Dataset for "Stratigraphic Evidence for Early Martian Explosive Volcanism in Arabia Terra"

Seven Digital Elevation Models (DEMs) in the Arabia Terra region, Mars, were created using spatially overlapping images (i.e., "stereo images") from the Context Camera (CTX) aboard the Mars Reconnaissance Orbiter (MRO). Each DEM location was selected to spatially overlap hyperspectral data acquired by the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) also aboard MRO. Elevation data from these DEMs were used to identify and measure geologic units that preserve minerals indicative of altered volcanic deposits. Stereophotogrammetry was performed using the Ames Stereo Pipeline toolkit v 2.6.0 and USGS ISIS Version 3.4.12.6662. Each DEM was aligned to the martian aeroid with Mars Orbiter Laser Altimeter Precision Experiment Data Records within the spatial footprint of the CTX DEM. DEM files are in the GeoTIFF raster format. Each raster has a sinusoidal projection coordinate system with a central longitude corresponding to the individual raster's center. For each CTX DEM, an ortho-rectified image was also produced. For naming conventions, references, and descriptions of each DEM site, see the enclosed readme.
