Map matching based on multi-layer road index
Web17. maj 2024. · Global Positioning System (GPS) data are satellite-based longitude and latitude coordinates for which map matching with road links, which are electronic maps, may be used in traffic operation management. Various studies have been conducted to improve the accuracy of map matching; however, research on the application of map … WebA map is a collection of layers. A layer contains map objects with geometry and attribution. A layer's content is cut into tiles, for efficient search, map display, routing, map matching and driver warnings.
