way points or tracks, both are commonly used in forest boundary delineation. Which one has high accuracy: taking way points at shorter interval or recording track?
The answer depends on the device. At the lowest level, both the approaches do the same. Tracking means recording waypoints at shorter interval. However some devices adjust (re-correct) some noisy waypoints (as the device suspects but may not really a noise) of the track based on many different heuristics. Some examples are the knowledge of the vessel, knowledge of the accessibility of the path and the average speed etc. Other than the heuristics, some devices may fit a curve which may not directly go through all the points but to approximate the correct track thinking the recorded points are noisy. Therefore, recording waypoints at shorter intervals will be always a good idea keeping in mind that shorter the interval leads to more the accuracy. Tracking will be easy and still a better idea with some devices which do not approximate but simply record the waypoints at the shortest possible interval by the device. If the second option is feasible with your device, the manual waypoint extraction will always give an equal or less accurate result than the tracking.
@Ravimal Bandara, Thank you very much for the answer. I find it very useful. Thank you once again!
