This process, known as "snapping to roads", produces a series of objects that trace a path closely following the road network. The resulting data includes road names and their respective speed limits, pertinent to the traversed segments.
Moreover, the Snap to Roads API offers an interpolation feature, which refines the GPS points to create a smoother route that adheres to the road's geometry. This functionality is especially beneficial for asset tracking and enhancing data visualization in mapping applications.
[!Important] The GPS points must be within 6 kilometer of each other.
