Topographic sheets (t-sheets) produced by the National Ocean Service (NOS) during the 1800s provide the position of past shorelines. The shoreline data can be vectorized into a geographic information system (GIS) and compared to modern shoreline data to calculate estimates of long-term shoreline rates of change. Many t-sheets were scanned and digitized by the National Oceanic and Atmospheric Administration (NOAA) and are available on the NOAA Shoreline website (https://shoreline.noaa.gov/data/datasheets/t-sheets.html). However, some t-sheets were not scanned by NOAA and are only available via the National Archives and Records Administration (NARA). The data included within this data release were previously unavailable or not published in digital format. These data were produced to provide a more comprehensive record of shoreline position for Fire Island and Great South Bay, New York, to aid geologic and coastal hazards studies. This data release includes previously unavailable georeferenced t-sheets and digital vector shorelines for the Fire Island and Great South Bay, New York, coastline from 1834, 1838, and 1874/1875. The original t-sheets were scanned by the NARA-authorized vendor and sent to the Unites States Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC) as non-georeferenced digital raster files. Upon arrival at the SPCMSC, USGS staff performed the following procedures: rasters were georeferenced, projected to a modern datum, and shorelines were digitized to create a vector polyline depicting the historical shoreline position. The t-sheets included in this data release are: 1) T-479a, T-479b, T-1 (Parts 2 and 3) (1834); 2) T-58 (Parts 1 and 2) (1838); 3) T-1374a, T-1374b, T-1375a, T-1375b (1874); and 4) T-1402 (1875). All shorelines, including the ocean-facing barrier island shoreline, back-barrier island shoreline, mainland and islands were digitized. Please read the full metadata for details on data collection, dataset variables, and data quality.
Shoreline data are considered a crucial element in performing change analysis for erosion and accretion studies and for tracking shoreline movement over time. T-Sheets were georeferenced and digitized to document the short- and long-term changes of select study areas along the Fire Island, New York, coastline. Digitized shorelines from the t-sheets provide an accurate and measurable change in shape, area, and shoreline movement over short- and long- term periods.

Acknowledgment of the U.S. Geological Survey, St. Petersburg Coastal and Marine Science Center, 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.

No formal attribute accuracy tests were conducted.
Digitized shorelines were checked to ensure they were continuous lines with no overlap. Shorelines were checked for dangles (or extra line segments), which were removed, when necessary. The shorelines were split into foreshore, backshore, mainland, and islands based on a visual assessment. Small islands and creeks were not digitized as they were not necessary for this study. Larger creeks and rivers were digitized as much as necessary to ensure a complete shoreline for later use within shoreline change programs.
Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.
A formal accuracy assessment of the horizontal positional information in the dataset has not been conducted.
A formal accuracy assessment of the vertical positional information in the dataset has either not been conducted or is not applicable.
T-sheet maps created for the Fire Island, New York, coastline from 1834 to 1875 were located by the United States National Archives (NARA) staff. An authorized vendor was then contracted to scan the requested topographic sheets: T-479a, T-479b, T-1 (Parts 2 and 3), T-58 (Parts 1 and 2), T-1374a, T-1374b, T-1375a, T-1375b, and T-1402. T-sheet georectification methods can be found in the accompanying t-sheet metadata. To digitize the shorelines, the georeferenced t-sheets were added to ArcMap 10.6.1. Using the ArcMap editor toolbar, the ocean-facing barrier island shoreline, back-barrier island shoreline, mainland, and islands were digitized based on a visual assessment of shoreline locations within the imagery at a scale of 1:1500. For consistency, some small islands and creeks were not digitized, since they were not necessary for the shoreline change analysis.
