An Undersea Features Names File for the Personal Computer

An undersea features names file has been created by NOAA for use in mapping the Exclusive Economic Zone (EEZ) and other ocean areas. It supplements and updates the 1981 edition of the "Gazetteer of Undersea Features", which is published about every ten years by the Defense Mapping Agency in cooperation with the U. S. Board on Geographic Names. The new data base contains 3,407 official and 2,659 additional variant names, making a total of 6066 records covering all offshore ocean areas of the world. The records are maintained in dBase III files having fields for name, type of feature, latitude, longitude, and a six digit index number to allow rapid sorting into one degree square blocks. The over 504,000- byte world data base may be sorted into smaller geographical areas, and may be further sorted on any combination of fields, using an IBM-compatible personal computer and standard dBase III commands.
