The GDAL VICAR driver will be extended with the following enhancements:

  • addition of a write side to the driver, which is read-only currently
  • add support on this write side for the VICAR compression method.
  • Exposure of the whole VICAR label as metadata for edition.
  • Preservation of the VICAR label, in a similar way as for the ISIS3 driver, as described in ISIS3: preserve label accross conversions #1854

Examples expected from @thareUSGS

Implementation available in pull request in #1955 . Was tested with a few additional samples provided by @swalterfub and also against VICAR Open Source 3.0 and its gdal_vicarplugin (particularly BASIC/BASIC2 support)
