I have set up an OSM tile server and also an OverpassAPI on my own server. While I was doing that, I understood that OpenStreetMap provide minutely, hourly and daily updates. So my servers can be sync with it. On the other hand, I want to add my own private data into my server without pushing them to OpenStreetMap servers. My question is that can I have a tile server(or OverpassAPI server) that feed from both sources(my own private data and periodic updates of OpenStreetMap)? Any assistance would be grealty appreciated. Note: Technically speaking, I am really confused. I have couple of questions but the most one is that I don't have any idea about ids. I know that OpenStreetMap data(nodes, ways and relations) have positive ids and therefore my own data could get negative. But is it a real solution? *This is a recap of my question in StackOverflow([here][1]). There are also some similar question([this][2],[this][3]). question(i.e. [this][2],[this][3]). None of them have accepted answer.* [1]: https://stackoverflow.com/questions/58055581/osm-tile-server-combination-of-my-own-private-data-and-openstreetmap-priodic-up [2]: https://gis.stackexchange.com/questions/172316/osm-update-without-losing-own-additional-data [3]: https://gis.stackexchange.com/questions/295767/keeping-my-changes-up-to-date-with-osm
