香港特别行政区30m土地覆被其它用地类型数据（2010年）

香港特别行政区30m土地覆被其它用地类型数据（2010年），以中国土地覆被产品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-meter land cover and other land use type dataset for the Hong Kong Special Administrative Region (2010) was completed by rasterizing the ChinaCover2010 product as the base map. ChinaCover2010 was developed using domestic Huanjing (HJ) satellite remote sensing data as the primary data source, supplemented by the Vegetation Map of the People's Republic of China (1:1,000,000 scale), land use maps from 2000 and 2005, slope and aspect data derived from ASTER DEM, and other auxiliary datasets, with object-oriented technology applied for interpretation. Its classification system includes 6 primary categories consistent with the IPCC system, while the secondary categories consist of 38 types with globally unified codes generated via FAO's Land Cover Classification System (LCCS). Currently, the classification accuracy of ChinaCover2010 reaches 91% for the primary categories and approximately 82% for the secondary categories.
