A Vector Data Model for Efficiently Rendering Large Vector Maps on Global 3D Terrain Surfaces

Ganlin Wang, Jing Chen
2022 ISPRS International Journal of Geo-Information  
In the Vector Tiled Pyramid Model, vector data at different scales within the same geographical extent are stored as separate levels.  ...  In addition, this advantage is more evident when a vector tile at a lower level (large-scale) is requested and visualized on 3D terrain surfaces.  ...  The geographical scope of the city, such as Wuhan, is almost as large as the geographical scope of the vector tile at level eight of the VTPM in our experiment.  ...
