  2. 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….

  3. 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

Metadata Identification_Information: Citation: Citation_Information: Originator: United States Department of Commerce, National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), National Geodetic Survey (NGS) Publication_Date: 20000808 Title: Vectorized Shoreline of Alabama Derived from NOAA-NOS Coastal Survey Maps Developed from 1983 - 1988 Source Data Edition: First Geospatial_Data_Presentation_Form: Map Publication_Information: Publication_Place: Charleston, SC Publisher: NOAA Coastal Services Center Other_Citation_Details: 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). Online_Linkage: http:/www.csc.noaa.gov/products/shorelines Description: Abstract: 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……………… FGDC format Federal Geographic Data Committee

  19. 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.

  20. 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.

  21. 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.

  22. 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. • http://gis.sam.usace.army.mil/ maproom/_C025/Default.asp
