Introduction

This reference report provides information about electronic records containing digital cartographic data open to the public in the custody of the National Archives. The data files contain some or all vector format data, wherein linear features are identified by directional pairs of x,y coordinates. The data is suitable for use in Geographic Information Systems for purposes of displaying and allowing for analysis of spatial attributes and characteristics.

Many electronic records series, not listed here, include data elements that are geographic in nature. Such files may also be used as input to Geographic Information Systems. They include files that identify latitude and longitude, Universal Transverse Mercator (UTMs), census tracts, cities/towns, counties, states, or ZIP codes, etc.

Researchers may order copies of the computerized data files on removable media for a cost-recovery fee and analyze the records directly, using whatever hardware and software they have. For more information on ordering data files, see: Ordering Information for Electronic Records. Descriptions of the series and data files listed in this report are in NARA's Online Catalog. The online catalog can be searched by title, National Archives Identifier, type of archival material, or keyword.

Each records in the files identifies a segment of a feature on a map by its node points (intersections or terminations of selected map features), address ranges, and associated geographic codes. These files were digitized by determining x,y coordinate values for each node point. Some of the computer files used in preparing the GBF/DIME Files are also available as part of the series Geographic Reference Files and Related Computer Programs Files from the 20th Census of Population and Housing.
