Exporting to Adobe Illustrator
Adobe Illustrator is a vector graphics package, popular in the graphics design and publishing world. This page details approaches to get OpenStreetMap maps into the ".ai" file format for working with in Adobe Illustrator.
Export Tab on OpenStreetMap.org
While you can export SVG files from the Export tab of OpenStreetMap.org, the resulting files are very difficult to edit, containing multiple clipped and masked images. All features are a single layer.
Maperitive can produce high quality (and small-size) SVG rendering specially designed for importing into Adobe Illustrator. It separates map features into SVG layers, takes care of not duplicating shapes and also renders text as normal letters (and not as graphic paths like Mapnik does). A sample SVGZ map of the center of Dublin: http://maperitive.net/samples/Dublin_center_AI.svgz (NOTE: you cannot open it in browser, use Adobe Illustrator instead).

The osm2ai.pl script takes OpenStreetMap data and produces an unstyled Adobe Illustrator version 6 file (.ai). You can then work on this in Illustrator to produce a finished map.
Given a bounding box, the script takes all the ways that pass through that area, and draws them (in a Mercator projection). Ways are grouped in Illustrator layers according to their tags. By editing the script, you can determine which tags go to which layers.
- The osm2ai.pl script — or — an updated version of osm2ai.pl (February 2013) that supports osm files edited by JOSM.
- Perl and the Geo::Coordinates::OSGB module, plus a few others you almost certainly have already.
- (for small areas) an .osm file covering the area you want
- (for large areas) an OpenStreetMap SQL database running on your own machine — typically, a MySQL database created from planet.osm by planetosm-to-db.pl or similar
Using the script
perldoc osm2ai.pl for instructions.
The resulting Illustrator file is version 6, which can still be opened in any modern version of Illustrator.
The file is wholly unstyled and unlabelled: the idea is that you make the cartographic styling decisions yourself. However, to help you, the tags (keys/values) are brought through into the file, so that you can see (for example) the name of the road. The keys/values are stored as a "comment". To view these (in Illustrator CS), open the Attributes palette to its fullest extent.
Each way is rendered as a single Illustrator path.
- Move to the "Export" tab
- Add constant scaling, etc.
In Potlatch, you can export to pdf and then open the file in Illustrator. You can do a find and replace to get rid of layers you don't need.
Various other approaches may be possible if you convert via other formats such SVG
