Driving factors and information.

Type	Factor^a	Formula	Variable description	Description
Natural	DEM			Average elevation per grid (unit: m)
	NDVI		and represent reflectance in red and near-infrared bands	Average NDVI per grid
	MNDWI		and represent reflectance in green and midinfrared bands	Average MNDWI per grid
Social	NUMPOI			Number POI per grid
	Av		n represents plot number, Fi represents base area of building i, A represents grid area	Proportion of building base area per grid

^aDEM, digital elevation model; NDVI, normalized difference vegetation index; MNDWI, modified normalized difference water index (MNDWI); NUM_POI, point-of-interest number; , building-coverage ratio.
