2020年中西亚30m Landsat TM/OLI耕地分布数据集

该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。新疆生地所课题组目前完成2020年30米空间分辨率数据产品。该数据集可用于中西亚耕地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 product covers the five Central Asian countries, Turkey in West Asia, as well as the entire territories of Afghanistan and Iran. It is developed through remote sensing interpretation using Landsat and SPOT datasets, where most regions adopt Landsat data while key monitoring areas are supplemented with SPOT data. The product is finalized by leveraging multi-source and multi-temporal remote sensing imagery, integrating remote sensing parameters, topographic and geomorphic features, and natural environmental factors, adopting object-oriented remote sensing classification methods, and applying core technologies including image segmentation, decision tree classification and change detection. The research team from the Xinjiang Institute of Ecology and Geography (XJIEG) has currently completed the 30-meter spatial resolution data product for the year 2020. This dataset can be used for spatiotemporal change analysis of arable land and resource utilization assessment in Central and West Asia, and provides fundamental information for the planning and management of relevant government departments in agriculture, animal husbandry, forestry, environmental protection, water resources conservation and environmental protection.
