GEOmap (version 2.1)

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)

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

Value

• Perimeter
  x,y points around the perimeter of the 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.
