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:

Rates of long-term and short-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 shoreline-change rates for the Massachusetts Office of Coastal Zone Management Shoreline Change Project.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

The attributes for these baseline data are based on the requirements of the Digital Shoreline Analysis System (DSAS) software and have gone through a series of quality assurance procedures.

Logical_Consistency_Report:

The baseline segments here were used to generate transects for shoreline change rate calculations using the Digital Shoreline Analysis System software. They do not overlap and are not necessarily continuous.

Completeness_Report:

This baseline file is complete and contains all segments used to calculate shoreline change rates along sections of the Massachusetts Martha's Vineyard coastal region where shoreline position data were available.

Lineage:

Process_Step:

Process_Description:

A baseline shapefile was constructed offshore from the time series of shoreline positions using standard editing tools in ArcMap v.9.3. The baseline was positioned to conform to changes in the combined orientation of the shorelines alongshore. This was done so that the transects generated by the Digital Shoreline Analysis System software from the baseline, would intersect perpendicular to the general trend of the shorelines.

This process step and all subsequent process steps were performed by the same person - Theresa Smith.

Process_Step:

Process_Description:

The Digital Shoreline Analysis System software requires that all features reside within a geodatabase. The baseline file was imported into a personal geodatabase in ArcCatalog v9.3 by right-clicking on the geodatabase > Import feature class. 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_Date: 2011

Process_Step:

Process_Description:

After transects were generated, it was necessary to edit sections of the baseline using the dynamic topology in DSAS that allows edits to the baseline to update the position of transects.
