It might be worth mentioning this on the export page itself.

In any case, excellent work.  I'm going to have to start investigating the 
use of the main OSM codebase for the OpenPisteMap website - things like 
the export tab would be extremely useful there.

Indeed. Absolutely delighted to come back and find this had appeared -  
turns out we've been discussing export to PDF for two years now, which  
is eons in OSM terms:

I'm looking forward to delving into the code (when Potlatch 0.8b is  
out of the way) and examining the possibility of adding unstyled  
Illustrator export.

- Is it possible to export larger chunks of the maps at the maximum

I guess the size of the export really is a question of performance, as 
there's only a finite amount of processing power that can be devoted to 
the export functionality. If you need such larger chunks, you could try 
and download successive bits of the extent you need and paste them 
together again, or write a custom script that directly downloads the 
relevant tiles. Also, you could try Kosmos as an alternative rendering 
engine.


(WARNING DWEEB QUESTIONS)
- Is it possible to import the XML-file into Illustrator?
- When I use this map, how can I tell the scale and projection when

scale manually. Would that be enough to get that professional touch?
The projection issue would be solved by the integration of world files 
or geoaware formats as proposed. I guess thats a job for phase two.

Re: [OSM-talk] New Export Tab

2008-04-21 Thread Juan Lucas Dominguez Rubio
Hello, Axel :
 
The scale bar provided currently (April 21, 2008) by the main browser at 
www.openstreetmap.org is wrong. The image you get with the Export tab has no 
scale bar, so I recommend to use the Export tab and compute the scale bar 
yourself.
 
More details:

No, because it would be too computationally expensive to produce
such maps. In the case of the bitmap images it would require vast
amounts of memory and in the case of the vector images they would
be unusable even if you could produce them as the files would be
so large that rendering them would take forever.

> (WARNING DWEEB QUESTIONS)
> - Is it possible to import the XML-file into Illustrator?

Not unless Illustrator has magically gained an understanding of
OpenStreetMap XML data while I wasn't looking, at that seems
extremely unlikely.

Your best bet will be to take the mapnik SVG/PDF/PS image and
import that - Illustrator should be able to read at least one
of those.

The scale will be (give or take) what you asked for in the case
of mapnik - there is as I explained yesterday one possible issue
over the question of DPI assumptions with the vector formats.

With the mapnik bitmaps formats, if you assume the bitmap to be
a 96 DPI image then the scale should be what you asked for I think.

The projection is the Google spherical mercator projection for
both mapnik and osmarender images (aka EPSG 900913).

And another lolcat goes to TomH :)

The idea was floating around for some time but I think he really has
done a good job here. I wasn't expecting the export tab to work that
way but I really like how he's done it! Easy and nice to work with.
Congrats.

+1. I guess it was TomH's work and there's no reason not to announce 
such a major development on the lists (for the benefit of those who 
don't use the trac RSS feed). If it hadn't been for Andy's mention I'd 
probably still tell people to download map tiles and glue them together 
if they want a quick bitmap ;-)

Apart from being useful to create a default styled map, the Export tab 
gives me the excellent rebuke to anyone who says "why don't you use 
Google": "Sure, where's *their* Export tab?".

Good work!

Bye
Frederik

I want to (re)make a WMS server on top of OSM data, using mapnik and/or 
osmarender as a backend. Unfortunately, I can't find the time to get that 
idea out of the back burner.
