GlobeView: 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)

Value

Perimeter

x,y points around the perimeter of the plot

Arguments

phicen

Longitude

worldmap

Map List

MAXR

Maximum radius (degrees)

SEL

Selection index from map

circol

color for concentric circles

innercol

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.
