Just a quick overview of the list of organised corporate-level mapping activities in Singapore. I believe we should have discussions on these corporate-level mapping activities for both awareness.
The mappers mapping on behalf of Grab appears to be introducing no_uturn restrictions almost to all roads in Singapore. I have no idea whether it is even useful to add so many uturn restrictions to almost every road (even for one-way roads, service roads).
While some uturn restrictions for major roads are good and improves routing, I have some concerns on whether the excessive mapping of uturn restrictions are because they are paid per change.
