Local digital terrain model (DTM) and orthorectified image (ORI) mosaics over Sakarya Vallis, west of Aeolis Mons in Gale crater, Mars. The two constituent DTMs were processed using the CASP-GO suite described in Tao et al. (2018); the ORIs were processed using Ames Stereo Pipeline. The DTMs were then co-registered to an HRSC DTM mosaic (Persaud et al. 2021, https://doi.org/10.5281/zenodo.5808354) and each other using Ames Stereo Pipeline, and then cropped and mosaicked.

Format: GeoTiff
Projection: Equidistant cylindrical
Datum: Spheroid (r = 3396.190 km)
Bit depth: Float32
DTM grid-spacing: 18 m/pixel
ORI resolution: 6 m/pixel

Stereo pairs (from Grindrod and Davis, 2018):

  • P04_002675_1746_XI_05S222W, B21_017786_1746_XN_05S222W
  • D02_027834_1748_XN_05S222W, G04_019698_1747_XI_05S222W

Image IDs of the ORIs: P04_002675_1746_XI_05S222W, D02_027834_1748_XN_05S222W
