Method: measure_physical_change() — same unmodified function used across every site in this program, real LiDAR/3DEP epochs via the public hobuinc/usgs-lidar EPT index, calibrated against a stable-terrain control ring. Synthetic 200x200m buffer on the LMOP-declared coordinate — never the legal parcel boundary. Full method: /products/physical-change/.
