GeoDensityR - Generate Density Rasters from Polygon and Census Data

Creates continuous density raster surfaces by joining vector spatial layers with tabular data frameworks, normalizing values by ellipsoidal polygon area calculations. Reconciles discrete boundary-constrained census or survey counts with uniform grids. Accepts spatial objects in-memory or via file paths. Methods are based on spatial rasterization workflows implemented in the 'terra' package Hijmans (2025) <https://rspatial.github.io/terra/>.
