Dear Frederik, dear Paul, Thank you for your message! I suppose I made the mistake of asking for a technical fix, rather than fully explaining the problem...
I have 40 small, discontinues areas in Ghana (the 40 public colleges of education), like this http://www.openstreetmap.org/way/450562441#map=16/7.4129/0.4631 and I want to produce print. The files itself will be downloaded locally (or emailed), and then printed locally. So the file needs to be small, and print resolution (say for A2 or A3). We're actively editing this at the moment (and have been over the last year), so we'd like to print from up-to-date data. Print + small files, means PDF, as its vector, and can be printed at any size. I assume PNG at 300dpi, A3, would be massive. There aren't loads of areas, and manual export would be ok. However, because the areas are discontinuous, I am looking for a solution where I can work from lat/lon, rather than having to manually select areas. Once this would be ok, but we'd like to be able to repeat the export later. Most tools don't allow you to go back to maps that you've already produced, to reprint simply with data a year on. > https://operations.osmfoundation.org/policies/tiles/ > ... so using a script to produce these PDFs would violate the policy except > in rare circumstances where running the script is triggered by a user > request. > I'd be quite happy to click manually. At the moment, I enter the values for scale manually, resize the browser window so it gives me the right nominal dimensions (for PDF), then export. However, it would be helpful to have a preconfigured link, that gives me my settings (scale, dimensions). > > * download and stitch tiles, convert to PDF; search for "OSM bigmap" for > different implementations. * use the "staticmap" script on openstreetmap.de like this: > http://staticmap.openstreetmap.de/staticmap.php?center=40,-50&zoom=2&size= > 500x350 > > Both will only give you standard resolution raster images.

Thanks both for you input - much appreciated!! Bjoern
