Data in this report are available as downloadable files based on the ten geomorphic regions that make up the New England and Mid-Atlantic study area. The index maps highlight areas of shoreline coverage in yellow and indicate the extent of each region. All vector data are delivered as ESRI shapefiles in the geographic coordinate system (WGS84) and distributed with Federal Geographic Data Committee (FGDC) compliant metadata in Extensible Markup Language (*.xml) format. Tabular data are delivered as dBase IV (*.dbf) structured files which can be read with ESRI ArcGIS software as well as many other available spreadsheet programs. Metadata are also provided for all spatial and tabular data in text (*.txt) and FGDC Classic (*.html) format. ESRI ArcCatalog 9.x can also be used to examine the metadata in a variety of additional formats.
This report includes all of the files necessary to perform shoreline change analyses using the Digital Shoreline Analysis System (DSAS) software. Please refer to Thieler and others (2009) for information about the DSAS software application that was used to perform the rate calculation methods, which are discussed at length in the full report on the National Assessment of Shoreline Change for the New England and Mid-Atlantic Coasts (Hapke and others, 2010).
The following files are available for download for each geomorphic region (see index maps):
- Compiled shorelines from multiple sources which are attributed within each dataset and included in the metadata.
- Offshore baseline used for generating shore-normal transects in DSAS
- Long-term transect file with rates
- Short-term transect file with rates
- Shoreline uncertainty table containing the lidar positional uncertainty, bias values for the MHW - HWL shoreline proxy offsets, and the uncertainty associated with each bias value.
Data layers can be downloaded individually using the table below. Individual layers are provided as WinZip files. If WinZip® is not currently installed on the local system, go to WinZip® (http://www.winzip.com) to download the latest version.
