[gdal-dev] sounding point handling by OGR library

I had some questions regarding the additional feature of sounding
point handling by the OGR library.
I know that we need to turn on the options SPLIT_MULTIPOINT and
ADD_SOUNDG_DEPTH options on.
1) Is there a way to turn them individually on without affecting the
other suboptions in OGR_S57_OPTIONS ?
Because if we do it by the following statement:
Then there is a possibility to overwrite the other suboptions
PRESERVE_EMPTY_NUMBERS, LNAM_REFS, and RETURN_LINKAGES.
2) With turning ADD_SOUNDG_DEPTH option on, the points become three
dimensional, where the Z
member variable contains the retrieved depth value I guess. Here,
my question is, does this depth
retrieval process take care of any unit conversions (meters,
fathoms, feet, etc.) ?
