The EOPortal links to the first PRISM sensor data from the recently launched ALOS satellite. From the ALOS website: "The ALOS has three remote-sensing instruments: the Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) for digital elevation mapping, the Advanced Visible and Near Infrared Radiometer type 2 (AVNIR-2) for precise land coverage observation, and the Phased Array type L-band Synthetic Aperture Radar (PALSAR) for day-and-night and all-weather land observation." I copied below Jonathan's Space Report on ALOS.
Japan's Advanced Land Observing Satellite, ALOS (Riku iki kansoku
gijutsu eisei) was launched on Jan 23 by an H2A from Tanegashima into a
697 x 697 km x 98 deg orbit and named "Daichi" (Land). Daichi carries an
L-band synthetic aperture radar, an optical 2.5-meter resolution mapping
camera, and a 10-meter resolution visible/near-infrared radiometer. JAXA
(the Japan Aerospace Exploration Agency) manages the satellite and was
apparently also the effective prime contractor, with Mitsubishi, NEC and
Toshiba as subcontractors.
The flight 8 H2A launch used a 2022 configuration with two SRB-A large strapons, 2 SSB Castor IVL smaller strapons, and a type 5S large fairing. The rocket launched southbound from Tanegashima and the second stage made a single burn to reach orbit. The H2A launch vehicle is operated and marketed by Rocket Systems Corp. (Kabushikigaisha Roketto Shisutemu) with actual launch activities carried out by JAXA (Ucyu Koukou Kenkyu Kaihatsu Kikou). Daichi is in a 697 x 700 km x 98.2 deg orbit; the second stage made a depletion burn which lowered it to a 548 x 699 km orbit.

An anonymous voxel writes "Japan's ALOS satellite with PRISM, AVNIR-2 & PALSAR sensors is now operational and accepting orders for data. More information in English from: http://www.alos-restec.jp/index_e.html". From the website: "ALOS Data products became available for purchase via RESTEC’s Online Data Service System (CROSS) on October 24, 2006. For the starter, RESTEC [Remote Sensing Technology Center of Japan] is offering Standard Products and Derivative-work Products (GeoTIFF or NITF format of Standard Product). Value Added Products, such as Ortho-rectified Image or Pan Sharpen Image, will be coming shortly." From a previous story: "The ALOS satellite will be carrying two high-resolution optical (AVNIR-2 and PRISM) and one L-band fully polarimetric SAR instruments (PALSAR)."
Japanese Mapping Satellite Fails to Provide Useful Images 1 comment

From the All Points Blog summary : "The "Daichi" satellite went up about two years ago. Japan launched it to collect data to create maps of remote parts of the country. Today, the Geographical Survey Institute said that the images were blurry and could not be used for the detailed mapping planned. But the images won't go to waste - they'll be used as background data for land use determination and the like."
