Mars Bedding Scale Correlation Data for Western Arabia Terra

Andrew M. Annex of Johns Hopkins University provides source data for a study on bedding scale correlation on Mars. The repository includes HiRISE Digital Elevation Models (DEMs), map-projected imagery, 3D topography files, geological model outputs, and a Geopackage file with mapped layers and metadata. Data products are in formats like GeoTIFF, .ply, .vtk, and .gpkg, readable by GIS and 3D visualization software.

Use Cases

• Analyzing Martian stratigraphy and bedding thickness based on the Geopackage file containing dip-corrected bed thickness and 3D linestrings.
• Creating 3D visualizations of Martian topography using the provided .ply triangular mesh files and .vtk model outputs.
• Conducting geospatial analysis of the western Arabia Terra region using the HiRISE DEMs and map-projected imagery in GeoTIFF format.
• Validating geological models of sedimentary layers on Mars using the interpolated bedding surfaces and geologic map GeoTIFFs.

Strengths

• Includes multiple complementary data product types: DEMs, imagery, 3D meshes, and geological model outputs.
• Data is provided in standard, interoperable formats like GeoTIFF, .gpkg, .ply, and .vtk for use with common open-source tools.
• The Geopackage file contains specific metadata columns such as uuid, stratum_order, and dip corrected bed thickness.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment for large-scale processing.
• Column-level documentation for the main data file is absent; field semantics for some columns must be inferred after download.
• Last update date is unknown; freshness unverified.
