Stationary period (stap) is a key concept of the GeoPressureR workflow which descritize the trajectory of a bird in time and space. During a single stap, the bird is assumed to remain at the same location (+/- tens of kilometers). flight is the ‘converse’ of stap, with flight.start corresponding to an stap.end and reciprocly.

stap are typically estimated by GeoPressureR::tag_label_stap() based on the labels 'flight' assigned to the pressure or acceleration measurements (measurements.label). See the GeoPressureManual for more details.
