When it comes to mapping data, the flow is usually downhill: from the mapping data providers to the companies providing it to the consumers (GPS, online maps). The problem, of course, is that the map data may be wrong or, thanks to the time it takes to traverse the chain, years out of date. Yesterday, though, Tele Atlas announced something that allows us to talk back to the data: a map feedback form called “Map Insight” where we can submit corrections. Which makes the relationship a bit more two-way. In limited release, with similar error reporting forms to be made available through partner sites — presumably this means that the online mapping services will have error reporting forms? Very good if true. Via All Points Blog.
