Spatial Analysis and Modeling

Description

Utilities to support spatial data manipulation, query, sampling and modeling. Functions include models for species population density, download utilities for climate and global deforestation spatial products, spatial smoothing, multivariate separability, point process model for creating pseudo-absences and subsampling, polygon and point-distance landscape metrics, auto-logistic model, sampling models, cluster optimization and statistical exploratory tools.
