The original data set was created as follows:
This dataset was generated using a variety of sources. The raster nautical charts were first reprojected from their original projection/datum to UTM Zone 4, NAD 83 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. Data points were then plotted using the individual nautical charts as base maps. The data was then merged into a single dataset/shapefile which covers the entire state. Completed December, 2002.
