Engineering Purposes will have been read with great interest by those closely associated with work of a ‘terrain evaluation’ nature. Anyone who has been involved in the writing of a state-of-the-art document will appreciate the amount of time and effort that must have been devoted by the Members of the Working Party to their difficult task, and they are to be congratulated on producing a document which will prove to be useful to the profession. The writers must confess, however, to being disappointed that the Report fails to deal adequately with the terrain interpretation methods used in modern engineering practice. Unlike previous Geological Society working party reports, the document in question does not fully represent the current state of the art, and it therefore falls short of providing the standard source of reference that we have come to expect from the Geological Society.
The main disappointment with the Report stems from the fact that the material on which it is based is somewhat ‘dated’. As a result, it does not fulfil the objective stated in Section 1.2, namely ‘to report on Land Surface Evaluation outlining the state of the art and making recommendations for good engineering practice’. It is noted that the Working Party was set up in 1974, and perhaps the material for much of the Report was assembled soon after that time, for surely the state of the
