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) 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 consists of long-term (100+ years) linear regression shoreline change rates for the Cape Cod Bay region of Massachusetts. Rates of long-term shoreline change were computed within a GIS using the Digital Shoreline Analysis System (DSAS) version 4.3, an ArcGIS extension developed by the U.S. Geological Survey. The baseline is used as a reference line for the transects cast by the DSAS software. The transects intersect each shoreline at the measurement points, which are then used to calculate a linear regression rate for the Massachusetts Office of Coastal Zone Management Shoreline Change Project. 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.

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 generation of the transect layer or during the calculation of shoreline change rates performed by the software.
Logical_Consistency_Report:
These transect data were generated using DSAS v.4.2 and the rates were calculated using DSAS v.4.3, an automated software program which does not perform checks for fidelity of the input features. The transects were visually inspected and sometimes manually adjusted within a standard ArcMap edit session to adjust the position at which an individual transect intersected the shorelines.
Completeness_Report:
This dataset contains the transects automatically generated by the DSAS software application that were used to calculate long-term shoreline change rates for the region. Additional transects may have been generated but did not intersect the minimum requirement of three shorelines to calculate linear regression 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.

Process_Step:
Process_Description:
After transects were generated, it was sometimes necessary to modify their length using standard editing tools in ArcMap v9.3 so that they intersected the shoreline data needed for analysis. In some cases sections of the baseline were modified using the dynamic topology in DSAS that allows edits to the baseline in a standard ArcMap (v9.3) editing session to update the position of transects if the transect field is enabled as the target layer in the DSAS (v4.2) toolbar.
Process_Date: 20110915
Process_Step:
Process_Description:
After transects were generated, the entire geodatabase was upgraded to v.10 by right-clicking on the geodatabase and choosing Properties from the pop-up window in ArcCatalog v.10. The Upgrade Geodatabase button was clicked at the bottom of the General tab in the Database Properties window.

Process_Step:
Process_Description:
The shoreline rates output table (CapeCodBay_transects_rates_20121011_172308.dbf) was joined to the transect feature class in ArcMap v.10 by right-clicking on the transect layer > joins and relates > join > join attributes from a table. Parameters: join field - ObjectID; table to join - CapeCodBay_transects_rates_20121011_172308; field in table: TransectID; join options - keep only matching records.
Process_Date: 20121011
Process_Step:
Process_Description:
The joined data were exported to a shapefile in ArcMap v.10 by right-clicking the transect file, choosing data > export data. The new shapefile was named CapeCodBay_transects_rates_LTw.shp and permanently adds the joined rate fields to the transect attribute table.
Process_Date: 20121011
Process_Step:
Process_Description:
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 short-term linear regression rates. A filter was applied to the transect/rates data in ArcMap v10: 1) Select by Attributes > create new selection: SELECT FROM MA_shorelines.shp WHERE [Year] >=1970; and 2) Select by Location, Target layer: CapeCodBay_transects_rates_LTw.shp, Source layer: MA_shorelines.shp, parameters: use selected features spatial selection method: Target layer(s) features intersect the source layer feature). Transects that did not intersect long-term shoreline data (1844-1960) were deleted in a standard editing session (ArcMAP v10).

Attribute_Label: LRR
Attribute_Definition:
Linear Regression Rate- A linear regression rate-of-change statistic was calculated by fitting a least-squares regression line to all shoreline points for a particular transect. The best-fit regression line is placed so that the sum of the squared residuals (determined by squaring the offset distance of each data point from the regression line and adding the squared residuals together) is minimized. The linear regression rate is the slope of the best-fit line. The rate is reported in meters per year with positive values indicating accretion and negative values indicating erosion.

Range_Domain:
Range_Domain_Minimum: -4.2

Attribute:
Attribute_Label: LR2
Attribute_Definition:
R-squared statistic, or coefficient of determination of linear regression, is the variance in the data calculated by DSAS that is explained by a regression. It is a dimensionless statistic that ranges from 1.0 to 0.0 and measure how successfully the best-fit line accounts for variation in the data. R-squared values close to 1.0 imply that the best-fit line explains most of the variation in the dependent variable. R-squared values close to 0.0 implies that the best-fit line explains little of the variation in the dependent variable and may not be a useful model.

Attribute:
Attribute_Label: LSE
Attribute_Definition:
The predicted (or estimated) values of y (the distance from baseline in meters) are computed for each shoreline point by using the values of x (the shoreline date) and solving the equation for the best-fit regression line (y=mx+b). The standard error is also called the standard deviation.

Attribute_Domain_Values:
Range_Domain:
Range_Domain_Minimum: 0.02
Range_Domain_Maximum: 164.76
Attribute:
Attribute_Label: LCI90
Attribute_Definition:
The standard error of the slope with confidence interval describes the uncertainty of the reported rate. The LRR rates are determined by a best-fit regression line for the shoreline data at each transect. The slope of this line is the reported rate of change (in meters/year). The confidence interval (LCI) is calculated by multiplying the standard error (also called the standard deviation) of the slope by the two-tailed test statistic at the user-specified 90 percent confidence. This value is often reported in conjunction with the slope to describe the confidence of the reported rate. For example: LRR = 1.2 LCI90 = 0.7 could be reported as a rate of 1.2 (+/-) 0.7 meters/year.
