1 # flightpathr 2 3 Tools to analyze aircraft and flight path data. 4 5 Right now there's only one really useful function, `distanceFromPath()`. This 6 measures the distance between an actual flight track (a matrix of long/lat data 7 at each time point) and a flight path (a matrix of long/lat data at each 8 waypoint). Horizontal and vertical distance are returned separately. 9 10 The helper function `maxDistanceFromPath()` finds the horizontal and vertical 11 distance at the point of maximum "slant range" (i.e., Euclidean distance).
