Mastcam-Z images, an orthorectified HiRISE image, and a HiRISE digital terrain model were used to determine the route of the sol 308 dust devil on the ground.
Twenty control points of corresponding features were set in the Mastcam Z image and the HiRISE image. With some measurements and calculations, pixel coordinates in the Mastcam-Z image could be transformed into map coordinates of the HiRISE image. The length of the visible part of the dust devil's route is about 820 m. The average horizontal ground speed was about 30 km/h, and even 36 km/h on average between second 0 and 57. To verify the calculations, it would be interesting to see if the dust devil left a visible track. Edit: corrected typo km/s to km/h (thanks to Floyd) |
