航卫照片、卫星照片和陆地摄影照片,真实地、集中地反映了较大范围内的岩土类型,地质结构、地貌、水文地质条件和物理地质现象,详细判释研究能给人一个宏观的总体认识。近年来国内外都已经渐渐将其应用于工程地质测绘,特别是用语研究区域稳定性、道路选择和滑坡等不良现象,实践证明效果是良好的。尤其是在人烟稀少、交通不便的偏远山区进行工程地质测绘,运用航卫片就更有特殊的意义,它能起到减少测绘工作量、提高测绘精度和速度的作用,
Aerial photos, satellite photos and photos of terrestrial photographs truly and collectively reflect the geotechnical types, geological structures, topography, hydrogeological conditions and physical geology in a large area. Detailed interpretation research can give a macro Overall understanding. In recent years, both at home and abroad have gradually applied it to engineering geology surveying and mapping, especially the terminology research on the regional stability, road selection and landslide and other adverse phenomena, the practice proved that the effect is good. Especially in sparsely populated and inaccessible remote mountainous areas for engineering geological mapping, the use of aerial photos is more special significance, it can reduce the workload of surveying and mapping, mapping accuracy and speed to improve the role,
