Finding Apps

I just figured that it is not that easy to find software which uses OpenStreetMap or OpenSeaMap here in the wiki, so I just added some links for them to make them easier to discover for visitors. I hope that will ease finding a solution for visitors. --Trailblazr 20:51, 12 February 2012 (UTC)

Supported tagging?

There's no mention of which of the various proposed marine tagging schemes is the one that the overlay uses... I don't sail but have entered some lateral and cardinal buoys by interpolating from different directions. If you are to add areas that get rendered, there's some marine content near Helsinki and Porvoo. Alv 06:35, 4 August 2009 (UTC)

  • Guidance please! (eg rocks hidden at high tide, both as nodes and areas) --Hamish 13:03, 30 April 2010 (UTC)
    • I agree--there is not a link to anything about the tagging schema. Not user friendly at all! OSM contributors should be able to tag appropriately just with proper documentation, and without a special plug-in.  :( Neuhausr 16:55, 14 December 2012 (UTC)
      • I am in the process of writing a complete INT-1 tagging preset, I think there are some looking into some other specific seamark presets, the plugin is in the process of being rewritten to include more tagging, and finally, Malcolm have started to improve the documentation in this wiki --Skippern 08:57, 15 December 2012 (UTC)

Guide to Port Entry

Can this be made in some sort of searchable wiki format? It must be editable on web just as a wiki, but searchable according to possition and on free text search. (Searching for ports near S22 25 W040 00 should return Arraial do Cabo, Macae at least - searching for Europort should give the entry of Europort under Rotterdam, etc.) The port entries should at minimum include the name of port, position, contacts for pilot and port authority, and link to both seamap and streetmap of port. Information of restriction, local procedures for entry, reporting, etc should also be available. --Skippern 23:26, 21 August 2009 (UTC)

SRTM style Water Depth data

I would like somebody to set up a SRTM style water depth database, that can be used to insert isobaths (depth courves), and depths of points directly into a map, and will allow the generator of the map to decide what depths the isobaths should follow, and as well allow the software or the maps to highlight danger areas such as shoals close to port entrances. I know that some data are publically awailable (cannot reference sources), but as far as I know no data set are fully complete. If we/OpenSeaMap/other PD(or equivalent) source can host a complete dataset, similar to SRTM, than we have the freedom to do whatever we want with the data. --Skippern 10:16, 18 February 2010 (UTC)

  • The "Global Topography" dataset you seek is from Smith & Sandwell. This the same one which Google Earth and most other modern ETOPO world bathymetry is originally derived from.

Navigation --Bullstreetboy 09:02, 18 February 2010 (UTC) BSGPS does this as of 17th Feb 2010 [1].

Waterdepth --Bullstreetboy 09:02, 18 February 2010 (UTC) If your receiver (some fishfinders) sends $GPDTP/$GPMTW sentences BSGSP can do this.

Update frequency

unknown.. how often is the map data refreshed ? -- User:Rubke 21:55, 3 August 2010

Yes, and has it been updated to use the ODbL planet data after the license change? In which case OpenSeaMap#License needs updating -- Harry Wood 10:11, 6 November 2012 (UTC)

SeamarkEditor Bug TRAC

As I cannot find any bug trac or feedback to the developers of SeamarkEditor plugin for JOSM, I cannot change between IALA-A and IALA-B, which makes editing of lateral marks completely complicated, as the editor defaults to IALA-A while I am in IALA-B. If it is meant that I should manually change color, topmark, and all the other attributes, than a simpler tagging scheme would seriously help in the job. I discovered the problem using Windows7, don't know if it is OS related or code related. --Skippern 20:07, 2 September 2012 (BST)

Tides and shore depths

when will this data be available for OpenSeaMap? In the current rendering, we don't see Bathymetry lines at all, even for the ground ones available... is there some obstacle in getting those rendered properly? this seems to me like the most important part of this map! there are a bunch of resources available - some mentionned SRTM repeatedly previously, but there are also the US pilot charts which are now free to donwload.... Getting inspiration from the excellent work of the OpenCPN people could be interesting as well! --TheAnarcat (talk) 13:34, 22 September 2014 (UTC)

Crosslinking with "normal" wiki and reducing duplication

OpenSeaMap tagging (eg seamark:type=*) is almost completely isolated from the "main" wiki. Is this intentional? In many cases a single mapper may have interest in both domains but easily misses the other tagging or has to search for it.

Also, do we need all the duplication, eg Key:seamark:bridge:category which looks much like bridge:structure=* but is out of sync? RicoZ (talk) 13:27, 1 January 2015 (UTC) RicoZ (talk) 13:27, 1 January 2015 (UTC)

I have mentioned this since early in the process (not from the start) of making the data-structure. I have tried to document existing tags so that we avoid too much duplication of information in the same object, though I have not been listened to. There are also other projects that add some additional data to some OSeaM-interesting objects, making duplication even more extreme. --Skippern (talk) 19:17, 1 January 2015 (UTC)
