Species Distribution Modeling with H3 Grids
Overview
Provides tools for species distribution modeling using H3 hexagonal grids (Uber Technologies Inc., 2022, https://h3geo.org). Facilitates retrieval of species occurrence records, generation of H3 grids, computation of landscape metrics, and preparation of spatial data for modern species distribution models workflows. Designed for biodiversity and landscape ecology research.
Improvements
h3sdm_aoa()no longer depends onvip. Variable importance forrangerandxgboostmodels is now extracted directly viaranger::importance()andxgboost::xgb.importance(), removing an external dependency aftervipwas archived from CRAN on 2026-07-13. Behavior is unchanged: importance weighting still uses each engine's native (non-permutation) importance measure.h3sdm_workflow()andh3sdm_workflows()now warn when arangermodel spec is created without an importance mode (e.g.set_engine("ranger", importance = "impurity")). Without it,h3sdm_aoa()silently falls back to equal variable weights instead of weighting by native importance.
