【摘要】 城市建成区可以反映城镇化进程与城市空间格局，是城市规划建设管理工作的重要基础信息，准确提取城市建成区边界对于促进城市可持续发展具有重要意义。本数据集结合城市建成区的景观及功能特征，以2010、2020年的Landsat TM/OLI影像和百度电子地图兴趣点（Point of interest,POI）为数据源，构建了建成区综合指数（POI&ISA）反映建成水平，并通过最佳阈值选取等步骤提取得到成渝地区双城经济圈16个城市建成区的实验数据集。本数据集包括成渝地区双城经济圈16个城市两期（2010,2020）实验建成区边界及面积统计数据。数据集存储为.shp和.xlsx格式，数据集由257个数据文件组成，数据量为974 KB（压缩为1个文件，611 KB）。更多还原

【Abstract】 Urban built-up area is an important basic information for urban planning and construction management, which can reflect the urbanization process and urban spatial pattern. Accurate extraction of urban built-up areas’ boundaries is of great significance for promoting sustainable urban development. We using Landsat TM/OLI images in 2010/2020 and electronic map points of interest as data source to construct a comprehensive index(POI&ISA) reflecting the build-up level of cities, then through the best threshold selection developing a proper boundary dataset of built-up areas in Chengdu-Chongqing economic circle. This dataset includes boundaries data and areas data of the built-up area in the Chengdu-Chongqing economic circle which combining the landscape and functional features. Dataset is archived in.shp and.xlsx data formats, consisting of 257 data files with data size of 974 KB(compressed into 1 file, 611 KB).更多还原
