Comparison of route planning using 2D versus 3D road networks. (IMAGE)
Caption
Route planning results from point P to point Q using constructed 2D and 3D road networks. The orange line shows the generated 3D road network, while red and blue lines represent path planned based on the 2D and 3D road network, respectively. The green-to-while gradient of the background refers to the DEM elevation information. The figure demonstrates significant differences between the shortest paths planned with and without elevation data. The 3D road network provides more realistic and accurate route planning by incorporating elevation information, which can avoid potentially impractical and inaccurate routes that may occur when using 2D road networks along.
