Data: Shorelines of the World (Normal Resolution)

Description

PolySet of polygons for the global shorelines.

Usage

data(worldLL)

Format

Data frame consisting of 4 columns: PID = primary polygon ID, POS = position of each vertex within a given polygon, X = longitude coordinate, and Y = latitude coordinate. Attributes: projection = "LL".

Note

In R, the data must be loaded using the data function.

Source

Polygon data from the GSHHS (Global Self-consistent, Hierarchical, High-resolution Shoreline) database gshhs_l.b.
