Who is driving this project? Who is Nospam2005? All the channels have gone very quiet - this forum, the OpenSeaMap forum, the import list & my original correspondent (Adrien G).
The new S-101 standard (which will eventually replace S-57) has defined a new object for Virtual AtoNs. Up till now, I had defined radio station category tags to encode these objects. Now that there is formally defined scheme for them, I have created a new object type together with its attributes. See: https://wiki.openstreetmap.org/wiki/Sea … tual_AtoNs
I have implemented this change in the renderer & the INT-1 JOSM preset. I have also updated the objects in the database to use these new tags.
Europe, 0.125 minute grid:
Bernhard,
a) Yes. The renderer places the symbol at the centroid of the area. Many lighthouses have been mapped this way - when the actual building outline was mapped, the mapper often transfered the tags from the original node to the (closed) way or multiploygon.
b) Yes. Sectored lights must have a subscript, even there is only one sector. Very often a single sector is inferred by partial obscuring of an otherwise all-round light. Please do not do this as it makes for a very untidy map. Instead tag it as "seamark:light:visibility=part_obscured" + "seamark:light:information=*" with the details of the visible or obscured arc(s). In other words, only use sectors where there is a navigational intent for the sector arc & not some artifact of the light's siting.
Regards,
Malcolm
The shade of blue I chose is close to the shallow water blue. My intention is to use the GEBCO depth data to generate lighter blues for deeper water. I am thinking of using a light blue (like the shade that you have demonstrated) in the 20-50m range & >50m use white.
I expect to launch my new seamark layer tile renderer very soon. Until then, please nominate test areas that I can do preliminary tests upon. These should contain seamarks of many different types, so that as many of renderer's features are tested as possible.
Fixed!
The following was posted to the OSM talk list:
"The SotM accommodation deal is a really good one but we do have a limited number of rooms so I encourage you to book up early. As noted the ticket sale will follow shortly and will be a similar price to Birmingham 2013.

We work hard to keep the cost as low as possible and the main way we do this is through sponsorship. If you or someone else is interested in sponsoring SotM 2016 please contact the team on sponsors@stateofthemap.org"
I have made my booking & will be arriving in the afternoon of 22 Sep & leaving on the morning of 26 Sep. Hope to see some of you there!
I have just published a beta version of the new renderer in its JOSM Imagery Layer plugin form. Please try it out and report any problems, either by opening a ticket here: https://github.com/OpenNauticalChart/S- … ite/issues or a post to this thread. Please provide an OSM file that will cause the problem. If JOSM reports an unexpected exception, please also provide the console output.
To install the plugin, refresh your plugin list and look for "SeaChart" and install it. It is invoked by selecting "SeaChart" in the imagery menu.
The renderer is about 90% complete. Yet to be added are the Brazilian notice marks. You may see some erroneous artefacts in the land area rendering - this is a known problem that I will defer until all the seamark layer rendering is complete.
Does anybody know anything about this organisation?: http://www.myshiptracking.com/ . Its website is very opaque - there is no "About" page, nor any community resources or links.
I have rendered Z6-8 globally, Z9-11 Europe & have started Z12-18 Eire/Britain. All three directories are fully populated, mostly with blank tiles. I have deleted the original set of tiles (directories 0-511).
OK, given this experience, I could instead generate a set of tiles of zoom-12 size. This would reduce the tile size to ~100kB, but not take up much more space on the server. For lower zooms, I could make a set of sea-, river-, lakes- and land-only tiles at zoom-9 size (these would be much smaller as most of the content of the full-feature tiles is roads, railways, man-mades & landuse). I could also do a set of land- & sea-only tiles at zoom-6 size.
No problems with Firefox here.
Is the slow loading a limitation of your upstream bandwidth?
OpenSeaMap is ruled by a "King", who will not engage with developers. That's why we (not half but most) left. We wanted both the "F" and the "O"!
I will attend SOTM in Brussels.
I have started rendering the SVGZ tiles & uploading to the OSeaM tile server. You can find them at: http://tiles.openseamap.org/int1base/<x>/<y>.svgz where x & y are zoom-9 tile numbers. As each tile covers a zoom-9 area, to display at other zooms they will need to be scaled by a factor of 2^(z-9).
Both Olaf & Axel have said that they will work on a base layer using these tiles.
Happy New Year to all!
Welcome, Martin.
I would like to know more about your ideas on WMS, what data is available & how we might use this.
You can look at Gabi's solution at http://openseamap.he1ix.org/map.html
Nice styling of the control buttons.
and Dirks solution at http://maps.grade.de/ol3.html
Good presentation of background maps - they are not as intrusive as the raw OSM map
Object query gives raw tag values - a non-expert plain language mode would be good.
Neither have a lat/lon grid or an edit button - the most important one for mappers!
I do not know about his change-set routines ...
The shell scripts are also in the renderer repository: https://github.com/OpenSeaMap/renderer/tree/master/work
Shawn, you probably need to raise this issue with FluxBB
So long as tiles.openseamap.org continues to be a free tile server, I will continue to upload tiles to it. Only if we get shut out, would we need to run our own tile server.
I believe that Olaf was only referring to his Online Map re-write, rather than the entire ONC project. Unlike OSeaM, all developers registered on the ONC Github are co-owners and can therefore create new projects, submit pull requests and open issues on all projects or become a team member of a project.
It would be great if we could put builds of the various contenders on one of our servers so that others could look at the end results. Then us non-webbies could view them with our browsers.
