Abstract
Updated U.S. Geological Survey digital line graph (DLG) data collected at a scale of 1:2,000,000 are now available on two compact discs-read only memory (CD-ROM). Each CD-ROM contains digital cartographic data for 49 States and the District of Columbia. The U.S. Virgin Islands, Puerto Rico, and Alaska will be ready within the next year.
These DLG data were originally collected from maps published in 1970. Extensive revisions have been made and no data source more than 5 years old was used in this update.
In addition, text files containing information such as place names and population have been added for the first time. The records in these text files can be related to corresponding features in the DLG data files.
Metadata that comply with the Federal Geographic Data Committee Content Standards for Digital Geospatial Metadata are included for each category of DLG data.
