GlobeView {GEOmap}R Documentation

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)

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

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
