GEOmap (version 2.5-11)

list.GEOmap: List stroke points in a GEOmap

Description

List stroke points in a GEOmap

Usage

list.GEOmap(MAP, SEL = 1)

Value

GEOmap list

STROKES

Metadata for strokes

POINTS

list, lat=vector, lon=vector

Arguments

MAP

GEOmap list, with LL list

SEL

index, selecttion of specific strokes

Details

Returns a GEOmap list from the output of GEOmap.list . This is used to repack a GEOmap list. Tis function can be used to create a new geomap if you have only strokes. See example. Can be used to convert a gmt map file (in ascii text format) to GEOmap.

Examples

data(coastmap)

length(coastmap$STROKES$nam)

G = GEOmap.list(coastmap, 1)

length(G$STROKES$nam)

H = list.GEOmap(G)

length(H$STROKES$nam)

plotGEOmap(H)

##############   if you have a set of simple strokes
#####  make your own geomap:
