%description
Characterises the environment surrounding point locations by computing
land-cover composition within circular buffers directly from vector
polygons, without conversion to a raster grid. For each site and each
class it returns the exact surface area inside the buffer and a
distance-decay weighted "effective" area in which the kernel is integrated
over polygon geometry rather than evaluated at the polygon centroid,
avoiding the large bias the centroid approximation introduces for
elongated features passing close to the site. Polygons may overlap, so
class areas are not constrained to sum to the buffer area. Intended for
buffer-based exposure assessment and fine-scale spatial epidemiology,
where the relevant scale is tens of metres and global land-cover products
are too coarse: land-use regression around air-quality monitors, green
space around residential addresses, vector-surveillance traps, and
comparable designs. The classification dictionary is user-supplied, and
point features and distances to off-buffer reference features are recorded
alongside the areas.
