ABSTRACT
The purpose of this data is to provide the United States Coast Guard with a single map layer covering all nine delineated districts contained in the Code of Federal Regulation documentation. The description of the districts is established by the Commandant under the authority delegated by CFR Title 33, Chapter 1, Part 3. This layer is a polygonal dataset that represents land and maritime boundaries for each representative United States Coast Guard district, which includes district 1, 5, 7, 8, 9, 11, 13, 14 and 17.
