Research About 3DGIS Texture Coordinates Data Management

One of the important factors to establish realistic 3D model and the scene is the texture data. The more real and complex of the scenes ,the more the texture data should be used. It is a problem that how to manage the texture data and image files effectively ,to avoid conflict,and to save display memory is what 3D urban landscape need to be solved. This article will put forward a feasible option on the 3DGIS texture coordinates data management responsed to these issues.
