Satellite view / polar stereographic

Description

Produces polar stereographic maps / satellite views. stereogr is simpler, newer, and faster then satellite.

Usage

stereogr(map.obj,NH=TRUE,lat.0=0,inv.col=FALSE,levels=NULL,sym=TRUE,dr=0.01,main=NULL)
satellite(map.obj,col="black",lwd=2,lty=1,add=FALSE,
                      las = 1,lon.0=NULL,lat.0=NULL,method="normal",
                      ni=100,nj=100,n.nearest=4,max.dist=3,landdata=addland2)

Arguments

map.obj a map object (mapField).
col contour colours.
lwd contour line width.
lty contour line style.
add FLAG: true adds contour onto old plot.
las see par.
lon.0 Reference longitude: centre of map; NULL selects automatically.
lat.0 Reference latitude: centre of map; NULL selects automatically.
method A choice between "normal","polarstereo", and "distance".
ni Number of grid points along x-axis in new grid.
nj Number of grid points along y-axis in new grid.
n.nearest Number of points to use in re-gridding.
max.dist The maximum inter-point distance used for re-gridding.
landdata "addland" gives hiher resolution for coast lines, but is slower.
inv.col Inverse color scheme.
NH Northern Hemisphere?.
levels contour/shading levels.
main Main title - see plot.
sym symmetric colour scale?.
dr used for masking interpolated values in data voids. Look of result may be sensitive to spatial grid resolution.
