Abstract

This product represents adirectional topographic slopes over 20 meter horizontal baselines within part of a candidate landing site for the Mars2020 mission. The slope map was derived from a CTX-based digital terrain model. This slope map was produced as part of an effort to characterize terrain within candidate landing ellipses for the Mars2020 mission and to aid entry, descent, and landing simulations for the mission. The parent DTM was constructed from a pair of CTX images using the stereo photogrammetry software SOCET SET® (BAE Systems). The DTM from which this product was derived is available under the "Related Products" section on the right of this page. Preferred Citation: R.L. Fergason, T.M. Hare, R.L. Kirk, S. Piqueux, D.M.

Process Description

See Fergason et al. (2016) for a detailed processing description. The 20 meter baseline adirectional slope raster is derived from a 20 m/pixel CTX DTM. The Python script used to generate the slope raster is available here: https://github.com/USGS-Astrogeology/GDAL scripts/blob/master/gdal_baseline_slope/gdal_baseline_slope.py
