Vector Shoreline
 |
 |
Vector shoreline in ESRI shapefile format has been created from NOAA raster charts. The shoreline has been created from map scales between 1:10,000 and 1:80,000 with emphasis on high spatial resolution. |

| The main purpose of the Vector Shoreline Project is to provide public access to recently charted coastline data. The project is targeted at map scales between 1:10,000 and 1:80,000 with emphasis on high spatial resolution. The derived Mean High Water and Mean Lower Low Water lines were originally processed from binary raster files that were concurrently used in NOAA nautical chart production, though the derived outlines may not always correspond to these well-defined shoreline datums. The derived shorelines are referenced to geographic coordinates and imported to the ESRI shapefile format that is used in many GIS applications. As derived from the raster nautical charts, the Mean High Water line and the Mean Lower Low Water line are respectively represented by files with "gd20" and "mar" in the name; for example, "1276gd20.shp" and "1276mar.shp". FGDC compliant metadata for the Vector Shoreline series is available online. |
