HyMars: Mars Hyperspectral Image Classification Benchmark Datasets

We proposed three datasets for Mars exploration, including scenes from Holden Crater (HC), Nili Fossae (NF), and Utopia Planitia (UP). The data was obtained from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) aboard the Mars Reconnaissance Orbiter (MRO). Specifically, the HC is notable for its fluviolacustrine geological evolution, although the specifics of this evolution, such as water level changes and timing, remain unclear. The HC dataset consists of 418×595 pixels and retains 440 bands after filtering out water absorption and noise spectra. NF is unique for containing additional mineral phases like carbonates and serpentine, which suggests possible hydrothermal activity—an important factor for the potential emergence of biological activity on Mars. The NF dataset has dimensions of 478×593 pixels and includes 425 bands after discarding several noisy channel. UP, the landing site for the Tianwen-1 rover 'Zhurong', has a dataset size of 478×595×432.

本研究提出了三套用于火星探测的数据集，涵盖霍尔登撞击坑（Holden Crater, HC）、尼利槽沟（Nili Fossae, NF）以及乌托邦平原（Utopia Planitia, UP）的观测场景。所有数据均由搭载于火星勘测轨道飞行器（Mars Reconnaissance Orbiter, MRO）的火星紧凑型侦察成像光谱仪（Compact Reconnaissance Imaging Spectrometer for Mars, CRISM）获取。具体而言，霍尔登撞击坑以其河流湖泊相的地质演化历史而闻名，尽管该演化过程的细节（如水位变化与演化时序）仍未明确。霍尔登撞击坑数据集的分辨率为418×595像素，经滤除水体吸收谱与噪声光谱后，保留了440个光谱波段。尼利槽沟数据集的独有之处在于其含有碳酸盐、蛇纹石等特殊矿物相，这暗示了火星上曾存在热液活动——而热液活动是火星潜在生物活动出现的关键影响因素。尼利槽沟数据集的分辨率为478×593像素，经剔除若干噪声波段后，共包含425个光谱波段。乌托邦平原是中国天问一号着陆巡视器“祝融号”的着陆点，其对应数据集的尺寸为478×595×432。
