The 2011 land use / land cover data set of Heihe River Basin adopts the same hierarchical land cover classification system as the previous land cover data of Heihe River Basin, which divides the whole basin into 6 first-class categories (cultivated land, forest land, grassland, water area, urban and rural residents, industrial and mining land and unused land) and 25 second-class categories; The data type is vector polygon, which is stored in shape format.
|collect time||2011/01/01 - 2011/12/31|
|collect place||Middle reaches of Heihe River Basin|
|data size||22.9 MiB|
Based on the landsatm and ETM Remote Sensing Data in 2011, combined with field investigation and verification, the 1:100000 land use / land cover image and vector database of Heihe River Basin were established by the Remote Sensing Research Office of Institute of cold and drought, Chinese Academy of Sciences.
Landsatm and ETM Remote sensing data are verified in combination with field investigation p>
