Mean proximity index
WebA proximity index (PX) inspired by island biogeography theory is described which quantifies the spatial context of a habitat patch in relation to its neighbors. The index distinguishes … WebTo do so, the input parameters are: Input layer: the point layer whose geometry we want to convert. In this example we use the places_clip layer. New geometry type: select Centroids. Converted: the path and the name of the output vector layer. Note that if left empty a temporary layer will be created.
