Kaguya TC Morning V02 Global Mosaic 474m (64ppd)
Note: Full resolution (4096ppd) version access provided further below.
This near-global mosaic was generated using data from the SELenological and Engineering Explorer (SELENE) “Kaguya” Terrain Camera (TC) instrument. TC source data originated as map-projected tiles at ~10 m/pixel spatial resolution.
The Japan Aerospace Exploration Agency (JAXA) launched the Selenological and Engineering Explorer (SELENE, also called “Kaguya”) spacecraft to the Moon in September 2007. The mission concluded June 10, 2009 when the spacecraft was intentionally crashed onto the lunar surface. Subsequent data collection and mapping efforts resulted in “the largest lunar exploration project since the Apollo program” (Haruyama, 2008). The high-performance optical Terrain Camera (TC), a 10-meter spatial resolution stereo-camera, was part of the Lunar Imager/Spectrometer (LISM) instrument suite (Kato, 2007), along with the Multi-band Imager (MI, 20 m/pixel; Ohtake et al., 2008) and Spectral Profiler (SP; Matsunaga et al., 2008).
Mission objectives for the TC included production of global, high-resolution, high-contrast mosaicked maps (tiles) of the Moon [e.g., Kato, 2006; Haruyama et al., 2008]. The SELENE team released map-projected near-global coverage of TC data with both Morning (“Morn”) and Evening (“Eve”) illuminations (low-sun, early or right-to-left low-angle solar illumination, and late or left-to-right solar illumination). The 3x3-degree tiles (7200 nominal count per set) are spatially co-registered to the Kaguya global DTM and match very well with the positions of the Apollo Lunar Retroreflector array (-17 to 5 m longitude, -20 to 48 m latitude, 3 to 5 m elevation; Haruyama et al., 2012). With the quality of registration, high spatial resolution, and image clarity, these data provide excellent complements to color data such as those from the LRO Wide Angle Camera and the Clementine UVVIS for geologic studies, mapping, and morphologic and structural analyses of the lunar surface.

One of the primary goals for the Kaguya mission was to augment the high-resolution image data available for the lunar surface, particularly the far side. At 10 m/pixel globally, the TC data effectively bridge the resolution gap between the LROC WAC (100 m/pixel) and the LROC NAC (~1 m/pixel) data and thus they provide invaluable contextual information. The data have enabled discoveries of relatively small lunar features such as lava-tube skylights, small impact craters used to determine relative age, lack of exposed ice at Shackleton crater (lunar south pole) and mare eruption ages. Availability of the global TC data will greatly facilitate a wide variety of lunar studies, including relative and absolute chronology (e.g., crater counting), geologic mapping, structural analyses, site characterization, etc. to better understand the Moon’s geologic record. The low-sun and dual-illumination TC data provide unmatched morphologic information that support geologic and feature mapping at local to regional scales (~1:50, 000 to ~1:250, 000). The availability of coverage at multiple illuminations will help to ensure that any given site can be studied.

- The TC Morning source products were released in 2010, with positional information based on lunar gravity field model and orbital parameters determined prior to January 2010. They may retain small errors (<10 pixels) in registration as well as gaps, missing pixels, and null values in the tiles. These issues appear to affect <10% of the TC data.
- Completeness Report
This TC Morning version 2 mosaic consists of 6, 371 tiles (of nominal 7200) as released by the Kaguya Team.
- Process Description
Source data were downloaded from the SELENE-Kaguya TC on-line data repository. Source product “PDS-like” image labels contained primary information with the need for specific corrections to be applied in preparation for ISIS ingestion and mosaic assembly. These corrections included target value updates, map scale value updates, map projection offset adjustment, and special pixel value assignment. Corrected products were then ingested within ISIS via the ‘kaguyatc2isis’ application. Mosaics were assembled via the ‘mapmos’ ISIS application. OS shell and Perl scripting were utilized within the entire download, processing, and mosaicking procedures. Storage and processing cluster infrastructure were utilized.
