[OSM-talk] Mapnik v2.2.0 Released
I'm pleased to announce that Mapnik 2.2.0 is ready. Download at the source, as well as binaries for iOS, OS X, Windows, and Ubuntu at http://mapnik.org/download/ The is the first Mapnik release to support 64 bit feature ids enabling filtering on id and and rendering grids [1] of OSM data. This is also the first Mapnik release to provide an API for vector tiles, which is available in a standalone repo [2]. This release also includes many performance improvements and bug fixes. See the release summary [3] and changelog [4] for full details. Dane [1] https://github.com/mapnik/mapnik/wiki/MapnikRenderers#grid_renderer [2] https://github.com/mapbox/mapnik-vector-tile.

Re: [OSM-talk] [HOT] Fw: Disaster Preparedness Project
Samuel, It seems to me like rendering the actual pages would be easier (than actually rendering a large image, then chopping). This should also give better results because the scales of things like text and lines would look better. So, the way I would approach this would be to determine the size and extents of each map for each page (ideally automatically). Then render each one with Mapnik. So, your ingredients would be a width and height in pixels, and bounding box for each page. Then write a python script to loop over every page and render a map using an OSM stylesheet. If you don't have python scripts skills then we can think of alternatives, but that would be my first recommendation. Mike Migurski, also author of safety maps, has done this with Mapnik for printed bike maps of SF, so he could likely advise.

But I've not really gotten past proof of concept. One usecase is making a map of every feature in a dataset that meets some criteria. I wrote a script a while ago that demonstrates how to do that with mapnik by querying all countries over a given population and them rendering a map for each, while painting a special outline over their border. Code is here: http://mapnik-utils.googlecode.com/svn/example_code/map_sequences/ and an animated gif to demonstrate what is done is here: http://dbsgeo.com/tmp/mapnik_animated.gif Can Mapsomatic easily be modified for different formats/scales? It can be done but I've found that hacking around in MapOsMatic requires a lot of patience and pretty high python/cairo skill level. http://www.safety-maps.org/ was a recent project to do something similar.

The actual rule is: treat it as a single OSM way and then decide how often to repeat the name for longer ways. This might not be a problem with residential roads on lower zoom levels, but it will with e.g. motorways on higher zoom levels. Look example [1]. There is no name on the motorway (I've got my browser about 1100 pix wide). I have deliberately cut a local stream up to make the name render in more places. It's up to the renderer to decide how often to repeat the name. In the case of Mapnik, labels are repeated along lines by default, but its up to the stylesheet author to specify the spacing between them. So, it is the rendering rules in question really, not the renderer. Cutting up ways just to make it look better for a certain renderer (Mapnik) isn't really a good practice. And it not needed at all if Mapnik is the renderer. And anyway, this depends on the zoom level: once you zoom into enough, you will still get ways that will be long and with one label only. And if you zoom out, you won't get _any_ labels, since the split ways will be too short to show anything.

So, if filters change and you've not updated your osm2pgsql style Mapnik will now let you know rather than giving you a blank map. The Map element now has a new optional attribute called 'minimum_version' which allows you to gently enforce the Mapnik version the style depends on. Mapnik development is moving quickly adding useful features, so this should be handy. Unifont, which is used as the fallback font to support CJK fonts in osm.xml, is now installed by default in Mapnik's font cache.

Do you know how to go about applying this kind of style to qgis maps? Thanks Felipe, That is the Mapnik stylesheet that OSM uses on the main slippymap page, opened in QGIS through the Quantumnik plugin. Quantumnik does allow you to author styles from scratch through the QGIS graphical interface, but also allows you to open existing styles (READ ONLY). So, that style is not authored by QGIS, but rather by hand by the brilliance and hard work of many OpenStreetMap contributors. Again, all Quantumnik is doing is allowing you to browse the maps rendered by that style inside QGIS and that requires you also have OSM data inside of PostGIS running locally. For more details see: http://svn.openstreetmap.org/applications/rendering/mapnik/README Overall the steps would be: 1) Install postgres/postgis/mapnik 2) install osm2pgsql 3) download osm data 4) import into postgis using osm2pgsql 5) edit the 'osm.xml' style to fit your database configuration 6) test rendering the osm.xml with 'generate_image.py' or 'nik2img,py' if it works then you have a Mapnik/OSM rendering setup running locally and you can open that style in QGIS.

I'm indeed hoping we can use this something this year. http://trac.mapnik.org/ticket/180 Yes, thanks Lenndard. Anyone interested in line offsets, please post your ideas to that ticket. I'm going to be working on the patch one last time next week. Dane ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
Re: [OSM-talk] rendering some large maps, e.g. whole world
Holger, Great script for modifying mapnik symbology for higher/print resolution, and awesome to hear that you are using Cascadenik. Just a note that I've started to work in Mapnik core for supporting scaling based on variable resolution output: http://trac.mapnik.org/ticket/343 - Dane On Apr 18, 2009, at 3:18 AM, Holger Schöner wrote: Hello, 2009/4/18 Torsten Mohr tm...@s.netic.de I'd like to print a map of Germany as a poster. My understanding is that osm.xml is configured to create maps that look fine on a screen. But the Pixels per Inch on a computer monitor are different compared to the PPI on a printed poster. So e.g. text size, symbol size and others may not look optimal when printed. That is correct. I wrote a small script (in Ruby, BSD license) to modify an existing mapnik style by scaling all text sizes, line widths, min/maxscaledenominators etc. It worked quite well for me (using the standard openstreetmap mapnik style) when I tried it some months ago. Link to script: http://www.ancalime.de/images/scalestyle.rb One caveat, though: As the icons are included as pixel graphics, and I do not know of any possiblity to scale them using style file syntax, they are not modified. Thus they will appear much too small on a printed map. If you have better icons, you might be able to adapt the script such that it exchanges yours for the standard ones ... For an own map (which also uses cascadenic style preprocessor to produce the mapnik styles), I created a set of icons in different pixel sizes (converted by inkscape from SVG templates mainly from the OSM SVN), where the size is included as suffix in the filename. With another script (much more complex, so I cannot publish it right away; but if you are interested, I might be able to produce an excerpt of the relevant parts in about two or three weeks) I can parse these filenames, and look for appropriately sized icons in their directory. Hope this helps ...
