Trying conver s57 files to shape. First added enviroment variable:

OGR_S57_OPTIONS
with value
RETURN_PRIMITIVES=ON,RETURN_LINKAGES=ON,LNAM_REFS=ON

Then run:

ogr2ogr -overwrite  -skipfailures "US1GC09M_1.shp" -nlt point "US1GC09M.000"  wrecks

But have got multiple errors:

Warning 1: The output driver does not natively support StringList type for field LNAM_REFS. Misconversion can happen. -mapFieldType can be used to control field type conversion.
ERROR 6: Can't create fields of type StringList on shapefile layers.

ANy advice? I forgot to do something?

    You cannot save attributes that contain a list of values into shapefile format. You can have a try with ogr2ogr option -splitlistfields and split such attributes into many regular string fields.

  • The s57 driver gdal.org/drivers/vector/s57.html has also an option LIST_AS_STRING=ON.

  • @user30184 -splitlistfields option quiet helps. I mean errors gone, but ofc the option creates more fields in output file than in input file.

  • @user30184 I tryed LIST_AS_STRING=ON but a still got same errors when i ran ogr2ogr without -splitlistfields. So i even don't understand that OGR_S57_OPTIONS variable works or not. Is there any way to check it?

  • It is natural that splitfields adds fields. That is the intention of the option. S57 supports list attributes, for example COLOR=1 COLOR=4. With shapefile there are two options: add both values into one COLOR=1,4 or split the attribute COLOR_1=1 COLOR_2=4. Convert data into for example GML if you want to preserve list attributes.

I downloaded some test data from https://ienccloud.us/ienc/products/files/u37/ienc_s57/U37UM723.ZIP

Test 1 with OGR_S57_options

ogr2ogr -f "ESRI Shapefile" wrecks01.shp U37UM723.000 wrecks --config OGR_S57_OPTIONS "LIST_AS_STRING=ON"
Warning 1: The output driver does not natively support StringList type for field LNAM_REFS. Misconversion can happen. -mapFieldType can be used to control field type conversion.
ERROR 6: Can't create fields of type StringList on shapefile layers.
Warning 1: The output driver does not natively support IntegerList type for field FFPT_RIND. Misconversion can happen. -mapFieldType can be used to control field type conversion.
ERROR 6: Can't create fields of type IntegerList on shapefile layers.

Test 2 without OGR_S57_options

ogr2ogr -f "ESRI Shapefile" wrecks02.shp U37UM723.000 wrecks
Warning 1: The output driver does not natively support StringList type for field LNAM_REFS. Misconversion can happen. -mapFieldType can be used to control field type conversion.
ERROR 6: Can't create fields of type StringList on shapefile layers.
Warning 1: The output driver does not natively support IntegerList type for field FFPT_RIND. Misconversion can happen. -mapFieldType can be used to control field type conversion.
ERROR 6: Can't create fields of type IntegerList on shapefile layers.
Warning 1: The output driver does not natively support StringList type for field QUASOU. Misconversion can happen. -mapFieldType can be used to control field type conversion.
ERROR 6: Can't create fields of type StringList on shapefile layers.
Warning 1: The output driver does not natively support StringList type for field STATUS. Misconversion can happen. -mapFieldType can be used to control field type conversion.
ERROR 6: Can't create fields of type StringList on shapefile layers.
Warning 1: The output driver does not natively support StringList type for field TECSOU. Misconversion can happen. -mapFieldType can be used to control field type conversion.
ERROR 6: Can't create fields of type StringList on shapefile layers.

With LIST_AS_STRING=ON option ogr2ogr prints less warnings so obviously the variable works. I do not know why all the warnings are not removed but my test data was not best possible because it does not contain any data for the stringList/integerList attributes.
