Hi @Jalalus , and thank you for asking
Regarding Road mapper you can read this post: Frequently Asked Questions: Road Mapper, where you can better understand what is Road Mapper for.
I really loved this program, with which I have added over 10k kilometers of roads so far.
Access to Road Mapper is restricted, and you have to apply to be admitted.
However actually new applications are not accepted
If (when) Google will reopen the applications you will find the link to the form in this post: Join Road Mapper and help people navigate better with Google Maps
The way to add roads in Road Mapper is conceptually very different from what you do with Google Maps:
- Road Mapper is limited to a small number of countries
- Roads are added within quadrants of about 780 meters on each side, preselected by the program
This means that you cannot choose which area of Maps to contribute to, but only which country
