New function track_query() similar to track_intermediate() but for arbitrary points in time. In-development.
New function track_intermediate() to perform interpolation along a great circle between input locations. The interpolation step may be set by distance or duration and date-time is interpolated if included.
Metres, seconds, degrees, everywhere.
Fixed Value documentation for various functions, thanks to CRAN feedback.
New functions track_time, track_speed,track_distance_to() and track_bearing_to().
Added basic functions track_distance, track_angle, track_turn, and track_bearing.
