When there are new roads being built, how do navigation systems like Waze or Google Maps know about them? How do they add the roads? Do they add them manually or is there some smart way?

Most GPS maps have an option to make a report. If you have a new road, you can click on whatever the symbol or drop down is for making a report and fill it out according to the directions. New technology is being added all the time, and some new in dash GPS will be sending data 2 ways and all you’ll have to do is drive down the new road for it to be added.
