GlobeView: Global Plot

In GEOmap: Topographic and Geologic Mapping

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
