Description:
Abstract:
This shapefile contains polylines representing coastal bluff areas in which bluff erosion rate data has been collected.
Purpose:
This shapefile was created to combine bluff erosion rate data from disparate sources in one location.
Supplemental_Information:
This shapefile was created by identifying a bluff erosion rate and a geographic reference in largely paper-based reports. The information was then transferred to the shapefile by creating a polyline representing the alongshore geographic extent of the bluff erosion data by tracing existing shoreline shapefile. The bluff erosion shapefile was created with the intention of symbolizing different report types with a differing offsets such that geographic regions that overlap are visible.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The information captured in the attribute table comes from many different sources with varying levels of accuracy. All of the attributes associated with a feature have been collected from other reports and no analysis was completed by the originator. Thus, the accuracy of the information contained in the shapefile is only as accurate as the original data sources.
Completeness_Report:
This dataset should by no means be considered exhaustive. The data contained within was available to the originator during the period in which it was developed.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The polylines in this shapefile represent the alongshore length of coastline associated with bluff erosion rate data. They have been digitized by tracing the cooresponding coastline, with an offset, from an existing coastline shapefile. The locations of the polylines are intended to provide an approximate geographic extent of the associated data and is for representational purposes only.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
The locationsof the polylines are intended to provide an approximate geographic extent of the associated data and is for representational purposes only.
