BeachAttributes: Example Beach Attribute Polygons

Example Beach Attribute Polygons

Description

Sample beach attribute polygons for package examples. The beach attribute polygons highlight the foreshore area around each geomorphically distinct beach section. It is up to the user to define what constitutes a unique beach section. Each beach section should be characterized with field attributes columns for the foreshore slope (slope) as rise over run, the berm width (W), berm height (B) and dune height (D) in meters, the sediment grain size in millimeters (sediment) and the beach value per meter squared in dollars (V). Note that this dataset has been reduced and simplified from the original version and should only be used for demonstration purposes.

Usage

Format

A simple feature collection of eelgrass polygons.

slope

B

Numeric, berm height in meters (B).

D

Numeric, dune height (D) in meters.

sediment

Numeric, the sediment grain size in millimeters (sediment).

V
