I was thinking about starting a new topic but let’s use this one to grab more information.
How can I edit a bike lane? I mean, the bike lane is dashed light green, but actually it is in the same road as cars but has a separation with pieces in the ground. I think it should be light green and in some parts even dark green because it’s totally separated.
Google Maps has a program enabling local and regional partners to upload their data directly and automatically. Please learn more here: Google Maps Content Providers
Examples include municipalities and public transport providers.
Where I live bike paths are imported directly from a database owned by the Municipality into Google Maps.
Hence I would never try to edit them on Maps. If I see what I think is an error I will reach out to the relevant department of the Municipality and have them fix the problem. Soon after the fix will also be shown on Google Maps.
To me your map could look like the same is going on where you live (I’m just guessing).
The How-tos section of Connect is the board where you can share your questions related to the Local Guides program or your Google Maps contributions. To keep Connect more organized, I will move your post there.
In addition to that, I am marking @MortenCopenhagen 's reply as a solution, so other Local Guides can refer to it. The purpose of this feature is to help Local Guides find answers when searching on Connect. Please take a look at How do I mark comments as solutions? article.
As well, I changed the title, so it will be easier for Local Guides to understand what the post is about.
I think this is, by far, the best method, and can address many missing trails/lanes at once. Most US cities already have good GIS data about their bike lanes and trails, they just don’t know about Google’s Geo Data Upload tool. In the US, most city websites list contact info for a GIS person or Parks & Recreation, so I email them the Geo Data Upload link and ask them nicely to upload their bike GIS data. In my experience, they often don’t have to do very much to their existing dataset before uploading it.
So far this year several cities have followed through after my email, and, as a result, there are now at least 10km of additional bike infrastructure shown in the Google Maps biking layer!
