ALOS PRISM Data Products (ALOS.ALOS.PRISM)
PRISM (Panchromatic Remote-sensing Instrument for Stereo Mapping ) scene is defined by RSP (Reference System for Planning) number (Path, Frame) and scene shift distance. Each path is separated into 7200 frames on the basis of the argument of latitude of satellite. Frame number is allocated every 5 scene (approximately 28 km). Scene shift can be carried out in the processed data, and distance of the scene shift is specified by the number of frames. In the ALOS Data Processing Subsystem, the scene of a Raw product (geometrically uncorrected) and a Geo-reference product (map-projected based on the flight direction) are defined by determining image position and image range using input data according to the RSP. And the scene of a Geo-coded product (projected based on the direction on the map) is defined by rotating the same range of the Geo-reference image to map-north.
The PRISM Processing Software performs radiometric and geometric corrections and generates Level 1A, Level 1B1, and Level 1B2 products:
ALOS products follow the standard CEOS format convention. The detailed product format specifications have been defined and are maintained by JAXA. Read more

ESA Earth Observation Campaigns Data
ESA has been involved in many Earth Observation campaigns over the past 25 years, from ground-based surveys, to ships at sea, aircraft and balloons in the atmosphere and the orbiting satellites in space.
