The Mastcam (Mast Camera) instrument onboard the NASA Curiosity rover provides an exclusive view of Mars: High‐resolution color images from Mastcam allow users to study Gale crater's geologic terrains along Curiosity's path. These ground observations complement the spatially broader views of Gale crater provided by spacecrafts from orbit. However, for a given Mastcam image, it can be challenging to locate the corresponding terrains on the orbital view. No method for locating Mastcam images onto orbital images had been made publicly available. The procedure presented here allows users to generate Mastcam image viewsheds, using ArcGIS® software, its built‐in Viewshed tool®, and public Mars datasets. This procedure locates onto Mars orbital view the terrains that are observed in a given Mastcam image. Because this procedure uses public datasets, it is applicable to available Mastcam images and to the future ones that will be acquired along the Curiosity rover's path. This procedure can be used by the public to assess scientific questions regarding Martian surface processes and geologic history. In addition, this procedure can be utilized as pedagogic GIS material by the Geosciences or Planetary Sciences communities, for enhancing students' skillsets in GIS and provide students with experience working with datasets from both orbiter and rover Mars missions.

耦合火星地面和轨道视图：使用ArcGIS®和公共数据集从好奇号流动站生成Mastcam图像的视场

NASA好奇号探测车上的Mastcam（桅杆相机）仪器提供了火星的独家视图：Mastcam的高分辨率彩色图像使用户可以沿着好奇号的路径研究Gale火山口的地质地形。这些地面观察补充了航天器从轨道提供的大风火山口在空间上的广阔视野。但是，对于给定的Mastcam图像，在轨道视图上定位相应的地形可能是一个挑战。没有公开公开将Mastcam影像定位在轨道影像上的方法。此处介绍的过程使用户可以使用ArcGIS®软件，其内置的Viewshedtool®和公共Mars数据集生成Mastcam图像视场。此过程将在给定的Mastcam图像中观察到的地形定位在火星轨道视图上。因为此过程使用公共数据集，所以它适用于可用的Mastcam图像以及将来将沿“好奇号”漫游者的路径获取的图像。公众可以使用此程序评估有关火星表面过程和地质历史的科学问题。此外，该程序可以被地球科学或行星科学社区用作教育学GIS资料，以增强学生在GIS中的技能，并为学生提供处理轨道飞行器和火星探测器任务的数据集的经验。
