This well - carry on volcanic crater on Mars features evidence of mass wasting — reoccurring incline linea formation . stuff is being gnaw from the gamey - elevation crater brim , form wobble gullies into the basin below .
Two photographs from HiRISE on the Mars Reconnaissance Orbiter are blended together to bring forth this high - resolution digital terrain modeling ( DTM ) . The rainbow colouring indicate elevation , with high dark-brown and red peaks run into sullen blue and purple valleys . The plain stitch outside the crater rampart are rougher , with far more small impingement craters bespeckle the lands .
The well - preserved crater is situate at -37.0 ° , 192.0 ° on Mars . The terrain model is made from highly high - resolution stereophony pairs , resulting in a mapping that so eminent settlement that each pixel represent one meter on the ground , with ground elevation differences measured in the tens of centimeters .
Building a digital aggrandisement model is a metre - consuming process , both computationally and in condition of human interposition . The introductory stride are to get up the images for input ( or “ consumption ” ) into the stereo software , triangulate the images , generating the DTM , edit any artifacts or anomalies , and finally orthorectifying the images to remove any optical distortions from tilt or view .
