Description

List stroke points in a GEOmap

Usage

1
list.GEOmap(MAP, SEL = 1)

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.

Value

GEOmap list

STROKES

Metadata for strokes

POINTS

list, lat=vector, lon=vector
