ngunn, I don't think the distant horizon can be part of Iazu, it just doesn't stretch that far east. Also, it looks more 'hazy' than the rest of Iazu. Looking at Google Mars it does suggest that we should have an horizon about 10km (ish) beyond Endeavour in that direction. Doug, I'd love to have a CTX base map of the area. Not sure how much time I'll have to do any further analysis, but here are some ID's of CTX images that would cover all of Endeavour and Iazu. P13_006135_1789_XN_01S005W P15_006847_1770_XN_03S005W P17_007849_1793_XN_00S005W Stu, Rui has named everything around here hasn't he? James My personal favorite is P21_009141_1780_XI_02S005W_080708, because it was taken with a very small emission angle (and is thus nearly perfectly Nadir), and so high-frequency topography is least distorted in this image, compared to others. I'm working on a new CTX/HiRISE mosaic for my route mapping for the project, and put this CTX mosaic together some time ago (so it doesn't include much of Iazu). At least it's not so big I can't paste it here (I *think* >> edited to add, oops! It's an order of magnitude too big!). Scaled up to match the overlying HiRISE images in something like Photoshop, it's about 100GB, though! Fortunately, Arcmap and Global Mapper don't resample to match the scales. -Tim. |

I've been using most of these images on my route map version.
Here's the top left part of it --the so called "context map"-- where I have labelled all background pictures. There are three CTX images (from left to right: P01_001414_1780_XI_02S005W, P17_007849_1793_XN_00S005W, and P13_006135_1789_XN_01S005W) and basically two HiRISE images (PSP_009141_1780_RED and PSP_010341_1775_RED) plus a tiny bit of HiRISE ESP_011765_1780_RED to cover the area we're right now. Edit: Now I'm wondering that I should change the old "001414" image. It's the only one with an off-nadir pointing so it doesn't match so well with the other ones. |

Just making some new slides for my next talk (thanks for the help, James!), thought some of you might find this useful in making sense of Oppy's horizon view...
Close up of those particular hills here... http://twitpic.com/16xi9m/full Crying out for the full 3D view treatment, I'd say... -------------------- |

Bopolu on the horizon!
Amazing, since it's so far away. (about 65 km to center of the crater). -Tim. |

Where, where! Oh, that's unfair Tim.
You have privileged access to the raw images. We here will have to wait for the next exploratorium update in about two hours. |

I kinda like the noisy image better. Seems the cleaned image has lost a lot of detail.

there is always a trade off between noise and detail
gmic dose a good job and so dose a fft and some of the noise is the jpg artifacts after fft showing the jpg [attachment=21011:Screenshot_2.png] My personal pet peev is the jpg artifacts .the jpg format should be illegal |
