They look great - the contrast is definitely improved. The corresponding MMB metadata update will be delayed a few days for technical reasons.

Great release Dan.

For those wondering about some dropped data on around Sol B0882, that data is unfortuantely gone for good, I asked JB about it and he's check it. Amazingly, a rare occurance, of dropped data that didn't get retransmitted before the products were deleted from flash.

What about the dropout in the Sol 809 picture from Spirit? That's gone too I suppose?
djellison
I would have thought so. The PCT website shows things that are not fully down and not yet deleted...unless it's in there, it's probably gone.

Finally got the MMB metadata updated with the calibrated color from PDS 11.

Crystal clear mosaics.

The thing I wonder about the data releases, MER or otherwise. Is there any place that DVD's can be ordered ? Maybe there are services that d/l for you and send it on DVD ? I'm not sure really, how big are the MER archives, for example ? Would it download on an 8mb connection in a few hours ?

There are so many derived data sets of different sorts of end product that the total probably runs dozens of GB's.

Most Navcam, Hazcam and Pancam frames end up with mant different treatments, in a range from 2mb to > 10MB - perhaps as much as 20MB/image from all the derived products. With 250k images - that's 5TB I think.

The basic radiometric set of pancam image at 125,000 images of 2mb each - 250 Gbytes.

Thanks Doug,

So only subsets of the data would ever be available, on one CD anyway. I suppose the PDS, or someone could produce the whole thing on about 30-35 DVD's if they're double layer DVD's. Or a harddrive but that would just be impractical unless there's some other storage medium I don't know about.

Hmmm... maybe the 2 gig I have left on my drive is not going to hold a full d/l by MMB ! I think I'll leave it for specific parts of the mission I want and wait for a DVD set wink.gif .

The PDS stopped providing stuff on physical media I think - with MGS. I've been speaking to the UK RPIF (well, Pete) about mirroring PDS stuff in the UK for faster UK access, or allowing access to it via the RPIF for burning onto Physical media.

Doug
MouseOnMars
Excellent idea.

Do you know if I can still get hold of the MGS data on CD / DVD from somewhere ?

It's probably been out there for awhile, but I just noticed that slinted has updated his callibrated color images to include sols 990-1080. Some wonderful stuff from Victoria Crater, there. Thank you, slinted.

After discovering the PDS Mer picture place, I tried to make a single color picture with the calibrated data. It was hard to convert IMG file. The IMG2PNG of Bjorn seems to don't work sad.gif. But, I finaly found a Gimp plug-in who can directly open it (http://areo.info/gimp/).

So, the image (Cabo Frio on Sol 952). I am going to re-make the pano.

It works - believe me - I've used it to convert tens of thousands of MER images. What are you doing with it?

I double-clik on it. The command windows open less than one second before closing automaticaly. I tried to slide-put the IMG file on it, then a dialog box opened who say that the file is corrupted.
djellison
Right - open notepad

put

CODE
img2png *.img -r
md img
move *.img img



in it - save it as run.bat

Put img2png.exe and run.bat into a folder with some IMG's

Double click run.bat

Done

It runs. But, is it normal that the png's are so ... darks?

You probably want to apply a scaling factor, using the -s tag. From Bjorn's page, it seems the default scaling for MER images is 8, if need double the brightness, the command would be : "img2png *.img -r -s16"
Ant103
Okay Slinted wink.gif.

It's a great pleasure to "play" with PDS images. And I've made a first "calibrated" panorama who showing Cabo Frio. Happy to see that it need no gain compensation when stitching smile.gif.

It tends to do this to me too, mostly over weekends.

Is that raw or calibrated data? The sky looks a bit noisy for a flatfielded image... unsure.gif
Ant103
Calibrated data. But, I have to say that I have sharpens the image for a bit more details. That's the reason why the sky is noisy.
