The Japanese Earth-Observation satellite ALOS, developed by JAXA and launched on 24 January 2006, had the objective to provide the user community with data of sufficient resolution to be able to generate 1:25,000 scale maps.
The mission included optical and an active L-band SAR sensor payload whose high-resolution data may be used for environmental purposes.
On 22 April 2011, the ALOS satellite was lost due to a power anomaly and completed its operations phase.
