Development is on the rise despite the fact that coastal infrastructure is subjected to flooding and erosion. As a result, there is an increased demand for accurate information regarding past and present shoreline changes. To meet these national needs, the Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is compiling existing reliable historical shoreline data along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii under the National Assessment of Shoreline Change project. Shoreline vectors derived from historic and modern sources represent the low water mark (beach toe). There is no widely accepted standard for analyzing shoreline change. Existing shoreline data measurements and rate calculation methods vary from study to study and prevent combining results into state-wide or regional assessments. The impetus behind the National Assessment project was to develop a standardized method of measuring changes in shoreline position that is consistent from coast to coast. The goal was to facilitate the process of periodically and systematically updating the results in an internally consistent manner. Purpose: This dataset includes shorelines ranging from 1927 to 2005 in the Oahu South coastal region from Barbers Point to Sandy Beach. Shorelines were compiled from T-sheets (National Oceanic and Atmospheric Administration) and aerial photos. Historical shoreline positions serve as easily understood features that can be used to describe the movement of beaches through time. These data are used to calculate rates of shoreline change for the U.S. Geological Survey's (USGS) National Assessment of Shoreline Change Project. Rates of long-term and short-term shoreline change were generated in a GIS using the Digital Shoreline Analysis System (DSAS) version 4.2. DSAS uses a measurement baseline method to calculate rate-of-change statistics. Transects are cast from the reference baseline to intersect each shoreline, establishing measurement points used to calculate shoreline change rates. Supplemental_Information: Cross-referenced citations are applicable to the dataset as a whole. Additional citations are located within individual process steps that pertain specifically to the method described in that step.

Online_Linkage: http://www.hawaiiaviation.com/ Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The data provided here are a compilation of shorelines from multiple sources, spanning 78 years. The attributes 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: Adjacent shoreline segments of a given time period do not overlap and are not necessarily continuous. Shoreline segments of different time periods may overlap where a beach has been completely lost to erosion (hard shoreline, either permanently or intermittently). In this special case, historical shorelines from time periods with no beach are aligned to a high water mark position mapped from the most recent aerial photo mosaic showing no beach. Shorelines were quality checked for accuracy. Any slight offsets between adjacent segments due to georeferencing and digitizing error are taken into account in the uncertainty calculations included in the corresponding report (U.S. Geological Survey Open-file Report 2011-1051, available online at https://pubs.usgs.gov/of/2011/1051/ ). Completeness_Report: This shoreline file is complete and contains all shoreline segments used to calculate shoreline change rates along sections of the South Oahu coastal region where shoreline position data were available. These data adequately represented the shoreline position at the time of the survey. Remaining gaps in these data, if applicable, are a consequence of non-existing data or existing data that did not meet quality assurance standards. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Shoreline data have been acquired from 1927 to 2005, the horizontal accuracy of which varies with respect to data source from which the shorelines were digitized and the time period. Positional uncertainties for each shoreline segment are listed under the "ACCURACY" heading in the attribute table. Please visit the 'Uncertainties and Errors' section in the corresponding USGS Open-File Report ( https://pubs.usgs.gov/of/2011/1051 ) for a complete explanation of the measurement uncertainties associated with these shorelines. Lineage: Process_Step: Process_Description: Shoreline data were sought from local and national archives, libraries, and vendors in an effort to compile as many quality historical shorelines as possible for the region. T-sheets were requested from NOAA and received as scanned raster images. Processing date from 1998 to 2008.

T-sheets were rectified by NOAA on a Sun Microsystems(r) workstation using Environmental Systems Research Institute, Inc. (ESRI)(r) ArcInfo(r) version 7.2.1 software by placing at least 6 well-spaced ground control points (GCPs) on selected T-sheet graticules in geographic coordinates. Some T-sheets produced before 1930 required additional coordinate transformation information from NOAA to convert from the United States Standard Datum (USSD) to the North American Datum of 1927 (NAD27). In the Hawaiian Islands, the adoption of the NAD27 datum for mapping and the emergence of several unsupported local and island-specific datums have led to significant confusion among cartographers and surveyors. The datum transformation was applied to T-sheet graticule coordinates prior to rectification. Total Root Mean Square (RMS) error for the rectification process was maintained below 1 pixel, which is approximately 4 m at a scale of 1:20,000 and approximately 1.5 m at a scale of 1:10,000. Typically the resulting RMS was much lower than one pixel. Geo-referenced T-sheets were loaded in ArcMap version 9.3. ArcMap was used to transform received Geographic Projected data into the Universal Transverse Mercator (UTM) projection with the North American Datum of 1983 (NAD83) datum for digitizing and vector analysis. A verification of the T-sheet shoreline was carried out where possible using control marks or physical shoreline features present on the T-sheet and a reliable current image database. Where verification failed, T-sheets were re-rectified in PCI Geomatics Orthoengine version 10.1 software using ground control points on existent control stations and identifiable shoreline features. In all cases, shoreline feature verification produced a higher quality data product. Many T-sheet products used in this study were re-rectified in PCI to correct significant errors associated with incorrect projection datum definitions. Such errors would have otherwise rendered the sheets unusable. T-sheets are georeferenced using polynomial mathematical models in PCI with RMS errors < 4 m. Rectification of T-sheets is also verified by overlaying them on aerial photomosaics to compare their fit to rocky shoreline and other unchanged geological features.

Aircraft position (global positioning system locations) and orientation data (e.g., altitude, pitch, roll, and yaw) were recorded by an on-board positional orientation system (POS). The recent images are orthorectified and mosaicked in PCI Geomatica Orthoengine software using polynomial models incorporating POS data and high resolution (5m -horizontal, submeter vertical) DEMs to reduce displacements caused by lens distortion, Earth curvature, refraction, camera tilt, and terrain relief; usually achieving Root Mean Square (RMS) positional error < 2 m. Earlier aerial photographs are orthorectified and mosaicked in PCI Geomatica Orthoengine using 2005-2008 and 1998 (west and north Maui) aerial orthophoto mosaics as master images (for collecting Ground Control Points (GCPs)) and high resolution (5m -horizontal, submeter vertical) DEMs to reduce displacements caused by lens distortion, Earth curvature, refraction, camera tilt, and terrain relief; usually achieving Root Mean Square (RMS) positional error < 2 m.

Quality assessments were performed and shorelines were edited to remove any overlap between adjacent shorelines. No edge matching between adjacent shorelines was attempted. Shoreline layers were saved from .pix (PCI Geomatics geographic data format) to shapefile (.shp) to allow for analysis in ESRI ArcGIS software using Digital Shoreline Analysis System (DSAS). Shoreline layers from all sources were merged to produce a single shoreline shapefile for the coastal region. The final shoreline shapefile was coded with 4 attribute fields (ID, Shape, Date, and Accuracy) required for the DSAS, which was used to calculate shoreline change rates. The attributes reflect the source of the data and the original survey date. Processing date from 2008 to 2010.

This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Added a data landing page link as the first link in the identification section. Removed LIDAR bounding coordinates - an artifact of Esri and MP processing. Fixed date format in process steps. Minor fixes to attribute information. The distribution format name was modified in an attempt to be more consistent with other metadata files of the same data format. Added additional information to a cross-reference and fixed the online link. Attempted to modify http to https where appropriate. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.
