Holdings, Storage and Retrieval of DOD Gravity Library Data
Abstract
The Department of Defense (DOD) Gravity Library, maintained by the Defense Mapping Agency Aerospace Center, has grown from a small card storage file to a massive data file contained on magnetic tapes. In the growth process, the library has progressed from the use of a various assortment of card processing equipment to the use of a UNIVAC 1108 computer system. The tremendous increase in holdings and requirements necessitated the establishing of standard formats for all gravity and related data. The receipt of data in various forms and the reduction of this data to a common form made it necessary to develop improved processing techniques for inputting new data. Voluminous retrieval and maintenance of automated data required improved techniques when addressing inquiries to such large files. This report is intended to explain the holdings, system of storage, maintenance of files and retrieval of data. The receipt of data in various forms and the reduction of this data to a common form made it necessary to develop improved processing techniques for inputting new data. Voluminous retrieval and maintenance of automated data required improved techniques when addressing inquiries to such large files. This report is intended to explain the holdings, system of storage, maintenance of files and retrieval of data. Included also is a brief description of a variety of our processing techniques and an indication of how these techniques are related to each other in the description of the computer programs most frequently used in accomplishing our assigned mission.
