Sven, Brian, There are two reasons that this only works for the UK (or really the UK and Ireland) at the moment:
- My OSM database only covers this region. It could probably cope with a larger area (maybe Europe), but I have never tried - it is running on my old Laptop so it is not particularly powerful (but does use <20W, and I worry about my Carbon footprint!). - The method that I use to produce the map would not scale well to large areas - there is a single file for each feature for the entire area, so if I make the area larger the download time for the files could become very large, and make the map feel unresponsive. (I think that I will struggle even to extend the maps to uk pubs, because the pub data file is over 9MB, which would need downloading every time a user views the map. There are ways around this: - Split the data into different files for different areas (basically cut it into tiles like we do map images). - Use a database on the server and extract only the data covering the area being displayed - could be done, but I do not have the code to keep a mySql database on a remote server up to date with OSM data. I think that these could be solved, but it will mean a change to the data handling system. If you are interested in developing one of these, let me know and we can collaborate on it.
