NOAA's Shoreline Data Explorer

The National Oceanic and Atmospheric Administration's (NOAA) Shoreline Data Explorer web site provides user's access to both current and historical high-resolution digital shoreline of the United States and it's possession's. NOAA's Shoreline Data Explorer allows users to:

· View available vector shoreline project boundaries
· View vector shoreline data
· View and download FGDC compliant metadata
· Make printable maps
· Download vector shoreline shapefiles

The development of the shoreline data explorer represents a new turning point in web based technology for the National Geodetic Survey. NOAA's Shoreline Data Explorer uses ESRI's ArcIMS (Internet Map Service) software to view and disseminate vector shoreline data. With the help of NOAA's Coastal Services Center NGS was able to bring into the data base much of the historical shoreline data, digitized in a vector format from the preexisting topographic surveys. The web based program also shows all of NGS' contemporary digital photogrammetric shoreline. The shoreline data explorer will provide the user with a greater opportunity to access vector shoreline data that before was not readily available. While, at this time, this information is not intended for navigational use, it will be very beneficial to GIS users who are looking for up to date shoreline information.
