Very strange images from WAC camera.

That's not strange - that's what they should look like. It's a pushframe camera. Unfortunately, as for MARCI, they appear to be only releasing the raw data.
Phil Stooke
Don't forget, though, that the THEMIS visible images were also comprised of multiple framelets like that, and a bit later the properly mosaicked versions were also available.

Looks like flipping each 'band' will make it look a lot nicer. Should be easy to script up for someone who has the ability (not me!).
Phil Stooke
Until I can do a search for specific images, this won't be very useful to me. Probably won't be long...

Yeah - but after 3 years of MARCI, they've not done it, and I doubt they'll do it for this either.

LOLA. I want my LOLA. I've got rapid prototyping machines waiting to make moon models.

A bit off topic, but I was hoping someone can help-
I can't seem to get IMG2PNG to work on my computer- downloaded the latest version, and I was hoping to explore some of the LROC data release. However, the exe file gets this error "This application has failed to start because cftisio.dll was not found. Re-installing the application may fix this problem." I kept the cftisio.dll file in the same folder. Same result if I copy both the .exe and .dll files to the C drive... any suggestions? Running on an XP system.

The NASA Planetary Data System announces the first release of data from the Lunar Reconnaissance Orbiter (LRO) mission. This release includes raw and derived products for data acquired from the start of mapping on September 15, 2009, through December 14, 2009, along with data collected during the commissioning phase June 23 - September 14, 2009.

Data sets from the following experiments are included in this release:

· Cosmic Ray Telescope for Effects of Radiation (CRaTER)
· Diviner Lunar Radiometer Experiment (DLRE)
· Lyman-Alpha Mapping Project (LAMP)
· Lunar Exploration Neutron Detector (LEND)
· Lunar Orbiter Laser Altimeter (LOLA)
· Lunar Reconnaissance Orbiter Camera (LROC)
· Mini-Radio Frequency technology demonstration (Mini-RF)

LRO data are archived at the PDS Planetary Plasma Interactions (PPI), Geosciences, Imaging, and Navigation and Ancillary Information (NAIF) Nodes. The data may be accessed from these nodes' web sites and from the main PDS home page, http://pds.nasa.gov/ or http://pds.nasa.gov/subscription_service/SS-20100315.html.

PDS offers two services for searching the LRO archives:

The Planetary Image Atlas at the Imaging Node allows selection of LRO data by specific search criteria. The Image Atlas will be available shortly.
Please check the Imaging Node web site for information about its availability.
http://pds-imaging.jpl.nasa.gov/index_pdsimg_new.html.

The Lunar Orbital Data Explorer at the Geosciences Node allows searching and downloading of LRO data and other lunar orbital data sets (Clementine and Lunar Prospector). http://ode.rsl.wustl.edu/moon/.

To receive email announcements of future releases of LRO data, please use the PDS Subscription Service at http://pds.jpl.nasa.gov/tools/subscription_service/top.cfm.

The LOLA data are now also available !
In addition to the RDR and GDR products, I would like to point you to some products which were made with users like you in mind!

First, the big binary GDR files (maps) were converted to GeoJPEG2000, much easier to import in software like ArcGIS. Projection information is included in the headers, so that should work transparently.
location: http://imbrium.mit.edu/DATA/LOLA_GDR/

Second, we are releasing ready-made textures for Celestia. Many of you know Celestia (shatters.net/celestia), and some of you produced normal maps from the Kaguya altimetry data. In addition to a LOLA normal map, a texture showing the topography in false-color was made.
location: http://imbrium.mit.edu/EXTRAS/CELESTIA/

Enjoy !

Erwan,

Thanks for that news about the LOLA data. However, I'm a right-brained artist working on a Mac with an app like MacDEM, which was able to work with the MGS MOLA .img files *very* nicely, given the numbers of rows and columns. I suspect that I won't be able to use anything like ArcGIS. Any ideas on how I might be able to get 16-bit grayscale maps out of the files you cited? In the meantime, I'll forward the URL to my rapid prototype folks; perhaps they'll know what to do for the models. I'd really love to be able to put the grayscale maps into Terragen.

Rick

EDIT: Holy cow, I just downloaded one of the "smaller" 17MB JPEG2000 files, and it's already in 16-bit B&W. I see files in there that are 3+ GB. Yeeeoooowww. Many, many, many thanks! - Rick
Phil Stooke
Just a taste of the bounty to come:

Tracks of Lunokhod 2. I can tell at once that the old route map will need a total revision. This is only the browse image! To find it I downloaded CUMINDEX.CAT, a cumulative index file, comma delimited text file. In Excel I deleted all the columns I'm not interested in, sorted by longitude, and found the latitude i wanted, then found the image in the browse folder. The image number is in my file's name.

