资源简介：
This data set includes 30 m farmland and bulidingland distribution products in Qilian Mountains in 2018. The product is based on Landsat-8/OLI data. In the production of farmland products, the Normalized Difference Vegetation Index (NDVI) is used, and the production rules are set by using the prior knowledge of crop phenology and planting types. In the production of buildingland products, the normalized NDVI is used by using the Landsat series data synthesized in summer. other indexs like NDBI, MNDWI and other data like DEM, lighting data are used together to set product production rules. The accuracy of the products of farmland andbuildingland in 2018 is 90.05% and 90.97% respectively, based on the high-definition image of Google Earth and field survey data.
