long_lat_to_cartesian {GeoThinneR} | 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
long_lat_to_cartesian(long, lat, R = 6371)
Arguments
long |
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
long <- c(-122.4194, 0)
lat <- c(37.7749, 0)
