Hi everyone,

I want to use OSM data as a basis for some routing calculations (i want to test something new with special constraints so using existing routing algorithms isn't an option). During the calculations I want to add some information into the OSM database (mainly in forms of new relations) that my routing algorithm came up with. For this purpose I want to setup a local OSM server (rail ports with postgres database).

As it's a rather long term project i want to update my OSM database from time to time using diffs. At this point I need some help.

Is it possible to apply diffs to a local dataset that was locally changed after importing? I think the issue would be that I have originally two seperate datasets (local and public OSM) that initially are the same (when populating the local database at first) but after that will be modified independently from each other. Is it possible to incorporate changes from the public OSM database into my private OSM data? If yes, what's the best way to do so?

I hope I was able to explain my problem and look foreward to your suggestions.

Thanks a lot!

Knowing how big approximately is the test area going to be would help.

For now it's not going to be bigger than southern Germany. The OSM file has roughly 1.3 GB
