Abstract:
Shorelines Extracted from 1984-2015 Landsat Imagery: Ship Island, Mississippi (Polyline: Combined Dates) is a line shapefile representing shorelines generated from satellite imagery that was collected from 1984 to 2015. The sample frequency of satellite imagery is much higher, and the coverage much greater, than most routine high-resolution topographic surveys. Certain aspects of barrier island morphology, such as island size, shape and position, can be determined from these images and can indicate erosion, land loss, and island breakup. Studying how these characteristics evolve will help develop an understanding of how barrier islands will respond to climate change, sea level rise, and major storms in the future and that will serve to improve management of coastal resources.
Purpose:
To document the Ship Island, Miss. shorelines, from March 25, 1984 to May 23, 2015 as observed from Landsat 5 Thematic Mapper (TM), Landsat 7 Enhanced Thematic Mapper Plus (ETM+), and Landsat Operational Land Imager (OLI) satellite imagery. These data will aid in developing an understanding of the change in barrier island size, shape and position, which can indicate erosion, land loss and island breakup. This dataset, ship_lines_combined_dates.zip, and others are included in a USGS Data Release, which can be accessed online at https://doi.org/10.5066/meta.txtCD.

Use_Constraints:
None. However, variability in image quality from one date to another, from one image to another on the same date, and from one part of a single image to another part of the same image, exists due to many factors including variation in sun angle, atmospheric conditions, season, reflectivity of the earth surface, camera angle, camera lens, camera settings, film sensitivity, water turbidity, water depth, tide level, waves, and error in image rectification. No adjustments were made to account for tide level.

Acknowledgment of the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center Coastal and Marine Geology Program (SPCMSC), as a data source would be appreciated in products developed from these data, and such acknowledgment as is standard for citation and legal practices. Sharing of new data layers developed directly from these data would also be appreciated by the U.S. Geological Survey staff. Users should be aware that comparisons with other datasets for the same area from other time periods may be inaccurate due to inconsistencies resulting from changes in photointerpretation, mapping conventions, and digital processes over time. These data are not legal documents and are not to be used as such.
Native_Data_Set_Environment:
Microsoft Windows 7 Version 6.1 (Build 7601) Service Pack 1; Esri ArcGIS 10.2.2.3552.
Data_Quality_Information:
Logical_Consistency_Report:
Variations in image quality and in atmospheric and surface conditions may have affected the quality of the shorelines. Tide levels vary from image to image which affects the apparent shoreline. No adjustments were made for varying tide levels.
Completeness_Report:
This dataset is considered complete for the information presented, as described in the abstract section. Users are advised to read the rest of the metadata record carefully for additional details. Landsat 7 ETM+ images after May 2003 were not used due to striping caused by the failure of the instrument's scan-line corrector. No shorelines were created for 2012 due to poor Landsat 7 image quality.

Process_Step:
Process_Description:
Landsat 5 Thematic Mapper (TM), Landsat 7 Enhanced Thematic Mapper Plus (ETM+), and Landsat 8 Operational Land Imager (OLI) satellite imagery were acquired in digital format from the U.S. Geological Survey Global Visualization Viewer (http://glovis.usgs.gov/). Images were selected based on cloud-free areas of interest. Landsat 7 ETM+ images after May 2003 were not used due to striping caused by the failure of the instrument's scan-line corrector. The Landsat images were processed using ArcGIS. Images were subset (trimmed) to the area of interest and isolines were generated based on the numerical values of band 7. Band 7, an infrared band (2.08-2.35 µm for TM, 2.09-2.35 µm for ETM+, 2.11-2.29 µm for OLI), clearly distinguishes land from water due to the absorption of these wavelengths by water (Lillesand and Kiefer, 1987) resulting in a low reflectance in contrast to the higher reflectance of land areas, particularly sand. Each isoline was visually compared with its corresponding image and the isoline that best represented the land/water line was selected to represent the shoreline and saved to a shapefile. The individual date shapefiles were combined into one combined date shapefile. Wet, marshy shorelines were less reliably delineated using this method and varied more with tide level than the sandy shorelines. When necessary, small hand edits were made to the selected isolines. Predicted tide levels relative to Mean Lower Low Water (MLLW) from the Dauphin Island, Ala. tide station were obtained from a tide and current prediction program, WXTide32, (www.wxtide32.com) and added as an attribute to ship_ln_19840325_20150523.shp. No adjustments were made to the shorelines for varying tide levels.
