Description
Shapefiles define major geological units and 335.6E, 18N clay-bearing outcrops in Oxia Planum, the landing site for the ExoMars 2022 'Rosalind Franklin' rover. An Excel file contains normalized reflectance (I/F) values for CRISM spectra from 12 hyperspectral targeted cubes of these outcrops. The data, compiled by Jérémy Brossier, supports the spectral and GIS analysis detailed in the accompanying supporting materials.
Use Cases
Map the spatial distribution of clay-bearing outcrops based on the provided shapefiles.
Analyze spectral signatures of Martian surface materials based on the normalized CRISM reflectance data.
Correlate geological units with spectral properties for site characterization.
Support GIS analysis for rover mission planning and geological interpretation.
Strengths
Includes shapefiles for geological units defined in peer-reviewed publications (Ivanov et al. 2020, Quantin-Nataf et al. 2021).
Contains spectral data from 12 targeted CRISM hyperspectral cubes.
Spectra are normalized for comparison, as stated in the description.
Limitations
Row count and dataset size are unknown, which may limit suitability assessment.
Column-level documentation is absent; field semantics must be inferred after download.
Last update date is unknown; freshness unverified.
Provenance

Collection Method
Likely derived from analysis of NASA PDS imagery and altimetry datasets and CRISM hyperspectral cubes.
Geography
Oxia Planum, Mars (coordinates: 335.6E, 18N and 337E, 16.7N).
Primary imagery and altimetry datasets are hosted separately on the NASA PDS server.
