摘要：

Aiming at improving deficiencies in multi-resolution two-dimensional expression of geographic information method, this paper studied method of multi-resolution 3D expression of geographical information, putting forward grid method to express different regional landforms separately and a method of expressing different regional ground objects on level of detail in three aspects as shape, texture and properties, plus an example to simulate and illustrate. Multi-resolution 3D expression of geo-information has broad application prospects in smart city and city planning, which has a certain exploring value for the massive information, for its expression and visualization.
