TY - Data T1 - 1:100000 desert (sand) distribution data set in China A1 - YanChangzhen A1 - Wang jianhua DO - 10.12072/ncdc.Westdc.db0027.2021 PY - 2021 DA - 2021-10-29 PB - National Cryosphere Desert Data Center AB - The data set is the first 1:100000 desert spatial database in China, which is based on the graph data of desert thematic map. It mainly reflects the geographical distribution, area size, mobility and fixation degree of deserts in China. According to the system design requirements and relevant standards, the input data shall be standardized and converted into the standard format of all kinds of data input. Build the database to deliver the system to run. In this project, TM image in 2000 is used as the information source to interpret, extract and edit the coverage and 2000 TM digital image information of the national land use status map. In combination with remote sensing and geographic information system technology, and according to the mapping requirements of 1:100000 scale thematic map, thematic mapping of sand, sand and Gravel Gobi in China is carried out. The 1:100000 national desert map can save a lot of data input and editing when users are engaged in the research of resources and environment. Digital map can be easily transformed into layout mapThe dataset properties are as follows:There are two folders: E00 and SHPComparison table of desert map names and provinces in the folder01 ahsm Anhui Province02 BJSM Beijing03 fjsm Fujian Province04 gdsm Guangdong Province05 GSSM Gansu Province06 gxsm Guangxi Zhuang Autonomous Region07 gzsm Guizhou Province08 hebsm Hebei Province09 hensm Henan Province10 hljsm Heilongjiang Province11 hndsm Hainan Province12 hubsm Hubei Province13 jlsm Jilin Province14 JSSM Jiangsu Province15 jxsm Jiangxi Province16 lnsm Liaoning Province17 nmsm Inner Mongolia Autonomous Region18 nxsm Ningxia Hui Autonomous Region19 qhsm Qinghai Province20 SCSM Sichuan Province21 SDSM Shandong Province22 sxsm Shaanxi Province23 tjsm Tianjin24 twsm Taiwan25 xjsm Xinjiang Uygur Autonomous Region26 xzsm Tibet Autonomous Region27 zjsm Zhejiang Province28 shxsm Shanxi Province1.
