The High Resolution Stereo Camera (HRSC) Version 3 Reduced Data Record (RDRV3) data products are standard IMAGE objects. An IMAGE object is a two-dimensional array of values, all of the same type, each of which is referred to as a sample. IMAGE objects are normally processed with special display tools to produce a visual representation of the samples by assigning brightness levels or display colors to the values. An IMAGE consists of a series of lines, each containing the same number of samples.

RDRV3 data products are processed by software which performs the following steps:

  • Remove all telemetry headers from the data

  • Sort the data by sensor and combine the image data with the housekeeping data

  • Decompression of the data

  • Radiometric calibration of the data

  • Calculation of the footprints for every image

HRSC RDRV3 products have the following file names:

Hnnnn_mmm_dd2.IMG

where:

nnnn = 4-digit orbit number

mmm = number of the image in this orbit

dd = sensor name (can be ND, S1, S2, P1, P2, BL, GR, IR, RE, SR)

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

2 = processing level

In ODE, RDRV3 products have the following Product IDs:
