cartesian2sphere: Convert Cartesian coordinates to spherical coordinates

In metno/esd: Climate analysis and empirical-statistical downscaling (ESD) package for monthly and daily data

Convert Cartesian coordinates to spherical coordinates

Description

Convert Cartesian coordinates to spherical coordinates

Usage

cartesian2sphere(lon, lat, lonR = NULL, latR = NULL, verbose = FALSE)

Arguments

lon	A numeric vector of longitudes
lat	A numeric vector of latitudes
lonR	Center longitude of viewing angle
latR	Center latitude of viewing angle
verbose	a boolean; if TRUE print information about progress

Value

A list(X=X, Y=Y, Z=Y) where X is the radial distance, Y is the polar angle, and Z is the azimuthal angle. When displaying data on a spherical grid, the longitude/latitude coordinate system is replaced with X/Z, i.e., plot(X, Z) instead of plot(lon, lat).
