The feasibility of the storage of geotechnical records in a computerised databank is discussed. Both the use of a large mainframe installation and an inexpensive micro-processor have been investigated. The object has been to develop a system in which geological information in the form of borehole records, etc., may be stored efficiently and in such a manner that on retrieval the information may be presented to the Engineer or Geologist in a form of immediate relevance to his needs. A pilot study based on borehole records from the Thames Estuary has produced encouraging results.
