Abstract：

Authors integrated Landsat TM/OLI images in 2010, 2020, Point of Interest in Baidu e-Map to create a comprehensive index (POI & ISA) and to obtain the boundary dataset of built-up areas in Chengdu-Chongqing Urban Economic Circle based on POI & ISA Composite Index (2010, 2020). The dataset includes the spatial data and statistical area data of built-up areas of 16 cities in 2010 and 2020. The dataset is archived in .shp and .xlsx data formats, and consists of 257 data files with data size of 974 KB (Compressed to one file with 611 KB).
