2020年中西亚30m Landsat TM/OLI湖泊分布数据集

该湖泊产品覆盖范围涵盖中亚五国、西亚土耳其、阿富汗及伊朗全境，该产品使用Landsat、SPOT数据遥感数据解译得到，其中大部分区域使用Landsat数据，部分重点监测区域采用SPOT数据进行补充，利用多源、多时相遥感影像，结合遥感参数、地形地貌和自然环境因子，采用面向对象的遥感分类方法，应用影像分割、决策树分类、变化监测等关键技术完成。该2020年30米空间分辨率数据可用于中西亚湖泊时空变化分析及资源利用评估，可为农牧业、林业、环境保护、水资源保护、环境保护等政府相关部门的规划与管理提供基础信息。

This lake product covers the five Central Asian countries, as well as the entire territories of Turkey, Afghanistan and Iran in West Asia. This product is derived through remote sensing data interpretation using Landsat and SPOT datasets. Most regions are covered with Landsat data, while key monitoring areas are supplemented with SPOT data. It is completed by leveraging multi-source and multi-temporal remote sensing images, combining remote sensing parameters, topography, geomorphology and natural environmental factors, adopting object-oriented remote sensing classification methods, and applying core technologies including image segmentation, decision tree classification and change detection. This 30-meter spatial resolution dataset from 2020 can be used for spatio-temporal change analysis of lakes in Central and West Asia and resource utilization assessment, providing basic information for the planning and management of relevant government departments involved in agriculture, animal husbandry, forestry, environmental protection and water resources conservation.
