GlobeView {GEOmap}

Global Plot

Description

Plot global view of the earth

Usage

GlobeView(phicen, lamcen, worldmap, MAXR, SEL = 1,
circol = rgb(1, 0.8, 0.8), innercol = "white", linecol = rgb(0, 0, 0),
 mapcol = rgb(0, 0, 0), backcol = "white", add=FALSE, antip=TRUE)

Arguments

phicen

Latitude

lamcen

Longitude

worldmap

Map List

MAXR

Maximum radius (degrees)

SEL

Selection index from map

circol

color for concentric circles

innercol

inner color

linecol

line color, NA=do not plot

mapcol

map fill color, NA=do not fill polygon

backcol

background color

add

logical, FALSE means start a new plot

antip

logical, default=TRUE means white out area outside of polygon

Details

Creates a plot of view of the globe from a point in space using an Equal-Area projection. Uses the lamaz.eqarea routine for projection. (Lambert-Azimuthal Equal Area). Using NA for linecol or mapcol means do not plot lines or fill polygons respectively.

Value

Perimeter

x,y points around the perimeter of the plot
