In order to discover an alternative solution of low resolution of land use pixels, a new methodology is used in subpixel mapping. Vectorial Boundary-based Subpixel Mapping (VBSPM) method and downscaling factors from 2 to 10, as well as 6-24 land use classification system were used in this experiment. Multi-scale (spatial resolution) land use map with resolution between 500m and 100m was acquired separately by using classified fraction information(1000m) of two hierarchical categories of land use map of Jingjinji region in 2005. The dataset is consisted of experiment result data in two parts, one is the first level of land use classification system in 6 land use types, and the second is 24 land use types in the second level of land use classification system. The data is archived in .tiff data format with the size of 23.9MB. Detail information and analysis paper was published at the journal of Remote Sensing, No.5, Vol. 8, 2016.
