Shapefiles of the geomorphological map and the crater counting for age estimation of the glacial landforms of Acheron Fossae, Mars.

These files have been produced to map glacial landforms in the Acheron Fossae region of Mars. Included here are shapefiles outlining all glacial landforms within the study site, as well as the various surface features. The shapefiles here include: LDA/LVF Deposits Concentric Crater Fills Small-scale LDAs Graben top and wall Impact craters Large Massif with GLDA Small mounds/Massifs The shapefiles are projected in the Mars 2000 coordinate system. Along with the shapefiles, we have also added the crater counting data used for the age estimation of these glacial landforms. The file includes shapefiles of craters formed within the glacial landforms and the area confined by the landforms.本数据集旨在开展火星阿谢隆槽沟区（Acheron Fossae）的冰川地貌制图工作。本次收录的内容包含研究区内所有冰川地貌及各类地表特征的轮廓形状文件（shapefile）。 本次提供的形状文件包括： LDA/LVF堆积体（LDA/LVF Deposits） 同心坑充填物（Concentric Crater Fills） 小型LDA堆积体（Small-scale LDAs） 地堑顶部与壁面（Graben top and wall） 撞击坑（Impact craters） 携带GLDA的大型地块（Large Massif with GLDA） 小型丘体/地块（Small mounds/Massifs） 所有形状文件均采用火星2000坐标系（Mars 2000 coordinate system）进行投影。 除上述形状文件外，本数据集还附带了用于估算上述冰川地貌形成年代的撞击坑计数数据。 该数据集包含形成于冰川地貌内部及地貌约束区域内的撞击坑形状文件。
