Abstract:
This dataset represents a compilation of vector shorelines in the Grand Bay National Estuarine Research Reserve (Mississippi and Alabama) from 1848 to 2017. Shoreline data were obtained from multiple data sources, including the U.S. Geological Survey (USGS), the National Oceanic and Atmospheric Administration (NOAA), the Grand Bay National Estuarine Research Reserve (GBNERR), and the Mississippi Office of Geology (MOG). All shoreline data types have uncertainty associated with delineating the shoreline location, particularly with vegetated coastlines. For this study, the "apparent shoreline" was mapped for all data sources. The "apparent shoreline" is defined as "where the actual shoreline is obscured by marsh, mangrove, cypress, or other type of marine vegetation, the outer edge of the vegetation is mapped” (Shalowitz, 1964). In the case of aerial imagery, vegetation-water boundary was digitized. Field-surveys identified the edge of the dominate vegetation or the eroding scarp line. Shorelines were obtained from the original provider, or digitized, and merged into a single file, in order to conduct shoreline change analyses. Datasets were compiled and analyzed using the R package Analyzing Moving Boundaries Using R (AMBUR) program. Rates of shoreline change can be used for evaluating living shoreline resources, decision-making for future resource planning, and restoration of both protected and open-ocean shorelines. This data release contains shorelines from 1848-2017 along with transects with rates of change joined to the data table. This metadata record should be reviewed in its entirety to ensure specific data is suitable for other studies as some shorelines were specifically digitized for use with transects in this study. Shorelines from 1942, 1975, 1986, 1992, 2004, 2006, 2014 have limited spatial resolution. All shorelines labeled GBNERR in the “Source” field of the attribute table, and 2016 and 2017 GPS shorelines from the USGS, are previously unpublished data sets.
Purpose:
The purpose of these data is for the calculation of shoreline change for marsh shorelines of the GBNERR from 1848 to 2017.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report: No formal attribute accuracy tests were conducted.
Logical_Consistency_Report:
Vector shoreline features and attributes were checked for completeness and accuracy.
Completeness_Report:
Dataset is considered complete for the information presented. Some dated shorelines do not have complete coverage over the entire study area (for example, 2017 shorelines were collected using a GPS system and are only available for select study areas); however, this was acceptable as the analysis method accounts for the available dates only. In addition, select shoreline dates (1848, 1942, 1975, 1986, 1992, 2004, 2006, and 2014) were created using a point intersection of shoreline and transect, and are intended for use only with the transects also published in this data release. Users are advised to read the rest of the metadata record carefully for additional details.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
A formal accuracy assessment of the horizontal positional information in the dataset has not been conducted. Elevation and water levels were not addressed in this study. For additional information on data collection techniques see the source metadata.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Several factors may influence the accuracy and uncertainty of shoreline position for vegetated shorelines, such as water level. Water level at the time of imagery collection is largely unknown for most historical imagery, therefore we cannot account for shoreline positional errors associated with water level. Published uncertainty estimates for sandy shorelines were used for all shorelines in this study, with the exception of 1993, 1995, 1999, 2001, 2010, 2012, and 2017. Shorelines in this study, with the exception of the dates above, should be regarded as less conservative than errors that may account for uncertainty in digitization of vegetated shorelines from aerial imagery. For additional information on data collection techniques see the source metadata.

Process_Description:
Shorelines for 1942, 1975, 1986, 1992, 2004, 2006, and 2014 were downloaded from various internet sources and digitized within ArcGIS 10.5.1 at locations where the transects (also available at, https://doi.org/10.5066/P9JMA8WK) and shorelines intersected. Using XTools Pro (v.17) "polylines from points" tool, vector shorelines were created. The location between each point was interpolated so the specific shoreline location between each point might not represent the actual shoreline position. To see the transect intersection locations, the ArcGIS editor toolbar can be used. Shorelines are not previously published and are available through this data release webpage (https://doi.org/10.5066/P9JMA8WK).

Process_Description:
GPS shorelines were generated by the U.S. Geological Survey using Ashtech Z-Xtreme DGPS units from various collection dates in 2017. Shorelines were collected by walking along the shoreline with a GPS receiver at roughly 1-meter intervals and taking measurements along the marsh scarp. GPS points were processed and turned into an ArcGIS shapefile. The points were converted into vector shorelines using XTools Pro (v.17) "polylines from points" tool. The location between each point was interpolated so the specific shoreline location between each point might not represent the actual shoreline position. To see the transect intersection locations, the ArcGIS editor toolbar can be used.

Process_Description:
Shorelines were compiled from all available data sources as both previously published shorelines or ones created for this study. Reguardless of the data source, shorelines were edited in ArcGIS (version 10.5) so that only the desired shorelines were included in the final dataset. For example, historical shorelines derived from T-sheets included lines for map boundaries and features not designated as shorelines. These features were deleted. Once shorelines were edited and checked, all dated shorelines were merged into a single dataset. Attributes were edited to include information regarding the date and source of the original data. Compiled shorelines were processed using the AMBUR (Analyzing Moving Boundaries Using R) statistical package for R (version 3.4.3) tool to add required missing attributes. AMBUR performs shoreline change analysis on vector digital shorelines. All necessary attribute fields must be present in order to run various AMBUR functions; the following fields are required for boundaries: "Id", "DATE_", "ACCURACY", "SHORE_LOC", "CLASS_1", "CLASS_2", "CLASS_3", and "GROUP". In order to determine if all the required fields were present in the merged boundary datasets, an AMBUR sub-routine (ambur.check) was used to check all shoreline shapefiles for missing attribute fields. For more information about the AMBUR shoreline requirements see the AMBUR user manual at http://ambur.r-forge.r-project.org/user/ambur%20basic%20user%20guide%201_0a.pdf. After the AMBUR analysis was finished, extra fields ("SHORE_LOC", "CLASS_1", "CLASS_2", "CLASS_3", and "GROUP") were removed as they were not necessary.

As stated above, several factors may influence the accuracy and uncertainty of shoreline position for vegetated shorelines, such as water level. Water level at the time of imagery collection is largely unknown for most historical imagery, therefore we cannot account for shoreline positional errors associated with water level. Published uncertainty estimates in Hapke and other (2011) are for sandy shorelines, but were used for (1942, 1975, 1986, 1992, 2004, 2006, and 2014). These values should be regarded as less conservative than errors that may account for uncertainty in digitization of vegetated shorelines from aerial imagery. The 2017 USGS GPS shoreline accuracy was calculated based on the average positional error of the GPS points for each line segment. The MOG and GBNERR GPS data was assigned a 5 meter uncertainty value based on reported values in the MOG source metadata. The 2010 and 2012 uncertainty values were computed as the square root of the sum of squares of the image resolution, image uncertainty, and the maximum digitization error of 1 meter. For additional information see the source metadata.
