Title:
Digital Shoreline Analysis System version 4.3 shoreline intersection points used to calculate long-term shoreline change statistics for the Outer Cape Cod coastal region from Long Point in Provincetown to Monomoy Island (OuterCapeCod_intersects_LTw.shp)
Abstract:
Due to continued coastal population growth and increased threats of erosion, current data on trends and rates of shoreline movement are required to inform shoreline and floodplain management. The Massachusetts Office of Coastal Zone Management launched the Shoreline Change Project in 1989 to identify erosion-prone areas of the coast. In 2001, a 1994 shoreline was added to calculate both long- and short-term shoreline change rates at 40-meter intervals along ocean-facing sections of the Massachusetts coast.
The Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) in cooperation with the Massachusetts Office of Coastal Zone Management, has compiled reliable historical shoreline data along open-facing sections of the Massachusetts coast under the Massachusetts Shoreline Change Mapping and Analysis Project 2013 Update. Two oceanfront shorelines for Massachusetts (approximately 1,800 km in total length) were (1) delineated using 2008/09 color aerial orthoimagery, and (2) extracted from topographic LIDAR datasets (2007) obtained from NOAA's Ocean Service, Coastal Services Center. The new shorelines were integrated with existing Massachusetts Office of Coastal Zone Management and USGS historical shoreline data in order to compute long- and short-term rates using the latest version of the Digital Shoreline Analysis System (DSAS).

    ShorelineI
    Date of shoreline position; date of survey as indicated on source material in the format mm/dd/yyyy. A default date of 07/01 was assigned to shorelines where only the year was known (month and day unknown). Using July, the mid-point month of the calendar year, minimizes the potential offset to the actual shoreline date by a maximum of six months. (Source: U.S. Geological Survey)

    The along-transect distance from the baseline to the shoreline point measured in meters (State Plane Masachusetts Mainland FIPS 2001, NAD 83). Positive values are used when the reference baseline is landward (onshore) of the shorelines. Negative values are used when the reference baseline is seaward (offshore) of the shorelines. The positive/negative values provide appropriate directionality for describing erosional or accretional trends in shoreline movement. (Source: U.S. Geological Survey)

    Due to the highly dynamic barrier system around Monomoy, MA, and the complexity of the associated vector shorelines in this area, it was necessary to calculate shoreline change statistics for the Outer Cape Cod region in batches, separating the backshore shorelines (sheltered coast) from Atlantic-facing (open ocean) shorelines. This attribute identifies which calculation run the data corresponds to. (Source: U.S. Geological Survey)

Why was the data set created?

This dataset contains the measurement locations used by the Digital Shoreline Analysis System (DSAS) software to compute long-term rate of change statistics for the Outer Cape Cod region of Massachusetts. The points represent the individual shoreline locations along each measurement transect generated by DSAS. The data can be used to identify the number of shorelines used to compute rates at a given location as well as the specific shoreline dates. Long-term linear regression statistics were calculated with all of the historical shorelines compiled for the Massachusetts Office of Coastal Zone Management Shoreline Change Project.

    The southern end of the Outer Cape Cod region from Nauset Beach in Chatham to Monomoy Island is a highly dynamic barrier system. Because of the complexity of the associated vector shorelines in this area, it was necessary to calculate shoreline change statistics for the Chatham-Monomoy section in batches, separating the backshore shorelines (sheltered coast) from Atlantic-facing (open ocean) shorelines. Therefore, shoreline change statistics were calculated three times to compute a complete set of rates for the Outer Cape Cod region. The attribute field Calc_run represents the extent of each section used to calculate rates for the Outer Cape Cod region, where:
    1- Includes the ocean-facing coast from Long Point in Provincetown to Nauset Beach in Orleans, including the backshore (sheltered) region within Pleasant Bay; 2- Includes the Atlantic ocean-facing coast (open ocean), southeast of Toms Neck in Chatham to Monomoy Island. 3- Includes the backshore (sheltered) coast, southeast of Toms Neck in Chatham to Monomoy Island;
    Rate Calculations Performed using DSAS v.4.3 for ArcMap 10 for the Outer Cape Cod region section 1 (ocean-facing coast from Long Point in Provincetown to Nauset Beach in Orleans, including the backshore (sheltered) region within Pleasant Bay). Parameters Used: shoreline layer=OuterCapeCod_shorelines, shoreline date field=Date_, shoreline uncertainty field name=Uncy (additional shoreline data stored in OuterCapeCod_shorelines_uncertainty.dbf), the default accuracy=10.8 meters, shoreline intersection parameters=nearest, stats calculations=[Shoreline Change Envelope (SCE), Net Shoreline Movement (NSM), Linear Regression Rate (LRR)], shoreline threshold=3, confidence interval=90%, Output rate table name=OuterCapeCod_transects_rates_20121212_095458.dbf.

    Date: 12-Dec-2012 (process 5 of 19)
    Due to the lack of continuous long-term shoreline position data, some transects intersected shorelines from 1970-2009, but did not intersect shorelines prior to 1970, which resulted in long-term linear regression rates that were identical to the short-term. Transects and corresponding intersects used to compute long-term linear regression rates that did not intersect long-term shoreline data (1844-1970) were deleted in a standard editing session (ArcMAP v10).

    Edits to the metadata were made to fix any errors that MP v 2.9.36 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Attempted to modify http to https where appropriate. Added a landing page link as the first link in the identification section. Fixed online link to DSAS cross-reference. The distribution format name was modified in an attempt to be more consistent with other metadata files of the same data format. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file.

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    The attributes of this dataset are based on the field requirements of the Digital Shoreline Analysis System and were automatically generated by the software during the calculation of shoreline change rates performed by the software.
  2. How accurate are the geographic locations?
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    This dataset contains the measurement locations automatically established during the calculation of rates by the DSAS software application and were used to calculate long-term shoreline change rates for the region. Additional transects (and resulting measurement locations) may have been generated but did not intersect the minimum requirement of three shorelines to calculate long-term rates. These data are part of a state-wide assessment of shoreline change that includes over 26,500 individual transect locations that were used to compute both short- and long-term rates of change, based on almost 9200 linear kilometers of historical shoreline position data. It is very likely that some gross errors or blunders were introduced during compilation and analysis of this large amount of information. Such errors have been described in the context of shoreline change mapping as coarse errors (Fenster and others, 2001) and can generally be considered to affect only a very small percentage of the overall dataset.
    Fenster, M.S., Dolan, R., and Morton, R.A., 2001, Coastal storms and shoreline change: signal or noise?: Journal of Coastal Research, v. 17, no. 3, p. 714-720.
  5. How consistent are the relationships among the observations, including topology?
    These data were generated using DSAS v.4.3, an automated software program which does not perform checks for fidelity of the input features. The measurement locations represented by this point file are generated during the rate calculation process, after editing of the transects is complete.
