Again about cards
Recently I looked through a map of the surroundings of my work with the help of the remarkable resource piter.nakarte.ru and to my surprise I found quite a lot of inaccuracies there. The map indicated a street that does not exist in nature (although it was in the area of ​​building up the area), and the geometry of the other two did not correspond to reality. I would love to correct these inaccuracies using my GPS tracks, but alas. No
The only service I know on the Internet that provides the possibility of jointly producing and correcting maps is the Draw a Map project . But there the work is structured as follows: the responsible person is assigned to each section, to which everyone wants to send their tracks with a description of the places where they disagree with the map, and he already makes changes (when his hands reach for processing your track).
If we imagine the perfect mapping service, then something like Wikipedia seems to be (or rather, its new version, where there is not much anarchy). There are enough GIS extensions to free databases for storing geo-information. There are more or less accessible vector map editors, with the authors of which it is possible to agree on the adaptation of their solution to the new service. If we organize the storage of a vector map in such a database and a mechanism enabling users to make changes in this database with the help of a certain client, we will get a really good map. Which everyone can correct and add.

Yes, the idea is slightly utopian. Yes, it requires serious study and in terms of developing a uniform and convenient data format, both in terms of security and in terms of moderation. But it seems to me that it is viable.
You can even go further and imagine that one of the attributes of the object “road” is an assessment of its quality (or an estimate of the average speed of movement on it). Which is calculated as the average rating of all voters. You drive down the street, mothers of the pit and potholes, you can immediately put an estimate on the navigator so that others don’t get here unnecessarily ... And then you can make a route considering the quality of the roads. But this is already so, dreams.
Well, gis-market players, who is the first?
