The report describes a system for organizing a set of topics and related literature references in a selected field of the earth sciences. The concept of a drainage basin was selected to illustrate a conceptually-distinct field of research of interest to geologists and physical geographers. Problems associated with coding and integration of the relevant literature are pointed out. The concept of a drainage basin, initially selected as a fairly self-contained subject, was found to be more complex than originally realized. To keep the report within reasonable bounds, the subject was subdivided into several major topics, which include first the geometry of the basin considered as a physical object definable as a natural subdivision of the earth's land surface. This is followed by various attributes associated with the basin, such as soils and bedrock, streams and subsurface water in the basin, and climatic features. The system used includes three types of punched cards. The first relates to the topics discussed, the second ties in the relevant literature, and the third provides comments and specific references to individual items. Machine print-outs provide tabulated examples of the system, and a condensed bibliography of drainage-basin literature is given. (Author).

A survey of the state-of-the-art in the evaluation of natural terrain by earth-science techniques and measurement systems is presented in response to a need that existed for many years. This report considers the terrain as an envelope of the environment and all related parameters that are basic in an evaluation for relevant military applications such as unimproved landing areas, trafficability, site selection for operational facilities, terrain reconnaissance and surveillance, and target detection within a masked terrain complex. Methods of terrain-data acquisition, analysis, and evaluation and their limitations are reviewed. The status of research and development, specifying the gaps in technology, is summarized with accompanying conclusions. The report forecasts the requirement for an automated terrain-data acquisition, storage, and display system. Information pertaining to the classification of terrain data, field devices to measure bearing strength, and a visualized optimum remote sensing system is also given in the appendix. A glossary and a comprehensive bibliography are included. (Author).
