With the appearance of the realistic structure model in the quantitative remote sensing research on the vegetation

the visualization of the structure of the vegetation has become an important aspect of the realistic structure model. In the process of the research on the realistic structure model

a 3-demensional visual data model is developed to construct the structure of the vegetation. The data model is based on the object-oriented approach and builds the geometric and logical relation among the objects through the object-combining

which is used to simulate successfully the scene of the winter wheat. The data model aims at providing the geometric and optical parameters for the RGM model and improving the accuracy of calculation of radiation of vegetation.
