compute_dist_cross_track: compute spherical cross track distance (error)

In mitre/earthtools: Tools for working on planet Earth

Description

This function provides a convienant wrapper to dist2gc. Per that documentation, this measures the distance from the input point(s) defined by latitude and longitude to the nearest location on the great circle path defined by the path_* inputs.

Usage

compute_dist_cross_track(latitude, longitude, path_latitude1,
  path_longitude1, path_latitude2, path_longitude2)

Arguments

latitude	numeric vector of latitudes [degrees]
longitude	numeric vector of longitudes [degrees] corresponding with latitude
path_latitude1	numeric vector of latitudes [degrees]
path_longitude1	numeric vector of longitudes [degrees] corresponding with path_latitude1
path_latitude2	numeric vector of latitudes [degrees]
path_longitude2	numeric vector of longitudes [degrees] corresponding with path_latitude2

Value

numeric, cross track distance nautical miles
