ALOS-4
Observation Plan
PALSAR-3 Observation Plan
There are maps/kml of basic and thematic observation plans for each cycle.
Observation simulation results will be uploaded 4 times per year.
Basic Observation Scenario (BOS)
Note: The above Basic Observation Scenario will be updated as necessary according to the result of simulations and user comments. Please note that this is not a final version to be applied to operations.
The following tables show the sensor (observation) modes designated for each cycle based on the Basic Observation Scenario for ascending and descending paths, respectively (World/ Japan).
Shapefile of observation path/frame
Observation area of PALSAR-3 path/frame for each observation mode used in the BOS can be downloaded in Shapefile format.
The observation areas described in the Shapefiles may shifts slightly from the KML files of the observation simulation results due to the difference of calculation methods.
