Version 3 of the HRSC map-projected dataset (REFDR3) is being superseded by a version 4 dataset (REFDR4). The new version is based on version 4 of the radiometrically calibrated images (RDRV4). The revision details are described in chapter 2.4 of the HRSC EAICD in the document directory of each volume. In addition, the JPEG 2000 images in the version 3 dataset have been replaced by GeoTIFF versions that are located in the EXTRAS subdirectory.

The version 4 dataset is being divided into multiple volumes based on mission phase as has been done for the radiometrically calibrated dataset. The new data products will be released from the most recent mission phase (extended mission eight) and going backward in time to the beginning of the mission. The version 3 map projected dataset will be transferred to the NSSDCA deep archive for permanent backup storage and taken offline at the Geosciences Node about 6 months after the complete set of version 4 volumes is available.

 

HRSC REFDR4 products have the following file names:

Hnnnn_mmm_dd4.IMG (with attached PDS label) in the DATA directory

Hnnnn_mmm_dd4.TIF (with detached PDS label) in the EXTRAS directory

where:

nnnn = 4-digit orbit number

mmm = number of the image in this orbit

dd = sensor name, can be ND (nadir), S1(stereo 1), S2 (stereo 2), P1 (panchromatic 1), P2 (panchromatic 2), BL (blue), GR (green), IR (near IR), RE(red), SR(super resolution)

4 = indicates the CODMAC level of processing which is archived in PSA/PDS (refer to Section 2.2.1 in the HRSC EAICD located in the document directory of each volume).

In ODE, REFDR4 products have the following Product IDs:

HNNNN_MMM_DD4.IMG

HNNNN_MMM_DD4.TIF
