bufferscape: Distance-Weighted Landscape Composition in Buffers Around Point
Locations
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.
