    <p>I concur with Wayne, Chavoux and Damian. You can thin down the
      entire dataset to get a consistent ~2 pts per day, and analyze
      that subset for its spatial characteristics only (i.e.,
      isopleths). In other words, ignore time when you construct hulls
      for this subset because the duration between observations is not
      meaningful (has less to do with the individual's behavior and more
      to do with noise from the sampling logistics). Then when you
      analyze the portion of the data that has a regular sampling
      frequency, you can include time when constructing hulls, compute
      hull metrics that assume enclosed points are near in space and
      time, construct metrics for revisitation, etc. Cheers, Andy<br>

      Just to be clear.  You can analyze the full period using a subset
      of the higher frequency data added to the full set of the lower

              <div class="">I agree with the answer by Damian Lidgard.
                As I understand it, you define a "visit" period (in
                order to see whether 2 points in the same area is part
                of a single visit or a revisit). Typically, for
                predators I used the longest period they would stay on a
                single carcass. So if your sample frequency is longer
                apart than the "visit period", there is no way to
                classify it as anything else than a revisit. I would
                analyse the 2 periods separately.</div>
