[gdal-dev] extract wtwdis and unlocd with distance marks from IENC

[wulf]

Hallo again,

I found bit more info, so I thing I asked the wrong question.
what I miss/need is
   wtwdis
   on some points
   unlocd

is this possible with ogr2ogr?
Or where can I get further hints.


If I check the details from Points I like to extract in opencpn I get


or points without unlocd
  distance mark (dismar)
  52 13.7280 N, 011 40.0977 E
  CATGEO   POINT
  CATDIS   distance mark not physically installed(1)
  hunits   kilometers(3)
  wtwdis   319.9 m
  unlocd   DEQWS031010000003199


or points without unlocd

  distance mark (dismar)
  52 13.6335 N, 011 40.1771 E
  CATGEO   POINT
  CATDIS   distance mark not physically installed(1)
  hunits   kilometers
  wtwdis   310.1
