The World Port Index (PUB 150) contains a tabular listing of thousands of ports throughout the world, describing their location, characteristics, known facilities, and available services. Of particular interest are the applicable volume of Sailing Directions and the number of the harbor chart. The table is arranged geographically, with an alphabetical index.
The selection of these places is based on criteria established by the National Geospatial-Intelligence Agency. They are not random choices. The applicable chart and Sailing Directions is given for each place listed.
In order to present such a large amount of diversified data in a single volume of convenient size, a simple code is used to indicate certain types of information. The code symbols are explained at the top of each page of text.
This book is corrected by the National Geospatial-Intelligence Agency.
