NATIONAL SHORELINE
MANAGEMENT STUDY
 Multi-Year Study – interagency effort to determine:
 • Extent and cause of shoreline erosion and accretion of
   U.S. shoreline
 • Assess the economic and environmental impacts of
   these shoreline changes
 • Examine Federal, State and Local Agency roles and
   resources in shoreline management
    Goals:
   • Identify shoreline areas that have “Critical Erosion”
   • Recommend levels of Federal, State and Local participation
      in shore protection
   • Use of systems approach to sand management

Partners: NOAA, USGS, FEMA, MMS, NPS, FWS, Coastal States Org….
Develop National-Scale Inventory of shoreline change data


     Many Federal Agencies and Coastal States
     have compiled measurements of
     erosion and accretion and
     shoreline change patterns

   Shoreline change inventory on national scale will
      provide support to NSMS Work Groups:
      • Shore Processes
      • Environmental Processes
      • Economic Processes
      • Agency Roles & Contributions
      • Systematic Sand Management

                      These data were created by the National Ocean Service,
                      National Geodetic Survey (previously the National Ocean
                      Survey) as part of its ongoing mission to map the coastline
                      of the United States. The NOAA National Ocean Service,
                      Coastal Services Center developed the procedures used in
                      this project and was responsible for project oversight. The
                      project intent was to rescue valuable historical data and
                      make it accessible and useful to digital mapping products.
                      This file is a further conversion of that product from a
                      raster to a vector product that may be useful for
                      Electronic Charting and Display Information Systems (ECDIS)
                      and geographic information systems (GIS).

                    These data were automated to provide a suitable geographic
                    information system (GIS) data layer depicting the
                    historical shoreline for Alabama. These data are
                    derived from shoreline maps that were produced by the NOAA
                    National Ocean Service including its predecessor agencies………………

          Mapping Application

• An online mapping application using
  ArcIMS has been created to distribute
  and display digital data collected for the
  efforts of the NSMS program.
• Application is built upon existing industry
  standard technology and supports
  USACE Spatial Data Standards.
  ArcIMS provides the engine for
  distributing the online maps.
Dynamic mapping interface doesn’t require any special software.
Only a web browser is needed to allow users have to build a
map based on their preferences.

Data layers can be toggled, and users can zoom, pan, measure,
query, identify, label, and print the desire information.
The shoreline layers in the map service, allow the user to view
specific details on selected line segments. Here the user can see
the type, scale, and date of the shoreline line segment.
     Summary

• The online mapping application allows
  all users, regardless of skill level, to
  access digital data in a user friendly
  format.
• General user can use interface to
  browse the datasets and advanced
  users can download the data directly
  from the web site and migrate or link
  to an existing enterprise GIS.
