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
