bearing
- bearing(fs, lat, lon)
- bearing(fs, coords)
Computes the bearing for each grid point in
fswith reference to the given location.- Parameters
fs (
Fieldset) – input fieldsetlat (number) – latitude of the reference point
lon (number) – longitude of the reference point
coords (list) – coordinates of the reference point as [lat, lon]
- Return type
The bearing is the angle between the Northward meridian going through the reference point and the great circle connecting the reference point and the given gridpoint. It is measured in degrees clockwise from North. If a gridpoint is located on the same latitude as the reference point the bearing is regarded constant: it is either 90° (East) or 270° (West). If the gridpoint is co-located with the reference point the bearing is set to a missing value. The reference location should be specified in degrees.
