History: This file was created by merging the coast_n83 polygon file with

the islets_n83 polygon file from the State of Hawaii, Office of

Planning using the union tool in ESRI's ArcGIS 9.1. A three

nautical mile buffer was applied using the buffer tool in ArcGIS

9.1 then buffered polygons were merged. The coast_n83 and

islets_n83 polygons were clipped using the erase tool in ArcInfo

9.1. Individual polygon areas were calculated using the

calculate areas tool within ArvGIS 9.1. Projection is UTM Zone 4,

and datum is NAD 83. File was completed in December, 2006.
