This function calculates an occurrence distribution from telemetry data and a continuous-time movement model using Kriging. This means that it optimally infers the complete movement path from a limited sample of locations.
After fitting a continuous-time movement model, this app allows to reconstruct the path where the animal possibly went.
For details and background of the method please see the publication and the methods description in the documentation of the occurance function of the ctmm package. The occurrence distribution attempts to calculate the track of the animal, while the range distribution (i.e., the result of the aKDE app) calculates the long-term space use.
The app requires a ctmm model with data as input.
ctmm UD with Data and Model including the occurrance distribution.
occurrence.gpkg: A geopackage with the calculated occurrence distributions at the selected isopleths.
occurrence_uds.zip: A zipped archive of individual occurrence distributions (saved as tifs).
Isopleth level: Coverage level of the utilization distribution area.
Opacity: The opacity (or non-transparency) of the estimated home range on the map.
Remove all animals from map: This button will remove all home-ranges from the map. They can be added individually again.
Store settings: click to store the current settings of the app for future workflow runs
Calculating of occurrence distribution can potentially take a long time if a lot of data points are available for an animal.
