Georeferenced KH-9 Imagery - Quang Tri

This dataset contains georeferenced KH-9 images used in the manuscript "Detecting Vietnam War bomb craters in declassified KH-9 satellite imagery" (in submission). It contains the following images, provided as .tif files at a resolution of one meter per pixel (1mpp), as used in the analysis, and eight meters per pixel (8mpp): D3C1205-100113A009, D3C1205-100113A010, D3C1205-100113A011, D3C1205-100113A012. The quang-tri-aft-1mpp.tif file is a mosaic of the georeferenced images (1mpp), cropped at the extents of Quang Tri province. The KH-9 images were acquired on the 20. March 1973 by a HEXAGON KH-9 reconnaissance satellite and cover parts of Viet Nam and Lao PDR. The original images (not georeferenced) were provided as part of the Declassified Satellite Imagery - 3 collection (https://doi.org/10.5066/F7WD3Z10) courtesy of the U.S. Geological Survey.

本数据集收录了用于已投稿论文《在解密KH-9卫星影像中识别越南战争弹坑》（"Detecting Vietnam War bomb craters in declassified KH-9 satellite imagery"）的地理参考KH-9影像。
本数据集包含两类分辨率的TIFF（.tif）格式影像，分别为本研究分析所用的1米每像素（1mpp）版本，以及8米每像素（8mpp）版本，具体影像编号为：D3C1205-100113A009、D3C1205-100113A010、D3C1205-100113A011、D3C1205-100113A012。
文件quang-tri-aft-1mpp.tif为上述地理参考1mpp影像的镶嵌图，已裁剪至广治省的范围。
这批KH-9影像由HEXAGON KH-9侦察卫星于1973年3月20日获取，覆盖越南及老挝人民民主共和国部分区域。
原始未经过地理参考的影像作为"解密卫星影像-3"（Declassified Satellite Imagery - 3）馆藏的一部分，由美国地质调查局（U.S. Geological Survey）提供，相关DOI链接为https://doi.org/10.5066/F7WD3Z10。
