Unit Map and Dips/Strikes of Sakarya Vallis, Gale Crater, Mars

<p>This dataset comprises the unit map derived from 3D analysis of Sakarya Vallis in Gale crater, Mars. The units are named Package 1&ndash;7. These packages have been extrapolated from morpho-stratigraphic analysis of a HiRISE scene in PRo3D. They have been further extrapolated using underlying image data. Included here is a shapefile representing the marker bed (Milliken et al. 2010) in Gale crater. The &quot;CDD&quot; refers to the Central Debris Deposit, identified by Hughes (2021).</p> <p>The structural data represents dip measurements along the boundaries of these packages within the feature; the &quot;sub-package&quot; data represent layering within the packages. For more on how dip is calculated in PRo3D, see https://pro3d.space/.</p> <p>Finally, the profiles mark the locations where topographic profiles were extracted for constructing cross-sections, as discussed in the thesis Persaud (2022).</p> <p>These data are intended to be displayed with the HiRISE ORI (https://doi.org/10.5281/zenodo.5808371) and CTX ORI mosaic (https://doi.org/10.5281/zenodo.5808357) over Sakarya Vallis, and over the basemap over the northwest of Aeolis Mons (https://doi.org/10.5281/zenodo.5808381).</p> <p>Format: SHP, SHX, DBF, PRJ, QPJ<br> Projection: Equidistant cylindrical<br> Datum: Spheroid (r = 3396.190 km)</p> <p>N.B. the PROJ4 format of the project is &quot;+proj=eqc +lat_ts=0 +lat_0=0 +lon_0=0 +x_0=0 +y_0=0 +a=3396190 +b=3396190 +units=m +no_defs&quot;</p>
