Applied geological mapping in the Wrexham area : computing techniques

The Wrexham area applied geological mapping project (Contract No. PECD/7/1/290) was commissioned in 1988 by the Department of the Environment on behalf of the Welsh Office, and carried out by the British Geological Survey. The objectives were to provide cover of modern geological maps for the Wrexham area and to present applied thematic information on geological conditions as they relate to planning and development. The main results of the study are given in Hains (1991). The present report gives an account, as required in the contract schedule, of the techniques used for the production of the computer database and the preparation therefrom of applied maps. Conclusions are recorded on the suitability of the systems for application in further applied mapping studies.
