@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
http://tiles.openseamap.org/seamark/world.osm
I do not know about his change-set routines ...
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'.
@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?
sorry, I was thinking about tile serving. Shall we start a new topic at 'development > general discussion > tile server'?
Hi Axel,
how do I call the preview api?
I would expect something like http://tiles.grade.de/tiles.py/seamark/preview.html
Thanks, Dirk
Hi Shawn,
there is 'UTC +8:00 Greater China, ...'
Have a nice day, Dirk
We might start stating what each individual expects and wants to achieve.
Here comes my initial try https://wiki.opennauticalchart.org/inde … rk--#Goals
@Gabi:
- feel free to grab all the code you need
- as said, things I consider useful are (see first post in this thread)
-- rewrite URL
-- overpass.api query
-- geolocation with map orientation
- http://tiles[1-3].grade.de is my tileserver based on http://tilestache.org/
- tiles.py is the api call
- proxy tile providers:
-- openriverboatmap/{z}/{x}/{y}.png
-- NAUTHIS_SkinOfEarth/{z}/{x}/{y}.png
-- ncp_diepte14/{z}/{x}/{y}.png
-- ijg_diep_2013/{z}/{x}/{y}.png
-- seamark/{z}/{x}/{y}.png
- mbtile provider:
-- cemt/{z}/{x}/{y}.png
@Gabi: view-source:http://maps.grade.de/ol3.html
(sorry for the mess, I am no pro)
just emailed Tim http://www.teamsurv.eu
- it is a nonfree project
- contributors may use the data for free
- commercial users have to pay
- non commercial use is a "grey area not defined fully"
But Tim is sure, they could supply a WMS feed to us to have a depth overlay layer in case we do encourage our users to log and share tracks.

Just got a reply from Yohan:
Dirk:
"OpenRiverboatMap is in favor as inland base map. Do you mind using your tile server for a start?"
Yohan:
"Sure! Be warned though that I'm planning a refactor as soon as I have a bit of time, but the tiles URLs will remain the same ;)"
@Malcolm, vector tiles: Not vector graphics, post was on
raw data (feature=node|line-string|polygon + geometry + key=value list) and on device rendering ...
an other approach: Use of vector-tiles.
Did some tests with
- mapzen's water and landuse layers https://github.com/mapzen/vector-datasource
- mapbox-gl-js (some of the magic is included in ol3) https://www.mapbox.com/mapbox-gl-js/api/
It is fast!
Drawbacks:
- no raster tiles (needed to generate .kap charts ...)
- styling can be a pain
quick research at skipperguide (profile=all) :
Heinz-Schleußer-Marina > fails
Ruhrorter Yachtclub e.V. > Rhein-Herne-Kanal
Jachthaven Friese Hoek > Lemmer
Regatta Center Medemblik > fails
Pekelharinghaven > Medemblik
google (site:skipperguide.de):
Heinz-Schleußer-Marina > fails
Ruhrorter Yachtclub e.V. > Rhein and Rhein-Herne-Kanal
Jachthaven Friese Hoek > IJsselmeer and Lemmer
Regatta Center Medemblik > IJsselmeer
Pekelharinghaven > IJsselmeer
I consider a google-search as a helpful add-on.
The best way to do that is to add links to the various marina guides to the harbour object....
Disagree:
- adding and maintaining links to OSM-db will be a pain
- this also applies to seperate 'harbour-db'
Example:
- click on harbour icon 'Alter Hafen Wismar'
- pop-up key=value box
- offer 'search skipperguide' button/link
- do query (new window/tab)
-- eg. https://www.google.de/search?q=osm+tags … erguide.de
-- or https://www.skipperguide.de/mediawiki/i … l&redirs=1
-- ...
yes, Olaf also implemented the overpass.api query (so (only) the first part is done).
I am asking for extending this feature: Query skipperguide (or other sites of interest) on demand and serve the corresponding hyperlink...
There is so far:
- http://sourceforge.net/projects/opennautical/
- http://kap.grade.de/
- http://wiki.openseamap.org/wiki/OpenSea … rt-Bundler
Alway an issue:
- age of snapshots ( http://forum.openseamap.org/viewtopic.php?id=2053 )
- stress on tileservers ( http://wiki.openstreetmap.org/wiki/Tile_usage_policy )
- webspace, traffic
maybe we get this up and running?

summary:
* Olaf, Niko, Bernhard, Gabi prefer mailing list
* Dirk, Gabi, Malcolm do not mind use of forum
* Niko, Dirk like http://www.discourse.org/
openlayers 2 is dead, switch to ol3:
Gabi's map: http://openseamap.he1ix.org/openlayers3/map.html
my map: http://maps.grade.de/ol3.html
base raster-layers:
- openriverboatmap: http://fluv.io/#7/49.813/2.889
- INT-1 style
- OSM
...
raster overlays:
- seamark-tiles
- wms e.g.
-- Data-ICT-Dienst, Rijkswaterstaat https://www.watergegevens.rws.nl/
-- Waterwegen en Zeekanaal, vlaanderen.be http://inspire.flaris.be/geoserver/web/
-- NAUTHIS SkinOfTheEarth (BSH) http://gdiwiki.bsh.de/wiki/index.php/NA … _The_Earth
...
vector-layers:
- AIShub
...
functions:
- window.location.hash (rewrite URL)
- clickable objects > overpass.api query
- geolocation with map orientation http://www.camptocamp.com/de/actualite/ … ientation/
This looks like a suitable replacement for the default OSM base map. Is there an existing tile server that we could use or would we have to make our own?
They do have a tile server (rather slow). Yohan is a friendly guy and had no problem passing requests: I am using a proxy (tilestache) in case of my maps (maps.grade.de) and skipperguide's maps.
- my favorite inland base map: https://github.com/yohanboniface/OpenRiverboatMap
- http://tilestache.org/ is the tile server I prefer:
-- raster tiles
-- vector tiles
-- cache
-- proxy
...
Grüezi, I sure hope so!
