Found her!
Thanks for this challenge. Great way to inspect this incredible terrain. (Or should that Arerrain?) |

So it turns out that this area is Domoni crater and the nice folk at PIRL let me know that HiRISE had full coverage so I was able to extend the scene in 3D to provide the following images...

Layers.... These are great Sean, have subscribed to email alerts this sub-forum so I dont miss any Fingers crossed there is enough data that will enable you to create a few of Gale crater. If I could be permitted to throw an idea your way, maybe one of the entire path from landing from an elevated camera position, with tags on the ground for the rovers position every 50 sols or so? (just thinking out loud) Probably a big ask |

Amazing how much detail there is in all of these DTMs that Sean is bringing to life. I'm curious about what the brighter material is near some of the higher terrain. Nice to see an atmosphere showing up in the background. I wonder if future plans might also consider the effects of the atmosphere between the observer and the terrain?

Its on the list Steve. Although given the limited coverage of the area I wonder how much atmos to add.

Interesting question Sean. For a ballpark answer I would suggest that we can estimate an overall optical depth tau (~0.5) and dust scale height of 11km. This means the extinction coefficient at elevations near the ground would be 0.5/11km or 4.55 * 10^-5 m^-1 (tapering off exponentially as we go upward). From this both the inscatter and outscatter can be determined in the path between the observer and point on the terrain.
The impact might be subtle in the foreground, though becoming more noticeable for distant features in the background when looking near the sun. -------------------- Steve [ my home page and planetary maps page ]

Thanks for your response Steve. Horizon haze is on the to do list as a priority.
