Mars Crater CTX Images with Degradation Labels

54,104 grayscale CTX image patches (1024×1024 PNG) of Mars craters, one per crater, each centred with ~1.5× crater-diameter padding, with a degradation label matching one of three degradation classes (A=fresh -> C=heavily degraded). labels.csv provides: crater_id lon (longitude) lat (latitude) diameter label source_tile All images are keyed to images/<crater_id>.png. Note: label values are random-forest predictions, not manual annotations. Treat as noisy. Sources & attribution. Crater imagery is derived from the Murray Lab Global CTX Mosaic of Mars (Dickson, Ehlmann, Kerber & Fassett 2024, Earth and Space Science, DOI:10.1029/2024EA003555; acknowledging Caltech, Malin Space Science Systems, and JPL). The label degradation classes are from Liu et al. (CC-BY-4.0; DOI:10.5281/zenodo.11514787).
