Unmanned Spaceflight.com _ LRO & LCROSS _ South Pole image from LOLA data

Posted by: Mars3D Dec 7 2010, 02:12 AM

I've downloaded most of the rdrs now so I thought I'd have a play with the data.

This is an image of the http://www.mars3d.com/SouthPole.jpg, The area shown is about 200kmx200km. I haven't tried to be accurate with the vertical scale.

Here's a http://www.mars3d.com/Lunar%20South%20Pole%20Contour%20Map(200m).jpg of the same area, the contour interval is 200m.

I'm getting severe orbit streaking when I create high resolution(~5m) gridded datasets from the RDRs. Has anyone noticed orbit streaks in the 5m resolution GDRs?

Heres a http://www.mars3d.com/SP4Shaded.jpg of the south pole, centered on 89.8S 270E. The area shown is 100kmx100km. The heighest point is 2078m the lowest is -2999 m. Orbit streaks are visible but not too bad in this image because it is using a lower resolution dataset (80m).

It will take time to remove all the streaks, which are caused by track-to-track errors in the orbit determination. They can be removed by comparing tracks that cross each other, but that will wait until later in the mission or after it. These are, after all, only interim products. (Incidentally, the low resolution Magellan altimetry at PDS is realy bad for that. A cleaned-up version was created at some point but does not seem to have been archived)

My anti-virus doesn't like that mars3d site for some reason huh.gif

Does it give any indication what the virus is?

I just went there, no alarms from NAV Pro.

I also get a Firefox "Attack Page" warning. This is on Firefox 4.0 Beta 8.

Posted by: Mars3D Jan 3 2011, 12:40 AM

Thanks for all the info guys, particularly stewjack.

I have now cleaned the infected pages, firefox and google may continue to show warnings until google does another check on the site. That could take days/weeks.

Posted by: nprev Jan 3 2011, 01:18 AM

FYI, on IE8, no prob. Using Firefox 3.6 (yes, I know) just now got the warning.

Thanks, I think firefox checks against google's list of sites with malware. So I am expecting it to continue to give warnings until google updates its list.

Thanks, I've done that and google is now showing the site as clean.


I can produce 3d relief maps pretty easily now so if anyone would like to request a map of an interesting area then please do. Bear in mind that the best quality results will be from areas near the poles.

Be sure and change your passwords and also look for nefarious user accounts on your site.

the poles "should" be much better than the mid latitude +45 to -45
Now there is the scientific removal but that will be in a few years .When there is much more data , that can be averaged better.
There is also an"Artistic " smoothing without bluing that i used for the 256 px./ deg. full map I made .
that involved using a heat flow pde that " G'mic" ( grastoration / Cimg.h ) uses .
an example
http://www.imagebam.com/image/7ba8e097975387

now that is NOT near the pole and thus needs a very BIG correction

just took a look at the south pole 10 m rdr IMG ,that is a bit striped
for the images below
1) the image on the left is a crop and ONLY had a "emboss" applied to it for viewing the 16 bit image
2) for the one on the right , the same plus some "destripping " in Gmic

Current orbits are good to 15-20m, so I am not surprised that the orbit errors show up at 5m resolution. We're working on it (for example, by developping new gravity field models), but 5m is currently not achievable. (For reference, the original requirement was 50m). Maybe after GRAIL gives us a perfect gravity field!
Also, keep in mind that each laser footprint is ~5m in diameter, so your maps will have very sparse coverage at those resolutions.
