Introduction

Voronoi Hull Model is a geographical model that uses the location of known occurrences and predicts that a species is present inside voronoi hulls around observed occurrences, and absent outside those hulls. To create a Voronoi hull, a polygon is drawn around each known location, which consists of all points whose distance to the known location is less than or equal to its distance to any other known location. 

This model does not use the input of environmental variables to predict the distribution of a species.


Advantages

  • Relatively simple and easy to interpret

Limitations

  • Does not use environmental variables to predict species occurrence

Assumptions

N/A


Requires absence data

Yes

Configuration options

BCCVL uses the ‘dismo’ package. There are no configuration options for this algorithm.
