Correction of inconsistencies/errors found in the INSPIRE TGs on OI

748 Views

Description

As discussed and justified in the thread below of the INSPIRE Thematic Clusters collaboration platform, it is necessary to make the proposed corrections to the following errors found in INSPIRE TG on Orthoimagery – Annex E “Encoding rules for TIFF and JPEG 2000 file formats”.

Proposal

Page 128:

  • Annex E “Encoding rules for TIFF and JPEG 2000 file formats” must be renumbered to Annex F, because there is a previous Annex E in the TG (“Data structure examples”).

Page 143: Errors in the transformation from offsets to sizes - in table 13 “Mapping between boxes in JP2 format and GML elements”

  • 'HEIGHT' box in JP2, maps to 'doimainSet.limits.high[1] - doimainSet.limits.low[1] + 1' in GML (was written ‘doimainSet.limits.high[1] - doimainSet.limits.low[1]’ by error).
  • 'WIDTH' box in JP2, maps to 'doimainSet.limits.high[0] - doimainSet.limits.low[0] + 1' in GML (was written ‘doimainSet.limits.high[0] - doimainSet.limits.low[0]’ by error).

Page 142: Errors in the transformation from offsets to sizes - in Table 12 "mapping between markers in JPEG2000 codestream and GML elements"

  • 'Xsiz' marker in JPEG2000 codestream, maps to 'doimainSet.limits.high[0] + 1' (was written ‘doimainSet.limits.high[0]’ by error).
  • 'Ysiz' marker in JPEG2000 codestream, maps to 'doimainSet.limits.high[1] + 1' (was written ‘doimainSet.limits.high[1]’ by error).
  • 'Ssiz' marker in JPEG2000 codestream, must have the following Value:

'x000 0000 to x0100101

Component sample bit depth = value + 1.
x=0 (unsigned values)
x=1 (signed values)
'

  • 'bpc' ('bpcc' type - bits per component) must have the following Condition/Value:

'x000 0000 to x0100101

Component sample bit depth = value + 1.
x=0 (unsigned values)
x=1 (signed values)
'

 Page 146: Clarification of the structure for providing XML within JPEG 2000

  • In the ‘XML box’ row in table 13 “Mapping between boxes in JP2 format and GML elements”, replace the text "The place to provide GML within JPEG 2000 (see OGC standard for more details)" (placed in the final column of the row) with the text "N/A" - meaning that thix box is not to be used.
  • Add the following extra row at the end of table 13 “Mapping between boxes in JP2 format and GML elements” - meaning that this box is the one to be used: 

ASOC Box | 'asoc' | "outer" association Box for XML formatted information to a JP2 file. | Optional | The place to provide GML within JPEG 2000 (see OGC standard 05-047r3 paragraph 8.2).
