Compute the cross-track distance from a great circle arc
Source:R/cross_track_distance.R
cross_track_distance.Rd
Compute the cross-track distance of a body, `b` (for example a ground level projection position of an aircraft), from a great circle arc determined by two geographical coordinates, `a1` and `a2` (for example an airport's runway thresholds).
Arguments
- b
the geographical coordinates (WGS84) of a body: a vector of longitude, latitude (in decimal degrees) and eventually altitude (in meters)
- a1
the geographical coordinates (WGS84) of one end of a great circle arc: a vector of longitude, latitude (in decimal degrees) and eventually altitude (in meters)
- a2
the geographical coordinates (WGS84) of the other end of a great circle arc: a vector of longitude, latitude (in decimal degrees) and eventually altitude (in meters)
