Jean-Guilhem,It sounds like there could be a lot of demand for the ability to generate these map booklets.Thomas - are there any updates on this effort from the MapOSMatic side of things?I am working with a group of designers on the disaster prepardness project so we can definitely contribute design resources.-SamuelOn Tue, Jun 7, 2011 at 3:08 AM, Jean-Guilhem Cailton <address@hidden> wrote:
After the recent flood in Haut-Richelieu, Québec, and the request to use MapOSMatic in this context, it happens that I met Thomas, one of the developers of MapOSMatic.
When I had asked about this functionality of map booklet, he had told me that they had started working on this (or on features that would make this easier, I don't remember exactly) during the Hackfest last August.
Maybe coordinating efforts on this would be the best way to move forward?
By the way, he also told me that he had sent an email reply, that apparently was moderated on lists he is not a member of, and that I have not seen. He explained that there was still a lag in the database updates (after the MapOSMatic database had been down).
About the mapping of a specific area defined by a relation (not necessarily a city), it might be not be too far from what is done with administrative boundary ways, but would require a mean to transmit or specify the desired area.
Anyway Samuel, I invite you to have a look at http://www.maposmatic.org if you have not already (there seems to be a problem at the moment with a job over Berlin, hopefully not for long).

As mentioned before it would be ideal if this could be automated so that all it would need is a city and it would produce the pages. Anybody interested in helping create such a system?

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.

Making mapbooks easier to script, via python, with Mapnik has long been a goal of mine.
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:
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.
Can Mapsomatic easily be modified for different formats/scales?
safety-maps are awesome.
