What if the company has proprietary (better) road segment data extracted from their sensor network that they do not / cannot share?
“However, by sharing just the new road segment geometries with Overture (not the entire proprietary traffic feed), Overture will add it to the Overture corpus and generate GERS IDs accordingly. The Overture road network will be improved and 100% of the company’s data feed can become GERS-enabled.”
Would those “improvements” then be fed back into e.g. OSM?
