lon_lat_to_cartesian R Documentation
Convert Geographic Coordinates to Cartesian Coordinates
Description
This function converts geographic coordinates, given as longitude and latitude in degrees, to Cartesian coordinates (x, y, z) assuming a spherical Earth model.
Usage
lon_lat_to_cartesian(lon, lat, R = 6371)
Arguments
lon
Numeric vector of longitudes in degrees.
lat
Numeric vector of latitudes in degrees.
R
Radius of the Earth in kilometers (default: 6371 km).
Value
A numeric matrix with three columns (x, y, z) representing Cartesian coordinates.
Examples
lon <- c(-122.4194, 0)
lat <- c(37.7749, 0)
lon_lat_to_cartesian(lon, lat)
