CTX Orthoimage of Candidate Mars 2020 Landing Site McLaughlin Center
This product represents an orthorectified CTX image within part of a candidate landing site for the Mars2020 mission. The CTX image from which this product was derived is one member of a stereopair. Together, the images in the stereopair were used to construct a digital terrain model (DTM). The original images in the stereopair were then orthorectified using the DTM.
This orthorectified image 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 and the other orthorectified member of the corresponding stereopair are available under the "Related Products" section on the right of this page.

- Process Description
The CTX image from which this product was derived is one member of a stereopair. The members of the stereopair were first radiometrically calibrated using the USGS ISIS3 software. The calibrated images were then stretched to enhance the clarity of features in the scene and then resampled to 8 bits per pixel. These pre-processed images were then used to construct a digital terrain model (DTM) using the stereo photogrammetry software SOCET SET® (BAE Systems). The original stretched and resampled images were then orthorectified using the DTM.
See Fergason et al. (2016) for a detailed processing description.
