I just received the following from Shin-ichi Sobue at JAXA:
QUOTE The Japan Aerospace Exploration Agency (JAXA) released data from the lunar explorer "KAGUYA" (SELENE) (L2 products) during the nominal operation phase (from December 21, 2007 to October 31, 2008) to the public through the Internet. I wish I could post some images but I'm having a bit of trouble with the Data Archive website -- got registered OK, but my searches seem to return database errors. And I couldn't seem to find my way to Terrain Camera data. Perhaps it's because my brain is somewhat mushy from a day of football and beer But I give up for the night and give you guys the link in the hopes you can figure out how to get pretty pictures out of this website!L2 products are calibrated/validated processed data from KAGUYA science mission instruments. By using the L2 products, researchers all over the world are expected to advance the scientific analysis and applicability investigation of the Moon. "KAGUYA 3D Moon NAVI" services, which can show KAGUYA data using a three-dimension geographic information system (WebGIS) through the Internet, have also commenced. The developed software is based on NASA "World Wind" and the KAGUYA's images and data can be displayed using the 3D map projection function. It is necessary to download and install the free software. Please refer to the following homepage for details. L2 products during the extended operational phase (until June 2009) are scheduled to be released after processing and calibration/validation are finished. 【KAGUYA(SELENE) Data Archive】 http://www.soac.selene.isas.jaxa.jp/ 【KAGUYA 3D Moon NAVI】 http://wms.selene.jaxa.jp/3dmoon/index.html I've attached the whole doc that Shin-ichi sent me, which contains a little more info about the data sets in the release. --Emily

First thing I wanted was TOPO data - and managed to get through registration, data search - all worked. Got my email with an FTP link for the 400 meg data file.
Download 4kb/sec. I'll try again later - I wonder if it'll be mirrored by the PDS themselves. (100 - 150kb/sec now) |

Are they going to release the actual HD camera data?

That's copyrighted by the broadcast company that built the camera I believe - so no. The release specifically states
QUOTE The position and time of movie images (only catalog information. HDTV movies can be seen on the JAXA digital archives and YouTube site I managed to buy an import of the blu-ray disk they did and it's worth it for the 15 or so minutes that's included, but they've taken hours and hours of footage since then. The question for me is - what to do with a .sl2 file. |

I'm registered but I haven't figured it out yet - trying to get TC images or orthomaps in a given area, I search successfully but get 'no data'.
Terrain Camera data as far as I understand it comes in the LISM dataset. Phil -------------------- ... because the Solar System ain't gonna map itself.

OK, getting somewhere... if you run the 3D Moon Java app you can view datasets on a globe, and rotate it to view any region. Works great for the altimetry, GRS, magnetometer etc. Then I display TC on that - just a few spots. Tycho is one, Mare Moscoviense another. So back to the database search. Select LISM datasets, search on Tycho coordinates, then choose TC orthomap, and bingo, lots of datasets.
Presumably the database will be populated with other TC scenes later. Phil EDIT: I've ordered a TC map scene (2 degrees by 2 degrees, on N rim of TYcho, Surveyor 7 area... I'll be able to FTP it soon. We'll see what we get. Phil -------------------- ... because the Solar System ain't gonna map itself.

I'm downloading the elevation data (at least I hope it's the right file - LALT_GGT_NUM.sl2). Should be interesting...

--- still struggling with the format. My image appears to be a 8192 x 8192 pixel 32 bit image. So far nothing is opening it. Any suggestions (I mean from somebody who has successfully opened one!)
Edit: Oh poop! I didn't see this before. Should have done my homework first: About ".sl2"file format The form of the file compresses tar. Please uncompresses and use. (example) tar xvf dddd.sl2 dddd.sl2 : Acquisition file name Phil -------------------- ... because the Solar System ain't gonna map itself.

I'm glad you're slogging through this and not me!
Via Twitter it seems Mike Howard's been having some success with the topographic data. -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

Well - I managed to look at the resulting file - after a header it's lat, long, alt
I don't have anything I know of that can turn that into something usefull for me, such as a high bit png/tiff/tga etc etc. |

P.S. For the images - I haven't looked at those, but the elevation data has PDS headers, I wonder if the images do too. Maybe IMG2PNG could be adapted? I'd volunteer, but I don't do Windows, or scripting languages. (Actually I think IMG2PNG is an .exe, IIRC.)

I'm going to have to go out to dinner pretty soon, but I should be able to produce a 5760x2880 bump map PNG, normal map PNG, and binary stream of floats within the next 24 hours, assuming the data is good. Unless somebody else can do it faster.

I'd volunteer, but I don't do Windows, or scripting languages. (Actually I think IMG2PNG is an .exe, IIRC.) If these files have PDS headers followed by floating point data IMG2PNG might already be able to read them. If not, modifying it to do so is trivial for me - the most complex step is probably getting the data so I can test it ;-). Can't do it until about 20 hours from now though. I have been waiting more than 10 years (!) for a nice, global DEM of the Moon so this is something that really interests me. |
