ALOS-3 Introduction of processing level
Standard Products of ALOS-3
We plan to provide ALOS-3 standard products of multiple processing levels. Followings describe the processing to be performed at each level.
L1B1 Data：Radiometric Correction of the data
- The radiometric calibration to L1A data and the addition of the absolute calibration factor are performed.
- The geometric information required for processing after L1B2 is added.
- The data is provided with scene unit.
L1B2 Data：Geometric Correction of the data
- L1B1 is a data product that has undergone geometric corrections and it provides Rational Polynomial Coefficient (RPC).
- Data can be provided in any specified range (with a minimum AOI purchase).
Two correction options are available, Georeferenced and Geocoded products.
L1C Data：Ortho Rectification
- Digital Elevation Model data (PRISM DSM, digital maps of the Geographical Survey Institute of Japan, and SRTM) is used for orthographic projection.
- Two correction options are available, Georeferenced and Geocoded products.
- Data can be provided in any specified range (with a minimum AOI purchase).
