IENC manual insertion
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.
The source data download link is https://www.elwis.de/Service/Inland-ENC-der-WSV/index.html
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
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 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.
Uploading after manual correction is done with its own user IENC-Import.
Change Set comments will contain the names of the original IENC file
The data are available for the following subsections waters in Germany:
Untere Havel-Wasserstraße (Spandau - Plaue)
Wesel-Datteln-Kanal Weser Westoder
Data, tags and procedure have been tested on the Main.
The following types of objects (seamark: type =) will be inserted:
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.
