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.

Hi Malcolm,

some remarks:
- add some documentation eg
-- https://wiki.opennauticalchart.org/inde … Java_Suite
-- https://github.com/KastB/josm-plugins/b … /Readme.md
- buildings are not rendered

Have a nice day, Dirk

(good) News from Duesseldorf: In case there is unbooked space at end of November, the fair is willing to provide an open-source-booth for free!

This boat show is rather long lasting, we need staff for 9 days! Who likes to participate?

Hope to see you next January, Dirk

Mapzen added some recreational features to their vector tile service: https://mapzen.com/blog/v0.10-tiles/

Just requested boating related layers:
- https://github.com/mapzen/vector-datasource/issues/822
- https://github.com/mapzen/vector-datasource/issues/823

Have a nice day, Dirk

finally some time to do first testing:

+ it works!
- multi polygons need to be downloaded fully (land/ water areas) to render a meaningful map
- need to delete layer / select imagery > SeaChart again after downloading area outside previous bounds
- slider layer opacity changes just brightness, not opacity

(take a look at the sourcecode view-source:http://maps.grade.de/ol3.html for details)

Hope this helps, Dirk

Is the slow loading a limitation of your upstream bandwidth?

- http://tiles.openseamap.org/ serves the tiles
- .svgz tilesize is ~7 MB

#14 Re: general discussion » INT-1 Base Map » 2016-01-25 12:24:15

to evaluate Malcolm's tiles

please note:
- tiles load slowly
- thus display is intentionally reduced to 512x512 pixel
- chrome works best, firefox might quit

Anyone at http://www.boot.de ?

- Werner http://gps-32.de does not have a booth this year

Hi Oliver,

please browse through http://sourceforge.net/p/openseamap/mai … p-develop/ to get an idea, why we started this fork.

Have a nice day, Dirk

Merry Christmas,

what format are you interested in?

To get involved, see this thread:

Help converting INT-Chart bounding boxes into a computer readable format is highly appreciated!

Have a nice day, Dirk

Installing Discourse is beyond the scope of my server's management framework.
@Niko: Will you take care of this?
@all: Shall we use a seperate subdomain like discourse.opennauticalchart.org?

Thanks for the review!
- OSM base maps: I set opacity: 0.5
- rough overpass documentation: http://overpass-api.de/output_formats.html#popup
- raw tag values: I prefer seeing all the data and do not like filtered views (openCPN also shows the -even more cryptic- object attributes)
- edit button: Yes, having a JOSM link would be helpful
- grid display: In my case, map's target audience are inland navigators, no need for this feature here

#22 Re: general discussion » tile server » 2015-12-21 09:32:15

@Axel, rendering maschine:
Renderer code is here
   https://github.com/OpenSeaMap/renderer/ … /searender
Malcolm runs a OSM3S server
   http://wiki.openstreetmap.org/wiki/Over … stallation
and queries seamark objects. Daily snapshot should be here
I do not know about his change-set routines ...

#23 Re: general discussion » (No) new project? » 2015-12-20 20:35:28

First, I really appreciate having a discussion and would like to quote Malcolm:
"We [...] should not be afraid to 'wash our dirty linen in public’."
http://sourceforge.net/p/openseamap/mai … /34239881/

@Olaf: Please take my writings as suggestions. I consider a project like this as a 'do-ocracy'.

#24 Re: general discussion » tile server » 2015-12-20 13:41:10

@Axel, t1.openseamap.org:
I would love to see stistics, is there a chance to get this running?
e.g. http://munin.openstreetmap.org/openstre … index.html

serving seamark raster tiles, there is:

- Malcolms rendering maschine uploading tiles to
> t1.openseamap.org (maintained by Axel)
> proxy tiles.grade.de (my little v-server)

Will OpenSeaMap.org continue service?
Do we need an own maschine?
Best practice?
