The original file was downloaded by county from www.geographynetwork.com in May, 2001. Data from the 5 counties were merged into one layer using ArcView's Geoprocessing extension. It was then projected from decimal degrees to UTM Zone 4 NAD83 using 'Hawaii Datums and Projections' extension in ArcView. The coastline was clipped using the 1983 USGS DLG coastline. The Northwestern Hawaiian Islands were removed. Tract Name and Population were added from DBEDT's population table.
