File Format for Data Exchange between Graphic Data Bases

A number of interactive graphics systems have been developed for cartographic applications. These systems have different capabilities and features, and little or no general provision has been made for transferring data base content between different systems or installations. A data base interchange file format has been designed for the Computer Assisted Mapping and Records Activities System, CAMRAS, sponsored by the American Public Works Association. The Association is evaluating the format for promulgation as a standard. A description of the interchange file format is given.
