we use OpenStreetMap map layout, therefore if you think some location has an incorrect name, please read this post to get more information - https://community.windy.com/topic/4649/how-to-correct-errors-in-the-base-maps
you can see a full list of downloaded maps directly in the app here -
It is divided by downloaded maps and maps that can be downloaded.
Of course, if you are online and open Windy maps, all maps will show up, cause you have access to internet connection.
When you do not have, only downloaded 'offline maps' will be displayed.
There is no option to display only certain type of trails or no trails at all.
If you want navigate, you can choose a way how you will get there - (car, walking, bike) and select if it is mountain bike or road bike and so on.
Thank you for your suggestion, we will consider it :)
