Hey ftrebien,

Please explicitly mention any sources you are using in the changeset source field when saving your changes. Sources like "more recent maps" and "various photos" are unclear and as such not verifiable.
https://wiki.openstreetmap.org/wiki/Verifiability

Note, sources may or may not be compatible with the license OpenStreetMap is using; aka we may or may not be able to use the data in OpenStreetMap. See
https://wiki.openstreetmap.org/wiki/Import/ODbL_Compatibility

As noted on the OSM Wiki, not all data sources listed there are known to be compatible.
https://wiki.openstreetmap.org/wiki/Antarctica/Data_Sources

- Data sources available in the (Rap)iD or JOSM editors by default in their imagery or data menu are allowed to be used for mapping in OSM.
- Licensing for Wikimedia Commons or similar imagery may vary.
- Google Maps / Google Streetview / similar proprietary services are copyright. See
https://wiki.openstreetmap.org/wiki/Google
- Facts in news articles may be used, though with caution.

Note, I can't give legal advice nor guarantee anything is ok to use.

If you are unsure if you are using compatible sources, please contact the Licensing Working Group.

If you are using incompatible sources, please contact the Data Working Group to have it reverted.

This message is just for your information. I assume you are using compatible sources.

I also invite you to check out the (global) contact channels if you haven't yet.
