IENC manual insertion

From OpenStreetMap Wiki
Jump to: navigation, search

Manual insertion of buoys of the large German rivers into OSM from the IENC of the Water and Shipping Administration of the federal government (WSV).

The terms of usage for the IENC data of the German IENC have finally been modified to fit the needs of OpenStreetMap: Now there has no source note to be attached, especially if the data has been modified.


Data Source:

The source data download link is https://www.elwis.de/Service/Inland-ENC-der-WSV/index.html

Terms of Use:

Permission to import has been explicitly granted. The formulation of the Terms of Use has been specially adapted to the requirements of OpenStreeMap.

Procedure:

The insertion is purely manually: From the source data, the relevant data are partially extracted and opened in JOSM. Here each node and each polygon is checked manually, especially if the object is probably already available. Possible duplicate nodes are not imported or merged, landmarks are transferred the on existing buildings.

This will be no automated import. No files "will be uploaded to OSM directly:

1. The appropriate are is downloaded from OSM into JOSM

2. The IENC nodes and polygons of potential interest are opened in JOSM (in a different layer)

3. Relevant data is manually transferred into the OSM layer

4. The edits are uploaded to OSM

Conversion:

The IENC data is converted from the the S-100 to OSM format by a script called s57toosm. It is availiable at Github as s57toosm.

Inserted information:

Inserted will be elements relevant for inland navigation such as fairway buoys, navigation signs (traffic signs) and the labeling of buildings as landmarks, e.g. smokestacks. At places where the riverbanks are "raw state" (very long straight lines or rough sawtooth pattern), we adapt the shore course (waterway = riverbank) in balance with the bing satellite image.

OSM user:

Uploading after manual correction is done with its own user IENC-Import.

Change set tags:

Change Set comments will contain the names of the original IENC file

Areas:

The data are available for the following subsections waters in Germany:

Berlin-Spandauer-Schifffahrtskanal

Donau

Dortmund-Ems-Kanal

Elbe

Elbe-Havel-Kanal

Elbe-Seitenkanal

Havel-Oder-Wasserstraße

Main

Main-Donau-Kanal

Mittellandkanal

Mosel

Neckar

Rhein

Rhein-Herne-Kanal

Ruhr

Saar

Spree-Oder-Wasserstraße (Teilabschnitt)

Untere Havel-Wasserstraße (Spandau - Plaue)

Wesel-Datteln-Kanal Weser Westoder

Test:

Data, tags and procedure have been tested on the Main.

Object types:

The following types of objects (seamark: type =) will be inserted:

seamark:type=anchorage

seamark:type=anchor_berth

seamark:type=beacon_cardinal

seamark:type=beacon_isolated_danger

seamark:type=beacon_lateral

seamark:type=beacon_safe_water

seamark:type=beacon_special_purpose

seamark:type=berth

seamark:type=buoy_cardinal

seamark:type=buoy_installation

seamark:type=buoy_isolated_danger

seamark:type=buoy_lateral

seamark:type=buoy_safe_water

seamark:type=buoy_special_purpose

seamark:type=cable_submarine

seamark:type=daymark

seamark:type=fairway

seamark:type=harbour

seamark:type=landmark

seamark:type=light

seamark:type=light_major

seamark:type=light_minor

seamark:type=light_float

seamark:type=light_vessel

seamark:type=mooring

seamark:type=navigation_line

seamark:type=notice

seamark:type=restricted_area

seamark:type=signal_station_traffic

seamark:type=signal_station_warning

seamark:type=small_craft_facility

seamark:type=topmark


The supposed duplication between tags of pure objects (e.g. lighthouse manmade=lighthouse or building=church) and their meaning for navigation (e.g. seamark:type=light_major or seamark:type=landmark) has already been well discussed: Not every such objects has a significance for navigation. So it is not a redundancy, but a supplementary tagging. This applies in particular to harbor=yes/seamark:type=harbor and historic=wreck/seamark:type=wreck.
