2026-06-15 TLVCI Index and Built-Up Area Results doi:10.57760/sciencedb.39948 en This dataset is derived from the research work on the extraction of built-up areas based on multi-source remote sensing data - taking Baoding City as an example. The dataset system integrates multi-source remote sensing images and auxiliary data from the jurisdiction of Baoding City in 2020, aiming to solve the problem of vegetation confusion caused by "light overflow" in traditional nighttime light data extraction of built-up areas. The dataset includes: preprocessed NPP/VIIRS nighttime light data, Landsat 8 OLI/TIRS optical and thermal infrared data preprocessing results, and reference built-up area data with administrative division vector boundaries for accuracy verification. All raster data have been uniformly re projected to WGS1984_ Albers equal area projection, and mosaic, study area cropping, etc. have been completed, which can be used for TLVCI (Surface Temperature Nighttime Light Vegetation Constraint Index) construction.  TLVCI; built-up area; remote sensing Li Zhen RESTRICTED dataset Science Data Bank
