The Japan Aerospace EXploration Agency (JAXA) SELenological and ENgineering Explorer (SELENE) mission’s Kaguya spacecraft was launched on September 14, 2007 and science operations around the Moon started October 20, 2007. The primary mission in a circular polar orbit 100-km above the surface lasted from October 20, 2007 until October 31, 2008. An extended mission was then conducted in lower orbits (averaging 50km above the surface) from November 1, 2008 until the SELENE mission ended with Kaguya impacting the Moon on June 10, 2009. These data were collected in monoscopic observing mode. To create these analysis ready data, we have taken the JAXA Data ARchives and Transmission System (DARTS) archived data, map projected the data to equirectangular or polar stereographic (pole centered) based on the center latitude of the observation, and converted to a Cloud Optimized GeoTiff (COG) for online streaming. These data use a priori spacecraft ephemerides (for the nominal mission) and im[...]

These data use a priori spacecraft ephemerides (for the nominal mission) and improved, but not controlled spacecraft ephemerides for the extended mission. Therefore, these uncontrolled data are not guaranteed to co-register with other data sets.

These data are digital terrain models derived using the NASA Ames Stereo Pipeline (ASP) and the Kaguya stereoscopic data. Digital terrain models (DTMs) in this data set were bundle adjusted and aligned to Lunar Orbiter Laser Altimeter (LOLA) shot data. The sensor model intrinsics used for these data have been re-estimated to reduce inter-DTM horizontal and vertical errors. Data are controlled to LOLA using the ASP pc_align program. Data co-register at o[...]
The 25 m PALSAR-2 ScanSAR is normalized backscatter data of PALSAR-2 broad area observation mode with observation width of 350 km.
The SAR imagery was ortho-rectificatied and slope corrected using the ALOS World 3D - 30 m (AW3D30) Digital Surface Model.
Polarization data are stored as 16-bit digital numbers (DN).
The DN values can be converted to gamma naught values in decibel unit (dB) using the following equation:
γ0 = 10*log10(DN2) - 83.0 dB
CARD4L stands for CEOS Analysis Ready Data for Land (Level 2.2) data are ortho-rectified and radiometrically terrain-corrected.
This dataset is compatible with the Committee on Earth Observation (CEOS) Analysis Ready Data for LAND (CARD4L) standard.
JAXA has responded to the Earthquake events in Turkey and Syria by conducting emergency disaster observations and providing data as requested by the Disaster and Emergency Management Authority (AFAD), Ministry of Interior in Turkey, through Sentinel Asia and the International Disaster Charter. Additional information on the event and dataset can be found here. The 25 m PALSAR-2 ScanSAR is normalized backscatter data of PALSAR-2 broad area observation mode with observation width of 350 km. Polarization data are stored as 16-bit digital numbers (DN). The DN values can be converted to gamma naught values in decibel unit (dB) using the following equation: γ0 = 10*log10(DN2) - 83.0 dB. Included in this dataset are ALOS PALSAR Level 1.1 and 2.1 data. Level 1.1 is range and single look azimuth compressed data represented by complex I and Q channels to preserve the magnitude and phase information. Range coordinate is in slant[...]
