华东地区30m土地覆被数据（2010年）

华东地区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%。30 m Land Cover Dataset of East China (2010) was completed via rasterizing the 2010 land cover product (ChinaCover2010) as the base map. ChinaCover2010 takes domestic Huanjing (HJ) satellite remote sensing data as its main data source, supplemented by the Vegetation Map of the People's Republic of China at a scale of 1:1,000,000, land use maps of 2000 and 2005, as well as slope and aspect data derived from ASTER DEM, among other auxiliary datasets. The interpretation of this product was implemented using object-oriented technology. The first-level classification categories of the dataset are consistent with the IPCC system, totaling 6 types. The second-level categories adopt 38 types with globally unified codes generated by FAO's Land Cover Classification System (LCCS). Currently, the accuracy of the first-level categories of the ChinaCover2010 product reaches 91%, while that of the second-level categories is approximately 82%.
