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

Hi,

(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

visit

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:
https://forum.opennauticalchart.org/viewtopic.php?id=12

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?

#16 Re: general discussion » online map » 2015-12-22 10:27:47

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

#17 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
    http://tiles.openseamap.org/seamark/world.osm
I do not know about his change-set routines ...

#18 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'.

#19 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?

#21 Re: online map » Development previews for maps » 2015-12-20 13:10:18

sorry, I was thinking about tile serving. Shall we start a new topic at 'development > general discussion > tile server'?

#22 Re: online map » Development previews for maps » 2015-12-20 12:53:12

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

#23 Re: general discussion » Forum timezones » 2015-12-20 12:43:57

Hi Shawn,

there is 'UTC +8:00 Greater China, ...'

Have a nice day, Dirk

#24 Re: general discussion » (No) new project? » 2015-12-20 11:20:49

We might start stating what each individual expects and wants to achieve.
Here comes my initial try https://wiki.opennauticalchart.org/inde … rk--#Goals

#25 Re: general discussion » online map » 2015-12-20 10:48:30

@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
