Description:

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).

Purpose:

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 without shorelines from 1970-1979 and 1994, which contained greater inaccuracies due to uncertain source photography, registration errors, storm events and poor contrast.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

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.

Logical_Consistency_Report:

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.

Completeness_Report:

This dataset contains the measurement locations automatically established during the generation of transects by the DSAS software application and were used to calculate long-term shoreline change rates for the region. Additional measurement locations would have been generated for the 1970s and 1994 shorelines at each transect, but these shoreline data were excluded from the rate calculations.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.

Process_Step:

Process_Description:

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) without the 1970-1979 and 1994 shorelines. 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_20121218_090819.dbf. Output intersects table name= OuterCapeCod_transects_intersect_20121218_090819.dbf.
