Calculate great circle distance and bearing between coordinates

Calculate great circle distance and bearing between spatial coordinates.

lonlat_to_bearing(origin_lon, origin_lat, dest_lon, dest_lat)

Arguments

origin_lon	The origin longitude
origin_lat	The origin latitude
dest_lon	The destination longitude
dest_lat	The destination latitude

Examples

# one degree longitude should equal approximately 111km at the equator
lonlat_to_bearing(0, 0, 1, 0)
#> $bearing
#> [1] 90
#> 
#> $gc_dist
#> [1] 111.1949
