Location is only set to markers on line, not points along line

The new line feature is very exciting, and I can see it draws lines from paths on the map.

However, when I press play, the location is only set to wherever the marker was set – is that expected?

If so, interpolation is my feature request!

– Thanks for keeping spoofing alive on iOS 🙏

If I understand correctly, it’s expected.

You draw the route and each marker will have gps coordinates. We do set location to each of those points and we calculate time to travel between points based on the speed selected.

Will need to have a look at how complex more math would be. What sort of “resolution” would you need between two points?

I’m testing turn-by-turn navigation so higher is better, but that can depend on speed of travel. Once a second would be plenty, so for walking that might be a point every ~1.4 metres.

The core UX friction is plotting; if straight lines made the math easier, straight lines would also reduce the number of points to be clicked. Anything to reduce the clicks!
