长江三角洲城市群30m土地覆被数据（2010年）

长江三角洲城市群30m土地覆被数据（2010年），以土地覆被产品2010（ChinaCover2010）为底图栅格化完成。ChinaCover2010是以国产环境星遥感数据为主要数据源，辅以中华人民共和国植被图（1:1,000,000）、2000和2005年土地利用图及ASTERDEM生成的坡度和坡向数据等，采用面向对象技术实现解译。
分类系统的一级类与IPCC系统保持一致共6类，二级类采用了由FAO的LCCS生成的具有全球统一代码的38个类型，目前ChinaCover2010产品精度一级类可达到91%，二级类约为82%。

The 30 m land cover dataset of the Yangtze River Delta Urban Agglomeration (2010) was completed by rasterizing the land cover product 2010 (ChinaCover2010) as the base map. ChinaCover2010 takes domestic Huanjing satellite remote sensing data as its primary data source, supplemented by the 1:1,000,000 Vegetation Map of the People's Republic of China, land use maps from 2000 and 2005, as well as slope and aspect data derived from ASTER DEM, among other auxiliary datasets. Image interpretation for this product was implemented using object-oriented technology. The first-level categories of its classification system are consistent with the IPCC system, totaling 6 types. The second-level categories adopt 38 types with globally uniform codes generated by FAO's Land Cover Classification System (LCCS). Currently, the overall accuracy of the ChinaCover2010 product reaches 91% for the first-level categories, and approximately 82% for the second-level categories.
