CTX DEM Dataset in Arabia Terra

MRO CTX Digital Elevation Models (DEMs) and Map Projected Orthoimages produced using Ames Stereo Pipeline. File names start with the two CTX image IDs as defined in the PDS joined with an underscore used to make the DEM, with the first image corresponding to the image with the lower emission angle. File spatial resolutions (meters per pixel) are reported after the processing stages "_map_ba_align_" section as "_meters-". Files ending with "DEM-adj.tif" postfix are the DEMs, while the map projected orthoimages end with "DRG.tif"本数据集为采用艾姆斯立体处理流水线（Ames Stereo Pipeline）生成的火星勘测轨道飞行器（Mars Reconnaissance Orbiter, MRO）背景相机（Context Camera, CTX）数字高程模型（Digital Elevation Models, DEMs）与地图投影正射影像。其文件名以用于生成DEM的两张CTX图像ID（按行星数据系统（Planetary Data System, PDS）定义）拼接而成，拼接符为下划线，且首张图像为发射角更低的影像。文件的空间分辨率（单位：米/像素）标注于处理流程阶段"_map_ba_align_"之后，格式为"_meters-"。以"DEM-adj.tif"为后缀的文件为数字高程模型，而地图投影正射影像的文件后缀为"DRG.tif"。
