资源简介：
基于优于2m分辨率的地表覆盖数据，结合道路、水系和区（县）政府所在地等专题数据，研发了一种高精度城市建成区自动化提取方法模型，并利用该方法自主生产获得中国337个地级以上城市2015年、2020年城市地区及建成区产品。
Based on land cover data with a spatial resolution better than 2 meters, combined with thematic data such as roads, water systems, and the locations of district and county government seats, we developed a high-precision automated extraction method and model for urban built-up areas. Using this method, we independently produced urban area and built-up area products for 337 prefecture-level and above cities in China for the years 2015 and 2020.
