Of particular interest are the applicable volume of [Sailing Directions](/source/Sailing_Directions) and the number of the [harbor chart](/source/nautical_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](/source/National_Geospatial-Intelligence_Agency). They are not random choices. The applicable [chart](/source/nautical_chart) and [Sailing Directions](/source/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](/source/National_Geospatial-Intelligence_Agency). ==Data availability== In addition to the published text edition of the World Port Index, the National Geospatial-Intelligence Agency also makes the data available in tabular and spatial formats. This includes [Microsoft Access](/source/Microsoft_Access) database and Esri [Shapefile](/source/Shapefile) formats. Archived publications are also available with past Access databases dating to 2000 and Shapefiles dating to 2010. The data is available from the National Geospatial-Intelligence Agency's World Port Index webpage.{{cite web |url=https://msi.nga.mil/Publications/WPI |title=World Port Index |publisher=National Geospatial-Intelligence Agency |access-date=October 19, 2022}} ==Sources== The text of this article originated from the preface of the ''World Port Index'' and section 413 of The [American Practical Navigator](/source/American_Practical_Navigator).
