[Talk-GB] MapRoulette challenge to connect isolated highways

[Marjan Van de Kauter]

Hi Rob,

We identified the missing highway leads by spatially comparing TomTom's in-house road centerlines with the OSM road network, and validating the results using the available imagery sources. We did not make use of machine learning or image recognition.

Hope this helps!

Sure. No harm in having a look at these. Based on experience there are a lot of false negatives in this sort of exercise but we can take a look :-)

It would be useful if you could describe where the data has come from. For example is it from machine learning / image recognition or from GPS trace data?

Thanks,
Rob
