[OSM-dev] [osm3d] rendering area data
Hey all, There are quite a few devs working with OpenStreetMap data in 3d and judging from screenshots, they've been able to do some pretty awesome stuff so far. I'm trying to do something similar and wanted some feedback, specifically for rendering area data, that is, anything that falls under the 'area' primitive in terms of OpenStreetMap data -- buildings, borders, etc. I'm particularly interested in how to convert area/relation information from *.osm xml data into polygons that can be rendered (decomposed into triangles). Starting from the osm area primitive info [1], it's possible to get contours (ie node lists) for outer geometry and holes within the area. This data can then be fed into something like poly2tri [2], which is a lib that will triangulate simple polygons (holes can be specified too). The triangulated data is a mesh that can be fed into any renderer, like OpenGL. However, we can't assume all area data are simple polys; [4] shows some building geometry that's not strictly simple. So my main problem/question to devs that are rendering buildings/area geometry in 3d is: * How do you build the 3d geometry for areas that are potentially complex polygons?

Hello, the servers my tools are hosted are on the ones I have availabe, I would love to have a dev account on osm, can you please make me an account and I will install my tool there. thanks mike On Sat, Mar 31, 2012 at 11:05 PM, Serge Wroclawski wrote: > H.S., > > It means that while the database is in transition, no additional > uploads can be performed.

Re: [OSM-dev] Training during read only database period
H.S., It means that while the database is in transition, no additional uploads can be performed. This really isn't a dev question, so it should be going on the talk list. But I want to point out to you, like Toby has, that none of the services Mike Dupont has pointed you to will result in your data going to OpenStreetMap, but rather to OSM competitors. Mike, you should make it clear to a use who is asking about contributing to the project that these servers/services you're pointing out are *not* OpenStreetMap, but are in fact competitors to the OSM project. - Serge ___ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev

For the record, I am working on code, programs people can run on their own. my API server can be run on any linux server and you can connect and client to it. > code is here https://github.com/h4ck3rm1k3/FOSM-Api, you can easily set > it > > up, requires no database, the only thing that is hardcoded is the path > where > > it writes the output, i will have to make that configurable. > Lets keep the discussion on dev to be technical, I am working on free software that is usable for all people and not tied to a specific server. if you need help to install this yourself, let me know. I am working on tools to make osm totally decentralized so we dont need a central big database server, and I hope that the osm project will benefit from this. mike ___ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev

FOSM is a fork of OSM data performed by a few people who were not happy with the license change and decided to make their own OSM-like project that will remain under a creative commons license. Also, last I knew they didn't do live rendering of changes so that may not be as useful for your purposes. If you were planning on using JOSM, you should still be able to download data and make changes locally. You just won't be able to upload them. I'm not sure if Potlatch will be available at all or not. One thing you could do is download data and edit it in JOSM and then save it out to a file on disk and render it locally using, for example, Maperitive. I have a blog post about using Maperitive if you would like to investigate this more: http://ksmapper.blogspot.com/2011/08/simple-openstreetmap-tile-rendering.html Toby ___ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev
Re: [OSM-dev] Training during read only database period
Yes, we have the fosm.org server you can use commonmap.com and I have today implemented a test server with a fake oauth that allows you to edit with potlach, josm and merkaartor code is here https://github.com/h4ck3rm1k3/FOSM-Api, you can easily set it up, requires no database, the only thing that is hardcoded is the path where it writes the output, i will have to make that configurable. The potlatch is installed here you can try it. pine02.fosm.org/random.dev.openstreetmap.org/potlatch2/potlatch2.html the api root is here : you can configure your client to use it. pine02.fosm.org/FOSM-Api/OSM-API-Proxy/public/dispatch.cgi, the changesets are written here : http://pine02.fosm.org/FOSM-Api/OSM-API-Proxy/public/changesets/ let me know if you need any help. mike On Sat, Mar 31, 2012 at 8:15 PM, H.S.Rai wrote: > Can anyone help me on my comment: > > "We have also planned an event in which particpants from various > country are involved during this period.

[OSM-dev] different rendering with mapnik based on area?
Hi there,
is it possible to have different rendering rules based on the area
where rendring takes place using an ordinary mapnik rendering stack
(osm2pgsql+mod_tile+tirex)?
What I would like to do (for now) is implementing a name rendering
logic for the german mapnik style:
name outside europe: coalesce("name:de",int_name,name)
name inside europe: coalesce("name:de",name,int_name)
A rough bounding box around europe would be good enough for this
purpose.
Sven

Hi, Is there a reason why a 'way' can contain more than one linestring in a osm2pgsql import to postgis? # select geometrytype(way) from planet_osm_line where osm_id = -2000800; geometrytype -- LINESTRING LINESTRING LINESTRING LINESTRING LINESTRING (5 rows) An additionnal question, is, what is the purpose of the -G option at import?
