Is that possible? A git repository is certainly not mandatory, but the existing scripts I mentioned needs this. If you don't want to create/use git for this purpose it should be easy enough to modify the scripts to use bzipped/gzipped extracts of a country. And if you do this change please share the scripts :), I know that a lot of people would like to use this approach. Frederik, we used a git repository for our Romanian extract for 2 main reasons: 1. the extract is a XML file so it should be straightforward to use a versioning system to take care of the history. 2. space constraints: the Romania history from late 2007 to the present is around 5GB in .gz format, and the whole git repository has 480MB, and this includes the latest extract, unpacked (260MB), so it's a big improvement. Valent, how you can get older data is explained very well by Frederik and Grant in this thread on Talk: http://lists.openstreetmap.org/pipermail/talk/2009-October/043705.html To be more specific, I used the following revisions of the scripts to get a pre 0.5 extract in the current format: - r4779 for osm-extract - r4778 for planetdiff - r4835 for conv05 Once you have the country format you can use osm2pgsql to insert data in the database, and you can filter the data to a specific box that will fit your city. Hope this clear some points and wil get you started, --Ciprian ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Is that possible? You can download *full* planet files from planet.openstreetmap.org and then use available scripts (from SVN) to extract your home town from each. A git repository, unless git has some magic properties that I am not aware of, does not change the fact that you have to extract the data from old planet files.

Can you explain how can OSM users then get a history for one city from old planet files, that would be really helpful. If this is possible then git repository isn't necessary, AFAIK, but I'm not the one who made the scripts so maybe there has to be a git repository. How can I get snapshots month by month for my home town from january 2006 to present day via old planet files?

I don't understand where the git repository comes in? I mean we do have an archive of old planet files already, it's not that stuffing them into a git repository would somehow magically select the region of your interest from them?

[OSM-talk] OSM Map Evolution (make your own "Year Of Edits" video)
Please check out this great blog post from Romanian OSM mappers: http://snipurl.com/svk0b Ever since I saw great ITO World animation "Year of Edits" I wanted to make my own version. This look like it is possible. Just look at the Bulgarian OSM mappers blog post. So in order to make this work they made git repository for planet file and that is how it is possible to get a history for some town or place, because git repository keeps all changes ever made. So in order to make your own animations you need to have your own planet.osm git repository. That is the first big hurdle :( I hope that OSM creates an official public git repository so that anybody can get "history" for his town/place. If/when we get history for some town what are the next steps? I'm still not clear what are the next steps needed. Is somebody more familiar with this? If you are please provide some step- by-step instructions. Here is the translation from Bulgarian blog post: "To help Eddy, it was requested to provide OpenStreetMap on national television, I took the scripts we use it and with minor changes (required to use own Mapnik installation) I was able to generate several films with developing the project OSM in Romania. The results are not terribly spectacular (see ITO World) but I think the record pretty well out of so many people work." And here is Eddys post explaining how these scripts work: http://lists.openstreetmap.org/pipermail/talk/2009-September/042646.html "The main ideas: - the planet files are stored in a git repo (in another branch than master - the scripts warn about this and give advice) - the generation of the maps is currently tailored to focus on Caracal, my home town where I was the author of he huge majority of changes; it would be nice if this was configurable by an external file, but I expect patches - you can commit anonymously in the mob branch :-) - the generation can go back from the most recent version of the planet file in the "planet repo" down to a date or down a certain number of commits - mapnik is used for generation and the database configuration stuff surely needs checking - the main script is "gen_dated_maps" which in turn calls "gen_map" - gen_map is the rename of gen_map_Caracal and should be the generic version of the map generator - the images are created in a ne directory _maps, and can be added an optional time stamp" -- pratite me na twitteru - www.twitter.com/valentt http://kernelreloaded.blog385.com/ linux, blog, anime, spirituality, windsurf, wireless registered as user #367004 with the Linux Counter, http://counter.li.org.
