SVG-Rendering

Actually Osmarender is not the only renderer supporting SVG rendering.

• Mapnik does (see Mapnik wiki). You can easily export SVG over Mapnik and the export-tab as well. Mapnik is also able to export into any other cairo supported file-format (see cairo website or wikipedia entry).
• Merkaartor has a built-in vector (SVG) and bitmap (JPG,PNG) renderer.

Seems to be resolved now on the page (a number of renderers mention SVG) -- Harry Wood 10:26, 8 February 2011 (UTC)

differences are...

I don't think this list of differences makes any sense because it usually only depends on a specific rendering styles (e.g. by using a specific rule in rule based renderers like mapnik or osmarender). It would be more useful to compare renderers by features. (Renderer-Feature-Comparison-Matrix, Features could be: style/rule based, can generate map tiles, output modes, ...) --Ferdi 15:48, 2 May 2009 (UTC)

Yes this page was recently changed by somebody who didn't really understand the difference between comparing rendering software, and comparing available map layers. I tidied that a little, but... well example images might be nice, but they are are taking up too much page and they are unpleasantly low quality JPEGs. Feel free to give it a good refactoring. -- Harry Wood 10:27, 4 May 2009 (UTC)

Lots of refactoring has been done since then (mainly by me). Regarding the images, they're smaller now, but they're still JPEGs. Also I think I would pick some more radical rendering examples to illustrate the point -- Harry Wood 09:15, 27 July 2010 (UTC)

Rendering map in desktop application

Maybe something like JMapViewer is what you're looking for (although it doesn't render from XML).

This is not the best contact channel to ask questions. You'd be better off on the Forum or Mailing lists

Features accepted but not rendered in openstreetmap

There are features listed in Map Features page but when tagged and uploaded, are not seen in the OpenStreetMap. The data exists when map data view is enabled but in the standard layer physical existence of the feature cannot be viewed. Example: man_made = kiln tag is an accepted tag and is listed in the Map Features page. I tagged an area with this tag and uploaded to osm but I was not able to see the mapped area but the data were there. There is a suggested rendering as well but I guess it is not implemented yet.

Basically, We represent the OSM community in Nepal and we are working on a project which include mapping kiln that produce bricks in our capital city. Pollution especially air pollution has been a main issue for quite some time in Kathmandu. According to Environmental Pollution Index 2014 published by Yale University, Nepal ranked second last after Bangladesh in terms of air quality and its effect to human health http://www.cen.org.np/uploaded/AQ%20Status%20and%20Managment%20in%20KV_Maya%20Factsheet%205.pdf and toxic chemicals such as polyaromatic hydrocarbons (PAH) from combustion in brick kilns and diesel vehicles (MOEST, 2005) adds to it. We need to map the data related to brick kilns and keep it open (upload to osm) for analysis of the data for possible actions. There are 98 users of the tag man_made = kiln according http://taginfo.openstreetmap.org/tags/man_made=kiln till October 16 2014. We want these to be visible in the openstreetmap so what is the procedure to make this feature to be rendered?

The "standard" OpenStreetMap style is shows quite a lot of different tags, but not every tag documented on the wiki. Sometimes we add new tags to the rendering (Sometimes we remove some). These days this process is discussed over on this github issue tracker. But we don't add all that many new tags to the rendering these days. We can't render every tag ever, and it's generally regarded that the style is a bit too cluttered and confused already. However you might raise a new issue on there.

But instead we encourage other people to develop new rendering styles with different stylesheets, running on different tile servers hosted elsewhere (we're decentralised!). You could try to set something up yourself. It's a fairly technical process. Guide to serving tiles on switch2osm.org.

And since a few people have gone and done this, there's a few different rendering styles so.... and this is what I would actually recommend in this case... you could have a chat with the people who maintain the "humanitarian" style, which you can see here. It has a lot of these kinds of quirky features rendered as icons. Again suggestions can be made as issues on github.

Of course rendering to raster isn't the be-all and end-all. Maybe its enough that the data is in there, and can visualised with queries like this

Standard Map rendering changes

Like the point above I want to change the rendering of the Standard Map (and I'm not signing up for yet another account (Github) to do this) - I want area highway primary/sec/tert to be the same colour as their respective ways (red, orange, yellow) - as residential roads and areas are (white).

I'd also like to see only one map offered as standard - remove humanitarian, cycle and the rest - just have an OSM Standard Map with an option to switch to 'custom(ise) map' which merely offers checkboxes for each feature so that we can choose what features are actually shown on the map.
