MapFan DB Road Map Database
Road elevation data
This is high-precision data for routing and GIS analysis, with elevation information added to roads nationwide.
The system incorporates approximately 1.3 million kilometers of road network, reflecting topography including bridges, elevated roads, and tunnels, enabling various simulations such as estimating EV driving range, determining gradients, and detecting areas that are difficult to access during disasters.
Its key features include maintaining elevation values in 1cm increments and representing smooth trajectories that conform to road structures, making it easy to use in logistics operations, disaster prevention planning, and other applications.
