Minimize Products Information

ALOS PALSAR products are available via the new ESA PALSAR data On-The-Fly (OTF) processing and dissemination system.

The service currently provides access from ESA's archive to the following PALSAR FBS, FBD and PLR L1 high-resolution data products.

 

Note that there are differences between JAXA and ESA ALOS PALSAR CEOS product formats. The ESA L1.1 is in zero-Doppler and not beam coordinates. The signal data record headers also have a different format - the ESA "L1:1" products are basically identical to L1.5 products, aside from slant range projection/pixel dimensions.

JAXA Processing Level Equivalent

Fine Beam Single polarisation FBS_RAW_0P Raw data generated by every downlink segment and every band. Divided into an equivalent size to one scene. 1.0
FBS_GDH_1P Ground range Detected, Normal resolution product Was 1.5 but superseded by ESA CEOS product
FBS_GEC_1P Geocoded product Was 1.5 but superseded by ESA CEOS product
FBS_SLC_1P Slant range single look complex product Was 1.1 but superseded by ESA CEOS product
Fine Beam Double polarisation FBD_RAW_0P Raw data generated by every downlink segment and every band. Divided into an equivalent size to one scene. 1.0
FBD_GDH_1P Ground range Detected, Normal resolution product Was 1.5 but superseded by ESA CEOS product
FBD_GEC_1P Geocoded product Was 1.5 but superseded by ESA CEOS product
FBD_SLC_1P Slant range single look complex product Was 1.1 but superseded by ESA CEOS product
Polarimetry mode (4 polarisation) PLR_RAW_0P Raw data generated by every downlink segment and every band. Divided into an equivalent size to one scene. 1.0
PLR_GDH_1P Ground range Detected, Normal resolution product Was 1.5 but superseded by ESA CEOS product
PLR_GEC_1P Geocoded product Was 1.5 but superseded by ESA CEOS product
PLR_SLC_1P Slant range single look complex product Was 1.1 but superseded by ESA CEOS product

 

PALSAR WB1 (ScanSAR Burst mode 1) will also be made available at a later stage.

ALOS products follow the standard CEOS format convention. The dataset contains all ESA acquisitions over the ADEN zone (Europe, Africa and the Middle East) plus some worldwide products received from JAXA. Further information on ADEN zones can be found in this technical note.

 

Products Availability

 

The PALSAR OTF system provides direct online access to ESA's ALOS PALSAR archive for ESA registered users, without the need to interface with the ESA Order Desk.

 

Data are accessible through the ALOS PALSAR On-The-Fly web interface

 

If users do not have an EO-SSO account on Earth Online, it is possible to create an account following the registration instructions.

 

For any additional inquiries please contact eohelp@esa.int.
