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.
