United States Government Memorandum: Radio Procedures

These suggestions are largely a result of two closely allied factors: first, a tape recording--either direct or one made via radio--should enable· a field geologist to record many more observations per unit time than can be made in a notebook. The observations should be to the point, but there is no reason for them to be cryptic and so potentially ambiguous to another person. Second, persons in a data facility usually have to form a mental image of the scene being described by the field man in order to understand and to plot the data. The field man therefore has to describe objects by some logical systematic procedure.
