Layer Name:       Aids To Navigation

Shapefile Name:   AidsToNavigation	

Layer Type:       Point

Status:           Complete

Geog. Extent:     Main Hawaiian Islands

Projection:       Universal Trans Mercator, Zone 4 (Meters)

Datum:            NAD 83

Description:      This dataset contains those aids to navigation located in
                  marine waters within the vicinity of the main Hawaiian Islands
                  and recorded on the nautical charts.
		
Source:           NOAA Raster Nautical Charts		

History:  The raster nautical charts were first reprojected from
          their original projection/datum to UTM Zone 4, Old Hawaiian
          using NOAA's Nautical Chart Reprojector v1.8.3. NOAA's
          ArcView ChartViewer extension was used to display the
          reprojected nautical charts in ArcView v3.2. Subject areas
          were then digitized off the individual nautical charts and
          merged into a single dataset/shapefile which covers the
          entire state. The dataset was then transformed to UTM Zone
          4, NAD 83, to adhere to new project requirements, using the
          Hawaii Datums and Projections extension in ArcView.  Completed
          December, 2002.
