Nighttime Street Vitality Measurement of an Ancient City Based on Illuminance Data: A Case Study of Songpan, Sichuan
Description
This dataset provides the foundational data used to analyze the spatial distribution and driving mechanisms of nighttime street vitality in the high-altitude historic town of Songpan, Sichuan, China. The repository contains two primary files: Cleaned_Combined_Illuminance_Data.csv: Micro-scale nighttime street illuminance data collected via mobile measurement, joined with commercial interface attributes, timestamps, and seasonal tags. Invalid coordinates and null physical anomalies have been cleaned and removed. Built_Environment_Indicators.csv: Multi-dimensional physical, spatial, and functional metrics (e.g., Store Area Ratio, Isochronal Circle Area, POI densities) mapped for 25 independent street segments. These datasets support the multivariate linear regression modeling and correlation analyses detailed in the associated manuscript.
