QUOTE (Daniele_bianchino_Italy @ Jul 4 2018, 08:00 AM)  It seems like exposure of sulfur after volcanic eruption, but this should be salt or sodium carbonate [wildespace]. Looks like the travertine springs in Pamukkale, Turkey.  Bigger https://upload.wikimedia.org/wikipedia/comm..._panorama_2.jpg |

My eyes are seeing something like this:
1. Bedrock (or 'bedrock') 2. Talus made up of fragmented bedrock 3. White material deposit 4. Scattered debris atop white material 5. Eroding white material |

the Max Planck Institute site also has a striking image of the rim of Occator crater:

Oh my! Those mosaics are absolutely stunning!
I see lot of pockmarks (pits/craters) on that white surface, although gray material within linear troughs/chasms and around that flat elevated mesa at SW is rather smooth. Those bright fluvial features streaming down from flat-top mesa seems to be mixing with darker stuff which then covers underlaying bright deposits. I wonder, how amazing look would it be, standing down there next to central dome and looking SW at those streams! Streams and landslides within troughs seems to be the youngest geological features here. Or those pockmarks all around the bright stuff are not impacts, but rather some sublimation-pits or even cryovolcanic calderas?? Either way, it's crazy landscape.. |

Each pixel should cover around 3-3.5 meters in these images.

Your images are enlarged more than those inserted on: https://dawn.jpl.nasa.gov/multimedia/images/ceres.html WHy? I would like to see these bigger, Like these: https://www.jpl.nasa.gov/images/dawn/20180716/PIA21924.jpg we would not have great images of Hauna mons if I understood correctly but only of crater 0ccator . . Why did not we have temperature maps for Ceres? .. . |

It is proving quite difficult to visualize topography in the Cerealia Facula mosaic. For instance, the fractures keep appearing as ridges to my eyes.
Is it yet possible to produce 3D images, or lay portions or all of the mosaic on an elevation model? |

Save the image on you computer, open in an editor and rotate 180 degrees. Light is coming from wrong angle for your brain to work--mine too--till flipped

The extreme light-dark pattern really fools the eyes. |

Here is my 3D version of Ahuna Mons.
I use JMars software to generate DTM and ortho texture (LAMO phase) and create CMOD model to Celestia. https://www.youtube.com/watch?v=EMW4bXI9-o8 -------------------- Adam Hurcewicz from Poland
