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

I don't know if this is well known or not, but I am a bit surprised to not see this discussed here. The highest point on the Kaguya data, and therefore their idea of "Mt Everest" is on the wall of a crater, which itself is on the wall of a 500km unnamed crater just north of crater Korolev on the far side
alt: 10715 image x,y: 342 1526 (from bottom right of image) lon,lat: 158.625W 5.375N The lowest point ("Challenger Deep") is on the floor of 140km diameter Antoniadi crater, also on the far side in the South Polar basin. alt: -9138 image x,y: 120 314 lon,lat: 172.5W 70.375S Both of these points are unique, in that there are no other points with the same elevation in the data. This map has all the craters I could find a list for, the highest point marked in black in the red area near the top, and the lowest point is marked in red in the deep purple area near the bottom. If the crater has a name, it's not in my list and I would love to know it. Edit: Emily already mentioned this in the middle of her blog entry, so no discoveries here. I didn't find any of this until I looked up "Antoniadi" on Google. That "unnamed" crater apparently is provisionally named Dirichlet-Jackson. |

If the crater has a name, it's not in my list and I would love to know it. Kwan, The definitive source of lunar names is the IAU Planetary Gazetteer, the most useful version of which, for the present purpose, is Jennifer Blue's Digital Nomenclature Atlas. The high point you located is on the rim of a 43-km diameter crater called Engel'gardt in LAC 69 -- actually on the shared rim of Engel'gardt and the larger ("136 km") Engel'gardt B. You can see a grayscale version of the Kaguya global DEM for this area, with all the current IAU names superimposed using a software called LTVT, here. The misregistration of some of the features relative to where they appear in the Kaguya data is due to inaccuracies in the IAU data, which were originally intended only to be accurate enough to unambiguously identify what feature was meant by each name. I understand the IAU coordinates and diameters may be redone next year using newer and better controlled images. -- Jim |
