Spatial Subsampling of Biodiversity Occurrence Data

v1.0.1 · Apr 13, 2025 · GPL (>= 3)

Description

Divide taxonomic occurrence data into geographic regions of fair comparison, with three customisable methods to standardise area and extent. Calculate common biodiversity and range-size metrics on subsampled data. Background theory and practical considerations for the methods are described in Antell and others (2024) <doi:10.1017/pab.2023.36>.
