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 Initiative. The production of Digital Orthophoto Map(DOM) dataset is made up of high-resolution GF-1 and GF-2 satellite images. 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. It contains panchromatic and multispectral fusion images in TIFF format, with a 2-m spatial resolution. The maximum error of orthorectification correction is 0.35 pixel in the X direction, and 0.4 pixel in the Y direction, while that of root mean square is 0.42 pixel in the X direction, and 0.38 pixel in the Y direction. PanSharpening method is used to fuse these high-resolution images. This dataset can enrich the spatial basic data resources of the region and can be used as basic data for infrastructure planning, natural disaster early-warning and ecological safety evaluation along the China–Pakistan Economic Corridor.
