– Topographic factor: Digital Elevation Model. – Navigation factor: allows to discriminate valley areas (wadi) where travelers easily orient themselves from areas with few landscaped landmarks. It was produced by analyzing the theoretical hydrographic network, itself created by DEM processing. – Terrain factor: This layer represents the difficult walking zones for a loaded camel that are the coherent outcropping rocks or coarse sedimentary deposits. It was produced by combining geological and topographical data and by photo-interpretation of satellite images. DATA PAPER

– 地形因素：数字高程模型。– 导航因素：允许区分山谷地区（旱谷），在这些地区，旅行者可以轻松地将自己与景观地标很少的地区进行定位。它是通过分析理论水文网络生成的，该网络本身由 DEM 处理创建。– 地形因素：这一层代表了装载骆驼的艰难行走区域，即连贯的露头岩石或粗糙的沉积物。它是通过结合地质和地形数据以及对卫星图像进行照片解释而产生的。资料文件
