Earth distance between two geographic locations

Description

earthDist calculates distance (in kilometers) between two lon/lat positions. The function assumes a mean equatorial Earth radius of 6378.145 km. One of the lon/lat positions (i.e. lon1 and lat1) can be a vector of positions to compare against the other lon/lat position (i.e. lon2 and lat2)

Usage

earthDist(lon1, lat1, lon2, lat2)

Arguments

lon1	Longitude 1 (in decimal degrees)
lat1	Latitude 1 (in decimal degrees)
lon2	Longitude 2 (in decimal degrees)
lat2	Latitude 2 (in decimal degrees)

Value

Vector of distances (km)

Examples

earthDist(0,0,20,20)
