摘要:中巴经济走廊是“一带一路”战略大局的重要组成部分,对“一带一路”战略实施发挥着重大的示范和推动作用。通过遥感技术开展走廊沿线自然资源调查、生态环境安全评价、地质灾害动态监测及风险防控等领域研究,为重大基础设施规划、建设提供强有力的空间信息保障,而高分辨率正射影像是专题信息获取和成果表达的重要本底数据。基于高分一号、高分二号国产卫星影像制作正射影像数据集将会丰富本区域空间基础数据资源,同时挖掘国产卫星影像的应用潜力。本数据集空间范围为23°54′N–39°12′N、71°24′E–76°48′E,中巴公路两侧约60 km,中国喀什地区至巴基斯坦伊斯兰堡段,时间范围为2013–2017年,全色与多光谱2 m融合影像,TIFF格式。本数据集可应用于中巴经济走廊基础设施建设规划、自然灾害预警、生态安全评价等。

Abstract & Keywords
Abstract: The China–Pakistan Economic Corridor is an important part of the Belt and Road. Its implementation plays an important role in the demonstration and promotion of the Belt and Road. By performin natural resources survey, ecological environment safety assessment, dynamic monitoring and risk prevention of geological hazards along the corridor, remote sensing technology can provide spatial information support for major infrastructure planning and construction. High-resolution DOM image constitute an important basis for special information acquisition and result visualization. While exploiting the application potential of domestic GF satellite images, the production of DOM datasets based on high-resolution GF-1 and GF-2 satellite images also enriches spatial data resources of the region. This dataset has a spatial coverage of 23°54'N ~ 39°12'N, 71°24'E ~ 76°48'E, which is within 60km on both sides of KKH (Kashgar to Islamabad), and a temporal span from 2013 to 2017. The data are stored in TIFF format, made up of panchromatic and multispectral fusion images with 2m spatial resolution. The dataset can be used as basic data for infrastructure construction planning, natural disaster early warning and ecological safety evaluation along the China–Pakistan Economic Corridor.
