LGN6_5 (National Land Use File 6_5)

The LGN6_5 file is a land-covered grid file with a resolution of 25 meters in which 39 forms of land use are distinguished. The stock distinguishes the main agricultural crops, a number of nature classes and urban classes. The LGN6_5 file is based on the LGN6 raster file in which LGN6 has been replaced with the land use of LGN5 at the location of land use changes (between LGN5 and LGN6). The purpose of the file is to better compare land use statistics between LGN5 and LGN6.LGN6_5文件是一种空间分辨率为25米的土地覆盖栅格文件(land-covered grid file)，可区分39种土地利用(land use)类型。该文件的分类体系涵盖主要农作物、多类自然地类(nature classes)与城镇用地类(urban classes)。LGN6_5文件基于LGN6栅格文件制作，在LGN5与LGN6两个版本间发生土地利用变化的区域，将原LGN6的土地利用数据替换为LGN5的对应土地利用数据。该文件的研制目的为实现LGN5与LGN6版本间土地利用统计数据的更优对比。
