Co-registered U. Arizona HiRISE DTM and ORI over Sakarya Vallis, Gale Crater, Mars

Local digital terrain model (DTM) and orthorectified image (ORI) of Sakarya Vallis, west of Aeolis Mons in Gale crater, Mars. The DTM was originally processed by the University of Arizona (DTEEC_006855_1750_007501_1750_A01, https://www.uahirise.org/dtm/dtm.php?ID=PSP_006855_1750); this product is co-registered to CTX DTMs which were themselves co-registered to HRSC DTMs (Persaud et al. 2021, https://doi.org/10.5281/zenodo.5808357) using Ames Stereo Pipeline. The ORI was processed using Ames Stereo Pipeline and adjusted with GDAL.

Image ID of the ORI: PSP_007501_1750_RED

本数据集包含火星盖尔撞击坑埃俄利斯山（Aeolis Mons）西侧萨卡里亚谷（Sakarya Vallis）的本地数字地形模型（Digital Terrain Model, DTM）与正射校正影像（Orthorectified Image, ORI）。该数字地形模型最初由亚利桑那大学处理生成（编号：DTEEC_006855_1750_007501_1750_A01，来源链接：https://www.uahirise.org/dtm/dtm.php?ID=PSP_006855_1750）；本产品已与CTX数字地形模型完成配准，而CTX数字地形模型本身已通过Ames Stereo Pipeline与HRSC数字地形模型完成配准（Persaud等，2021，https://doi.org/10.5281/zenodo.5808357）。该正射校正影像通过Ames Stereo Pipeline处理，并经GDAL进行了校正调整。
