WWII bombing crater imagery (LiDAR DTM), NW Czechia

LiDAR based imagery with different spatial resolution (0.2, 0.5, 1, 1.5, 2 m/px). Study sites in NW Czechia with remnants on WWII bombing craters. Imagery is preprocessed and postprocessed according to methods described in an article dealing with crater identification written by Dolejš and Pacina (expected publication in 1Q 2021). Data are used for crater identification algorithms testing.该数据集为基于激光雷达（LiDAR）的影像集，具备0.2、0.5、1、1.5、2 米/像素共五种空间分辨率。研究区域位于捷克西北部，区域内留存有第二次世界大战时期的轰炸弹坑遗迹。数据集所涉影像已按照Dolejš与Pacina合著的弹坑识别相关论文中所述方法完成预处理与后处理，该论文预计于2021年第一季度发表。本数据集可用于弹坑识别算法的测试与验证。
