This is the imaginary database but Google knows a lot more than that.
There are also vectors for the roads, with a link between that data and streetview. You can click on the map and google will tell you that you're at 24 Burgess Street, and show you a photo, so it has a link between all that information.
I suspect they also fuse this with information from phones. Do the phones contribute to live traffic stats? Or the information about when a shop is busiest (it will show you a bar chart of when a gym or store is busy). Is that done based on knowing when android users are at that location? What about all the Wifi access points it knows the location of?
In some ways, this is much harder to deal with than the image data because although it's smaller in size, it's denser in information and the links between are more complex.
- rdtsc 11y agoI understand that compared to raster images vector data for roads is negligible. A dinky Garmin car nav system from 2011 I had held continental US road system data in a few gigs only.
- Doctor_Fegg 11y agoOpenStreetMap's vector data for roads (and buildings, landuse, etc.) for the whole world is currently 31GB, in OSM protobuf format: http://planet.osm.org http://planet.osm.org

You can click on the map and google will tell you that you're at 24 Burgess Street, and show you a photo, so it has a link between all that information. I mean, you can now download your local area's data to your phone from google maps. I suspect this size is negligible compared to the raw 2d/3d/historical data. It would have been nice to include it in their analysis, though.
- SEJeff 11y agoGoogle's purchase of Waze is one of the main ways they get realtime traffic data: http://www.businessinsider.com/how-google-bought-waze-the-inside-story-2015-8 http://www.businessinsider.com/how-google-bought-waze-the-in... For serious drivers, there simply isn't anything on the market (and free!) better than Waze.
- Raphmedia 11y agoAre all the features on Waze in Google yet? Or should I download Waze?
- jessriedel 11y agoYou can't contribute information without Waze, and you don't get some notifications like the presence of speed traps. But the Google Maps app has the key traffic information after coarse-graining and filtering.
- y4mi 11y agothey have different target audiences. waze almost gamifies driving and tries to get users to actively report stuff about the traffic, including accidents and similar things. google maps is a traditional navigation system with live traffic monitor, but ultimately a passive experience. afaik no feature of waze has been nor is planned to be merged into google maps. the live traffic monitor of google maps was already available significantly earlier than the waze acquisition.
- SEJeff 11y agoYou should likely download Waze if you want the best experience. That being said, using google maps, you'll see traffic updates or maintenance/cops/red light cameras and it will say "Information from Waze" or something akin to that.
