Tutorial: How to run the Douglas Argos Filter in Movebank

The Argos System is used worldwide to satellite-track free-ranging animals, but location errors can range from tens of metres to hundreds of kilometres. The Douglas Argos-filter (DAF) is an algorithm that flags implausible locations based on user-defined thresholds that allow the algorithm's performance to be tuned to species' movement behaviours and study objectives. Movebank—a free online infrastructure for storing, managing, sharing and analysing animal movement data—allows Argos users to import their data, flexibly change filter parameters and view results. In this tutorial, we show you how this works.
