Geological analysis of 3D Digital Outcrop Models (DOMs) for reconstruction of\nancient habitable environments is a key aspect of the upcoming ESA ExoMars 2022\nRosalind Franklin Rover and the NASA 2020 Rover Perseverance missions in\nseeking signs of past life on Mars. Geologists measure and interpret 3D DOMs,\ncreate sedimentary logs and combine them in `correlation panels' to map the\nextents of key geological horizons, and build a stratigraphic model to\nunderstand their position in the ancient landscape. Currently, the creation of\ncorrelation panels is completely manual and therefore time-consuming, and\ninflexible. With InCorr we present a visualization solution that encompasses a\n3D logging tool and an interactive data-driven correlation panel that evolves\nwith the stratigraphic analysis. For the creation of InCorr we closely\ncooperated with leading planetary geologists in the form of a design study. We\nverify our results by recreating an existing correlation analysis with InCorr\nand validate our correlation panel against a manually created illustration.\nFurther, we conducted a user-study with a wider circle of geologists. Our\nevaluation shows that InCorr efficiently supports the domain experts in\ntackling their research questions and that it has the potential to\nsignificantly impact how geologists work with digital outcrop representations\nin general.\n
