"This points shapefile represents the location of the cruise ports in Jamaica and intensity of visitation. This dataset was created on 24th April 2003 and represents all cruise ports in the Wider Caribbean and the number of calls by cruise ships that are scheduled between 1st May 2003 and 1st May 2004. Cruise ships alter their ports of call from year to year and there are other destinations that have not been included in this dataset, as no ships are scheduled. The base dataset for port locations was the NIMA, World Port Index-Publication 150, 2002. Other locations were georefernced at WRI by digitized onscreen using World Vector Shoreline as the reference.
