Mining area 采矿区；50.Bareland 裸土、裸岩、荒漠等；60.Grassland 草地；70.Shrubland 灌丛。基于有限样本对数据进行精度分析，分类精度约在90%以上，数据质量精度有待进一步分析。本年度获取了8个节点区域（缅甸皎漂港、仰光、吉布提、曼德勒、汉班托塔港、科伦坡港、泰中罗勇工业区、曼谷）2017年10m分辨率的土地利用/覆被数据。","doi":"","projection":"","language":"zh","share_type":"online","east":110.9,"west":-3.31,"south":-1.09,"north":58.68,"scale":null,"crs":null,"filesize":2870.0,"share_policy":"a","ts_created":"2019-01-05T23:33:34.435644+08:00","doi_type":"国际公开共享数据","ts_updated":"2021-04-19T14:56:57.142114+08:00","time_description":"","datas_group":3,"time_description_en":"","data_format":null,"project":[11],"specials":["f2a78cde-1c98-4241-94dc-7532eba32b80"],"cite":null,"review_status":5,"review_invite":[{"user_name":"马明国","username":"mmgswu","email":"mmg@swu.edu.cn","is_cancel_expert":false}],"review_editor":{"id":42421,"last_login":"2022-04-08T15:16:51.670544+08:00","username":"任慧霞","email":"510727846@qq.com","is_active":true,"is_staff":true,"user_name":"任慧霞"},"data_sources":"","temporal_resolution":"Yearly","spatial_resolution":"m","license":"Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)","fund":[6],"subtopics":{"metadata":"38457695-acd6-4a3c-99a7-acab2532425c","three_pole":null,"third_pole":"XDA20030302"},"username":"XDA20030302","review_time":null,"protected_duration":6,"protected_describe":null,"is_important":false,"hit_count":1625}
