Some info about ENC and i(nland)ENC:

basics

• "IHO S-57 format is a vector interchange format used for maritime charts. The only currently common profile is known as ENC (Electronic Nautical Chart). The format is promulgated by the IHO (International Hydrographic Organization)." [1]
• iENC extend the standard S-57 objects/attribute-set by features starting with Code>= 17000. As further distinction, these feature's and attribute's acronyms are written in lowercase letters.

viewing

• seeMyENC
• openCPN

extracting data

• ogr command line tool
• for convenience, FWTools suite and OSGeo4W contain the ogr-tools
• to extract iENC features, replace the original ogr-translation-tables with an (iENC)extended version like openCPN source:
  • s57attributes.csv
  • s57expectedinput.csv
  • s57objectclasses.csv
• some ogr2ogr formats support georeferencing, some do not

Ogr2osm

• on WIN32, install OSGeo4W (make sure, python-gdal bindings are installed)
• update the above mentioned .csv-files
• download ogr2osm.py and SimpleXMLWriter.py

• place both .py-files (ogr2osm.py and SimpleXMLWriter.py), 'test.000'-iENC-file and ienc_bridge.py-translation-file in your OSGeo4W working-directory
• start OSGeo4W shell
• command:

python ogr2osm.py -o test.osm -t ienc_bridge.py test.000

• works on NL-iENC files
• on DE-iENCs, there are decoding errors:

Line 998 in ogr2osm.py workaround:
decode(options.encoding) > decode(options.encoding, 'ignore')
