Global Coast Map

Description

Global Maps of Coast

Usage

data(coastmap)

Format

List structure:

STROKES

list(nam, num, index, col, style, code, LAT1, LAT2, LON1, LON2)

POINTS

list(lat, lon)

PROJ

list(type, LAT0, LON0, LAT1, LAT2, LATS, LONS, DLAT, DLON, FE, FN, name)

Details

This map list is used for filling in coastal lines for global maps. The style=3 is for filling in polygons. The strokes are named for easier access to particular parts ofthe globe. Asia and Africa are one stroke, as are North and South America. there are currently three codes: C=major coast, c=smaller coasts, L=interior lakes.
