Description:
Abstract:
Sandy ocean beaches are a popular recreational destination, often surrounded by communities containing valuable real estate. 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.

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 a reference baseline used by the Digital Shoreline Analysis System (DSAS) to calculate rate-of-change statistics for the state of Oregon. This baseline layer serves as the starting point for all transects cast by the DSAS application. The transects intersect each shoreline and establish measurement points used to calculate shoreline-change rates.

Rates of long-term and short-term shoreline change were generated in a GIS using the DSAS version 4.2- An ArcGIS extension for calculating shoreline change: U.S. Geological Survey Open-File Report 2008-1278, Thieler, E.R., Himmelstoss, E.A., Zichichi, J.L., and Ergul, Ayhan.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The attribute in this layer is based on the requirements for use within the Digital Shoreline Analysis System (DSAS) software (USGS Open-File Report 2008-1278). The data have been quality checked.
Logical_Consistency_Report:
The single polyline has a unique identification attribute (ID) of 1. This field is used by the Digital Shoreline Analysis System (DSAS) to designate the alongshore order of baselines if there are more than one.
Completeness_Report:
This baseline file is complete and contains the single baseline segment used to cast transects along sections of the Oregon coastal region where lidar shoreline position data were available and additional shoreline data are present to calculate either a short- or long-term rate.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The baseline serves as a reference point for transects cast by the Digital Shoreline Analysis System (DSAS) software. It does not correspond to any real-world feature.

Process_Description:
A baseline was constructed offshore from the time series of shoreline positions using standard editing tools in ArcMap v9.3. The baseline was positioned to conform to changes in the combined orientation of the shorelines alongshore. This was done so that the transects, which are generated by the Digital Shoreline Analysis System v4.2 from the baseline, would intersect perpendicular to the general trend of the shorelines. The baseline feature was constructed along sections of the coast containing sandy shoreline features greater than 1 kilometer in length that met at least one of the following requirements: 1) they contained the two shorelines required to compute short-term (~30 year) shoreline change analysis (a shoreline from the 1960s and the lidar-derived shoreline from 2002); or 2) they contain at least four shorelines, one of which must be the lidar-derived shoreline from 2002, that can be used to compute long-term (~130 year) shoreline change rates.
