HiRISE DTMs generated using NASA's Ames Stereo Pipeline
收藏资源简介:
In an effort to better understand the surface roughness of Martian lava flows, we generated over 30 HiRISE DTMs using ISIS3 and ASP and extracted their roughness (Rodriguez Sanchez-Vahamonde and Neish, 2020). We have posted these DTMs for public use here. HiRISE stereo images typically have a spatial sampling of 25 - 50 centimeters, providing us with DTMs of 1 - 2 meters per pixel. We also converted the HiRISE stereo-pair ID for each product into its proper DTM ID using the NASA Planetary Data System product naming convention for HiRISE DTMs (https://www.uahirise.org/dtm/about.php; last accessed 18.09.2019).
为深入探究火星熔岩流的表面粗糙度特性,我们借助ISIS3与ASP软件生成了30余份HiRISE数字地形模型(Digital Terrain Model,DTM),并提取了相关粗糙度数据(Rodriguez Sanchez-Vahamonde与Neish,2020)。 我们已将这些DTM公开上传至本页面以供公众使用。 HiRISE立体影像的空间采样分辨率通常为25至50厘米,由此生成的DTM单像素分辨率可达1至2米。 我们还依据美国国家航空航天局(National Aeronautics and Space Administration,NASA)行星数据系统(Planetary Data System,PDS)针对HiRISE DTM的产品命名规范,将每份产品对应的HiRISE立体像对ID转换为标准DTM ID(访问链接:https://www.uahirise.org/dtm/about.php;最后访问时间:2019年9月18日)。
