Well, ignoring for the time being that little dig about what might or might constitute "professional looking", the problem (as I understand it) is that none of those formats is, in and off them themself, enough for an export format. What I mean is that you can't just say "export to a shapefile" on it's own - you have to define some sort of style that controls what attributes you put on objects on the shapefile (or KML or GML file) and how those are derived from the OSM data. I do have some plans for additional formats, but none of those are high on my list. If on the other hand somebody wants to provide a web service that returns such data for a given bounding box, then it is relatively easy to add them to the UI.

Re: [OSM-dev] [OSM-talk] New Export Tab
The problem with Shapefile support is that the datamodel of OSM is not very well suited for direct translation into Shapefiles. there are several issues: A shapefile only supports one feature type. So one export would need to have at least two (ideally 3) shapefiles for points, lines, areas. Areas (polygons) are also only defined through the tagging scheme, so any converter will need to be constantly updated from the wiki page to correctly identify and convert lines to areas. The data schema with its multiple tag value pairs as well poses some problems. The shapefile will need to include columns for all tags included in the export. This impacts negatively performance importing and processing shapefiles. Also, multiple values for the same tags pose a problem in such a scenario. I have personally developed a import script for OSM XML data (obtained from the API) for the Manifold GIS software. My workaround for the performance issue with multiple columns was to only retain the OSMID in the actual Geometry layer, and save all tagging data in a separate table as OSMID, tag, value triplets. One can then join back relevant tags as needed. I dont know about the data structure of KML or GML. as these are XML as well though they might prove easier?

Thanks (WARNING POSSIBLE FEATURE REQUEST) - Is it possible to export larger chunks of the maps at the maximum level of detail? 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.

No, it doesn't. My original expectation was that I would have to do that, but it turned out that everything was so fast it wasn't necessary so I did the "simplest thing that works" and didn't bother with any queueing technology. Thinking about it more, if you allow requests that are so slow they have to be queued then you things get vastly more complicated because you have to start worrying about how to manage the queue and ensure you don't accept more requests than you can actually process.

Indeed, I think it would be dead easy to do an mkgmap export, although generally speaking you want quite a big area for the map which might not mesh with the same print views.

There is already a tool for exporting .osm to .kml in the SVN repo. Last time I checked it did work fine. As for GML, it should be able to hold a variable number of tags (key/value pairs).

Well you could just have it submit jobs to an external queuing system but it would need quite a bit of work to integrate neatly, and I'm not sure I would to tie an external service like that tightly into the official main site. > However if export to Garmin could run on the OSM servers, that would be > easiest.
