The limit of REEF is the edge of the rock or coral.
For a topographic/bathymetric edition only, if REEF is on the final compilation
provided to USGS by NOS,
If REEF is on an existing NOS chart, then capture.
Source Interpretation Guidelines
Numerous closely spaced ROCKS that form a chain along the coastline or
close to the shore are collected as REEF. (Quantified rules are TBD)
Areas within or next to REEF may be land areas, areas that uncover, or
water areas. If the Area uncovers, see FORESHORE. If the area is water,
The area next to REEF that uncovers is shown with the brown sand pattern
on topographic-bathymetric editions and with the black sand pattern on
topographic editions. For collection of these areas see FORESHORE.
REEF is collected along a line that connects the high points of the closed,
outer portion of the reef symbol.
