Re: "OSM map with a one percent of roads is far worse than having 101%
of the roads mapped with the help of AI with 1% of extras, because
fixing that 1% is far less work than adding 99% by hand"
I'm not certain this is true. It might be very difficult to find the
1% of incorrectly mapped roads; you don't know where to look, and you
must survey on the ground with GPS, and check each road segment to
find the 1% that actually are blocked by a fence or gate or don't
really go through that clump of trees.
In contrast, when 99% are missing it's very obvious when looking at
the map data. You still have to survey and add the streets, but it may
actually be faster to get to a complete map of your home neighborhood,
than trying to find 10 bad streets out of 1000 segments in your
Finally, when you look at the map and it looks 100% complete, you
won't see the need to start mapping and become a totally addicted
OSMer like you will if your village is only 1% mapped, so we may not
get the new contributors that we need to actual maintain the data that
our robot mappers have added.