I just kicked out a couple of Terragen pix of Copernicus; the LDEM64 in JP2000 seems to have some striping, but I've seen that in MOLA files as well and I suspect that will get cleared up in time. I'll try running the .img through MacDEM and see what happens. Exciting times; I'm already looking into an 8" to 12" physical sphere with full relief, as well as some selected regions for rapid prototyping. - Rick

Nice rendering wink.gif
Yes, orbit improvement is ongoing... Hopefully next release some of those orbital track artifacts will be gone!
Phil Stooke
The Lunokhod 2 tracks are also clearly visible pretty much all the way from the hills south of the landing area to the end of the route, but the landing area in the image I looked at is not very obvious.

I have looked at the area I have been promoting for Lunokhod 1. It seems I was wrong! But the true location has not appeared yet.

Emily wrote up a nice blog post with Phil's discovery, along with pics of Lunas 20, 23 & 24.

I had the most frustrating day imaginable today, shuffling five ongoing projects and an insomniac baby, completing nothing; one of the projects is a lengthy blog post attempting to explain to all you folks who are not Phil how to dive headfirst into PDS volumes -- I really really will try to finish that one tomorrow. Anyway, after finally getting the kids to bed after the long, frustrating day I sat down at my computer and I was like, "For God's sake, why did they have to release those images at 5 pm Pacific after a day like today!?" I was darned if I was going to be the last space blogger to write about the Lunas and Lunokhod, which is what would have happened if I hadn't sat down to write tonight! Phil, I hope it was OK to fold in to the blog post what I know is a preliminary browse view from something I know you are working very hard on doing in much better quality.

Okay, here's a shot of the highlands. I grabbed some part of a 45 degree north file and rendered away; I'll get better at describing exact features later on. I've looked through the LOLA files over at imbrium.mit.edu, and now see how they're organized, I think.

They offer the whole moon unwrapped as a cylindrical map at 4, 16, and 64 pixels per degree, in JPEG2000, .IMG, .GRD formats. Personally, I have no idea how to use the .GRD, so I'm sticking to the JPEG2000 and .IMG files.

They have:
45 degrees north and south at (I believe) 100 meters/pixel, 200m/px, 400m/px in the same formats.
60 degrees north and south at 120m/px, 240m/px
75 degrees north and south at 30m/px, 60m/px, 120m/px
80 degrees north and south at 20m/px, 40m/px, 80m/px
85 degrees north and south at 10m/px, 20m/px, 40m/px
87.5 degrees north and south at 5m/px, 10m/px, 20m/px

5 meters per pixel must be pretty darned detailed, and the file size gets huge, like 3.4GB for the .GRD file. The 45N file that I opened seems to have the craters looking correctly circular; I'll try opening a higher latitude file to see if they correct the geometry all the way up.

I'm going to assume that with more orbits and more laser points recorded, the density of detail will just keep going up, as will the file size.

I need a new computer.

Nuts...
finally got IMG2PNG to work, and had thought this would be the calibrated NAC data... unfortunately it doesn't appear to be :-(
volcanopele
Most data submitted to the PDS for most missions will be uncalibrated, raw data. The best way to ingest LROC data, get them calibrated, reproject them, etc., is to use ISIS3. http://isis.astrogeology.usgs.gov/Applicat...issance_Orbiter lists the LROC specific programs in ISIS3, so it looks like the LROC folks use ISIS3 extensively like the HiRISE people do. If someone can post the links to the specific Luna mission images, I might be able to give them a try tomorrow, but I am not as familiar with ISIS3 as I am with ISIS2, which I use for Cassini ISS images (though I did use ISIS3 for MESSENGER).
S_Walker
Thanks Pele!
Phil Stooke
PDS has now implemented the Planetary Image Atlas search for LRO data, especially images. Go to the geometry tab, enter min and max lat and long (negative lat for south, longitudes measured to the east), and it will find LROC images for you. Best for browsing purposes, you can display and save a jpeg browse image.

Correct. Polar maps are in stereographic projection (true scale at the pole, R=1737.4km).

The GRD are netcdf-binaries, created with the GMT package (gmt.soest.hawaii.edu). They are double-precision, unlike the IMG and JP2 which are downconverted to 16bit. GMT can convert those to binary 3-column (with grd2xyz), but any netcdf-reader will do.

