Data
Building data:building footprint,building height
Street data
Topography data
Land use data 15 m-resolution
Remote sensing images
Analysis of spatial autocorrelation
Spatial autocorrelation reveals the geographical phenomenon that things closer display more similarity than those further away
确定grid大小
Kolmogorov–Smirnov test
Kolmogorov–Smirnov test (K-S test) is a nonparametric test to examine whether two datasets differentiate significantly.
to determine if different geolocations of the raster grid system influence the statistics of LCZ classification criteria
GIS-based LCZ classification and urban geometric analysis
Development of land surface analysis maps for LCZ classification
Building height (BH) map
Building height is mean building height of an LCZ grid, weighted with the footprint area of buildings.
Building surface fraction (BSF) map
compact or open
Sky view factor (SVF) map
Aspect ratio/height width ratio (H/W) map
Pervious surface fraction (PSF) map
Impervious surface fraction (ISF) map
Land use (LU) map
the BH map and BSF map were used to identify the building-type LCZ classes
seven land cover types have been classified according to the dominant land cover types
