Hi,

I'm a openstreetmap contributor , and i'm really happy to see such usage of openstreetmap data.
However, I have noticed that the map didn't have clear and proper credit. First of all you must clearly include te crdit for all contributors with a required sentence “© OpenStreetMap contributors”.
You must also make it clear that the data is available under Open Database License. You can mention this with a link to https://www.openstreetmap.org/copyright.

I already see the sentence about OpenStreetMap on About/Map. But this must be improved.
When the correction has been made, please let me know.
Thanks,
Denis

Hi Denis,
  Thank you for writing, as well as thank you for your contributions to OpenStreetMap.

 We certainly do not want to under-acknowledge or under-advertise OSM. And in fact you can make explicit changes to any of the text on the web site by suggesting edits on this page: https://docs.google.com/spreadsheets/u/1/d/11A0JWtWDZPWoNoOhcuevHd8nj_cyYLoO0kcUCSrmkpI

 However, we also don't want to suggest that the street-level data we're showing are actual OpenStreetMap data because, as you will see if you look in detail, that could cause considerable consternation. For that reason we offer a link to the OSM view from anywhere on our map.  

To be clear, we carry out considerable pre-processing and some topological simplification of the street network. This includes a lot of re-drawing of routes at the fine scale. 
 So, we're talking about properly acknowledging derived data. I'd be happy to try to do a better job of that, but maybe another round of your advice or pointers to recommendations would be helpful.

Interestingly, a new version in 2021 will likely be a lot truer to OSM, though with more missing ways rather many re-routed streets.

Thanks,
Chris

Yes, see this. Maybe clarify the original licence and copyright only on menu. I check with some other openstreetmap contributor's.

I can not edit sheets (it's OK with this)
