decrease sampling rate of GPS track observations
Hi Erdal, Your best shot is probably to use adehabitatLT, prepare your track as a regular trajectory (i.e. with perfectly equal time lags, and missing observations present in the trajectory), and then use 'subsample'. Look at the vignette of adehabitatLT [1] for the first steps to get a regular trajectory. Hope this helps, Mathieu.

Hi all, I have a GPS track with a sampling rate of 1 observation per second. I would like to decrease the number of observations to, for example, 1 observation per 10/20/30 sec or drop all observations between turning points. What function/package would be best suited? Thanks. Best regards, Erdal [[alternative HTML version deleted]]
