Description:

Abstract:

Shoreline change analysis is an important environmental monitoring tool for evaluating coastal exposure to erosion hazards, particularly for vulnerable habitats such as coastal wetlands where habitat loss is problematic world-wide. The increasing availability of high-resolution satellite imagery and emerging developments in analysis techniques support the implementation of these data into coastal management, including shoreline monitoring and change analysis. Geospatial shoreline data were created from a semi-automated methodology using WorldView (WV) satellite data between 2013 and 2020. The data were compared to contemporaneous field-surveyed Real-time Kinematic (RTK) Global Positioning System (GPS) data collected by the Grand Bay National Estuarine Research Reserve (GBNERR) and digitized shorelines from U.S. Department of Agriculture National Agriculture Imagery Program (NAIP) orthophotos. Field data for shoreline monitoring sites was also collected to aid interpretation of results. This data release contains digital vector shorelines, shoreline change calculations for all three remote sensing data sets, and field surveyed data. The data will aid managers and decision-makers in the adoption of high-resolution satellite imagery into shoreline monitoring activities, which will increase the spatial scale of shoreline change monitoring, provide rapid response to evaluate impacts of coastal erosion, and reduce cost of labor-intensive practices. For further information regarding data collection and/or processing methods, refer to the associated journal article (Smith and others, 2021).

Purpose:

This dataset contains GPS points used to derive shorelines. The purpose of these data is for the calculation of shoreline change for marsh shorelines of the GBNERR from 2013-2020.

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. GPS elevation data for 2013, 2014, and 2015 was excluded due to uncertainty with data units.

Completeness_Report:

Dataset is considered complete for the information presented. GPS point data do not have complete coverage over the entire study area. GPS shorelines were only collected at specific sites as points. Shoreline collection length was estimated by each researcher, so shorelines from one date to the next might have some variation in the start location, end location, and number of points.

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. While elevation data was collected and is provided with this data, it was not used to correct other data in this study. Elevation data for 2013, 2014, and 2015 were excluded from the published files due to issues with the elevation data units and are represented as -9999.

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 was not taken into account when deriving shorelines. Published general uncertainty estimates for shorelines were used for all shorelines in this study based on the data source (satellite derived, aerial imagery, GPS). The GPS also has potential variations in shoreline positions from other published data due to variations in what the GPS data collection user interpreted as the shoreline.

GPS shoreline point data was provided by the GBNERR staff and published as part of this study as both GPS points and lines (https://doi.org/10.5066/P9W8TNQM).

Process_Step:

Process_Description:

From 2013 to 2020, coastal managers’ survey shoreline positions using Real-time Kinematic (RTK) GPS at eleven locations in GBNERR. Data were collected in the Mississippi State plane coordinate system and elevations in North American Vertical Datum of 1988 (NAVD88). Coordinates were converted to the North American Datum of 1983-Universal Transverse Mercator Zone 16N (NAD83 UTM 16N) using the ArcGIS "Reproject" tool. GPS data were collected using a Trimble R8 Model 3 Global Navigation Satellite System (GNSS) and TSC3 data collector from 2013 to 2018, or a Trimble R10 GNSS system and TSC3 data collector from 2018 to 2020. Each were attached onto a 2-meter (m) graphite rod with a mounted foot to obtain both horizontal and vertical shoreline position. The positional accuracy of Trimble R8 Model 3 GPS points was ± 10 millimeters (mm) + 1 parts per million (ppm) root mean square (RMS) horizontal error and ± 20 mm + 1 ppm RMS vertical error. The horizontal error of the Trimble R10 GPS points was ± 8 mm + 0.5 ppm RMS and vertical error was ± 15 mm + 0.5 ppm RMS. The points were collected roughly 5 to 10 meters apart along the vegetation-water boundary, which typically represented the top of an erosional scarp. In instances where an erosional scarp was not visible, the most suitable shoreline position based on dense shoreline vegetation is mapped.

Process_Step:

Process_Description:

GPS points were processed and turned into an ArcGIS shapefile using ArcGIS 10.5.1. Values were checked for accuracy. During data post processing the units used to collect elevation in 2013, 2014, and 2015 were not able to be determined, so these dates were excluded from the published data. A WorldView derived shoreline and GPS points from a date close to the WorldView were added to ArcMap. The "Near (Analysis)" tool was used to calculate the closest distance between each GPS point and the WorldView shoreline. All GPS points were merged into one shapefile, using the ArcGIS "Merge" tool, for further analysis.
