Can maps from user generated content never be as good as maps made by experts?
There are two camps: One is the idea of the richest map. And the richest map could be every restaurant on the map, every tree. You can map the number of attributes, it could be the number of fire hydrants, the number of dog parks. You are still going to be able to rely more on crowd sourcing but the big map companies say: 'You need to have our more accurate map.' But what's even more important is real time. The time based map. And our lives are so busy, we are constantly trying to figure out how we navigate, where we want to go, and there is absolutely no way that an expert can scale to the level of 14 million drivers, never mind 50 million or a 100 million or 200 million drivers. It's obvious that the more data, the better, but I would say that the crowd source services have not been very good at filtering the data before and have given an argument to the traditional companies that the data quality is not that high.
