SHOM Balisage Import

Please support:

Import or integrate all nautical beacons, buoys, lights in France from the official database provided by the French Naval Hydrographic and Oceanographic Service (“SHOM”). This includes all seamarks managed by the DAM (Direction des Affaires Maritimes), so most but not all beacons.

The goal of this import/integration is to add all nautical beacons, buoys, lights for France so that they together with the existing lights in OSM will provide a more complete repository of navigational installations. The import will cover France, including remote territories.

Re: SHOM Balisage Import

I have already been working on this with user Adrien G. To this end, I have made a tool to automatically convert the BALISAGE data to OSM format. The work flow would be as follows:

1. Using JOSM with the OpenData plugin, read in the shape files for each object type.
2. SAVE-AS an OSM XML file.
3. Run my Java tool with that XML file as input.
4. Read the output from the tool to JOSM and merge into the Planet DB.

The code can be found here: https://svn.openstreetmap.org/applicati … art/jshom/

Re: SHOM Balisage Import

Some notes about the SHOM data:

Topmarks are not detailed - only their existence is indicated.

Lights are very incomplete. Apart from colour & range, no character, group or period is specified.

Likewise fog signals.

Sectored lights are specified with a separate object for each sector at the same lat/lon

Likewise, where a light is part of a buoy or beacon, it is a separate object at the same same lat/lon as the buoy/beacon.

This requires careful merging work before the Planet merge to build up each complete object. - The old SeaMap Editor plugin is very useful for this.
