NASA / USGS Mars Reconnaissance Orbiter (MRO) Context Camera (CTX) Targeted DTMs

As of March, 2023 the Mars Reconnaissance Orbiter (MRO) High Resolution Science Experiment (HiRISE) sensor has collected more than 5000 targeted stereopairs. During HiRISE acquisition, the Context Camera (CTX) also collects lower resolution, higher spatial extent context images. These CTX acquisitions are also targeted stereopairs. This data set contains targeted CTX DTMs and orthoimages, created using the NASA Ames Stereopipeline. These data have been created using relatively controlled CTX images that have been globally bundle adjusted using the USGS Integrated System for Imagers and Spectro...

截至2023年3月，火星勘测轨道飞行器（Mars Reconnaissance Orbiter, MRO）搭载的高分辨率科学实验（High Resolution Science Experiment, HiRISE）传感器已累计收集超过5000组定向立体像对。在HiRISE开展成像作业期间，背景相机（Context Camera, CTX）同步采集了低分辨率、大空间覆盖范围的背景影像。此类CTX成像数据同样属于定向立体像对范畴。本数据集包含依托美国航空航天局埃姆斯立体处理流水线（NASA Ames Stereopipeline）生成的定向CTX数字地形模型（Digital Terrain Models, DTMs）与正射影像。本数据集所采用的CTX影像均经过严格管控，并通过美国地质调查局（USGS）集成成像与光谱...系统完成了全球联合平差处理。

背景概述

该数据集包含火星勘测轨道飞行器（MRO）上下文相机（CTX）的定向数字地形模型（DTMs）和正射影像，通过NASA Ames Stereopipeline从经过全局捆绑调整的CTX立体对生成，以减少航天器抖动等误差。DTMs通过迭代对齐方法绝对控制到MOLA产品，确保与火星大地坐标参考框架一致，数据以CC0 1.0许可证在AWS上公开提供，并随新立体对处理而更新。