With more orbits, the gaps between tracks will be reduced (density of detail), but the file sizes should not change.
If your computer can handle those, it will be fine with the future releases wink.gif

Rick Sternbach
Erwan,

I haven't a clue what netcdf-binaries are, so I'll stick to the .img and JP2 files. However, I have a question about the files other than the complete cylindrical maps. I downloaded one of the 45S JP2 files, and all I see is a single 7200x7200 pixel image. Is there more of 45S somewhere, or can I not see the rest of that latitude because Photoshop isn't made to do that? Or has the rest of that latitude not been released yet?

EDIT: Okay, I see what's going on; the north and south files are closer and more detailed views centered on the poles, so this isn't like the MOLA files going around in longitude for each latitude increment. This means I'm going to have to wait for 128 or 256 or higher pixels/degree for a feature like Copernicus. Hmmm.

netcdf : http://www.unidata.ucar.edu/software/netcdf/ ; libraries allow such files to be used in various programs/platforms

this is a stereographic projection, so the sphere was projected onto a plane. This particular grid you mention extends to +/- 1440km in both directions. The projection of a point at 45degS from the south pole is ~1440km away from the pole, hence the name. Such points are at the center of each side. However, when you are at a corner of the grid, at a distance of 1440*sqrt(2)~2037km, you are actually at 29.25degS. The 45deg latitude circle would be a circle that is nearly tangent to the top-center, right-center, bottom-center and left-center point.
(it's like http://www.colorado.edu/geography/gcraft/n.../mapproj_f.html, but we're putting out a square grid instead of a disc).

Erwan,

Okay, I get it now, as I attempted to convey in my edited comment. smile.gif I'll still assume we have to wait for much higher-rez data on Copernicus. - Rick

This is a great data release. The work that's been done to make the LOLA data accessible is much appreciated. What's even more exciting is that the data set should keep getting better. It's already better than I was expecting for this first release.

Below is a view from a possible future version of Moon Globe, after just a couple hours monkeying around.

I have one technical question for Erwan: Is the data in LDEM_64.IMG signed? From the header file LDEM_64.LBL.txt I would expect it to be a signed integer offset from 1,737,400m with a scaling factor of 0.5; however, the data appears to be unsigned integer, not signed. It makes me wonder about the noted offset and scaling factor.

Thanks!

actually, thanks for finding that out (and reading the doc first wink.gif ). The cylindrical IMGs had a problem. They should now be fine (signed int16), so please redownload... Alternatively, you could download the smaller JP2 and decompress it to a raw binary file. For example, with "kdu_expand" by Kakadu Software (http://www.kakadusoftware.com/index.php).

Thanks for fixing it. It looks right to me now.

With that fixed, here's a direct comparison between a Moon Globe using the available LALT data, and the same view using the new LOLA data. The LOLA-based view wins. I'm really surprised that the LOLA data is this sharp this early.
elakdawalla
OK folks, I am stumped. I have downloaded a couple of LROC images but cannot manage to open and work with them. Photoshop CS3 chokes on them when I attempt to open as raw using the width and height specified in the header. IMG2PNG refuses to convert them to PNG format. NasaView can open the image but converts down to 8 bit mode as it does so, and the contrast is so low that all of the pixels are in like 7 of the DNs. I tried GIMP (I have the PDS import filter installed) but it just hangs. What else can I try on a Windows machine? Help!!
djellison
Emailing someone with ISIS is probably your best bet.

Alternatively, try ImageJ and importing a raw into that.

I'm not terribly savvy about all of the data products that are coming, but are we going to see a full cylindrical "texture map" type of image, a la what we saw with Clementine? A giant WAC mosaic of some kind? - Rick

LDEM_4.LBL
LDEM_4.IMG
LDEM_16.LBL
LDEM_16.IMG
LDEM_64.LBL
LDEM_64.IMG

all of the lbl's are F-'ed up ( this is NOT an exaggeration)

the headers state 3 different bit formats and as 16 bit
the IMG files ARE 32 bit
however ther really are 16 bit images saved as 32 bit ???
also the "SCALING_FACTOR" and "OFFSET" are off
yes this is messed up
this is the LBL for the LDEM_64.IMG
that i just made , and WORKS
this opens it as a 16 bit image

With such a short time between the spacecraft's arrival and the release of all these data, I'm not surprised that there are issues with metadata. There should be contact information for each data set, or, failing that, there is certainly a contact listed for the PDS Node(s) hosting each data set. If you notify them (politely) of issues, being specific about both problem and solution, I am sure you will get a response, and you'll help everyone out.
