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.
