Thought I'd start a new thread for stuff done with the HRSC DEM's....

http://www.rlproject.com/HRSC/446_438/446_438_flydown_lo.mov (3.8 meg) I'll confess, this one went a bit wrong, and a long swathe of the animation ended up being 'underwater' as it were. So it cut short |

I'm just speechless. Thanks for these Doug.
I love doing this with Google Earth. Hopefully we'll have enough data some day for the entire Red Planet. -------------------- If Occam had heard my theory, things would be very different now.

Some DEM's are cool, some not so great. Cloud, ice, fog all screw them up (nothing to co-register for elevation I guess)

This one (attached - Arsinoes Chaos ) and a very long-noodle of Olympus Mons rendering now.
These things usually have an ND image of 12.5-50m/pixel, 4 colour images of 100-250m/pixel and an elevation image, usually of about the same res as the colour, perhaps slightly lower. Most of the time I drape the colour over the ND to super-res it. With the Ol. Mons one, I thought "Do I drop the colour over the higher res ND filter?" Then I discovered the ND is 17568x144800 - That's a full HiRISE image sort of filesize, and the HRSC to Tif convertor has to load the whole image into ram. So that's a no for now On the upside, I should be on 8 gig of ram by the end of the week (dropping 4 more in) I want to do Elysium Mons, but the DTM is so soft it's a bit dull really. Doug |

Fantastic animations!
How much vertical exaggeration do you have? As much as 5 to 1, I would guess. Could you try one without vertical exaggeration? |

As I've said elsewhere, the vert exag is not an exact science yet - but it's far more like 2:1 than 5:1.

http://www.rlproject.com/HRSC/500/500_around_lo.mov (7.1 meg) Trying now to do one of Holden and Eberswalde, with a CTX swathe across the Eberswalde part. Cropped myself down to a tiny tiny part of the orig HRSC image, but having to blow it up 5x to match the res of the CTX (i.e. show CTX at full res) is bringing my machine to its knees! Shh - don't tell it, I've got the RGB to drop on top next Doug |

Even though I haven't downloaded all of these yet I can say that these are awesome. I'm surprised I haven't seen more HRSC animations - this should be great for PR purposes.
If only we had some HIRISE DEMs... |

Just wanted to say how very much I appreciate these animations. I probably missed some earlier discussion but I was wondering, Doug, if vertical scale is a parameter that you can 'tweak' relatively easily, if (say) you wanted to make versions with no exaggeration?

I can change it very easily - and actually getting it right on 1x elev isn't too problematic either. I've not measured most of these accurately, but they're averaging 1.5ish - 2ish, that sort of thing.

! I was looking forward to something like this from you Doug, this stuff is very pleasing.

Yup - 3ds max, using the VRay renderer for displacement of the terrain.
Oly.Mons to be added later. It's a big noodle much like the very first one, but it's cool Doug |
