[Objective] Through studying three-dimensional(3D) modeling processe and method

we expected to provide solid basis for subsequent building of digital park. [Methods] Based on GPS mapping and ground survey of the park

visualization modeling was applied to the soil and water conservation project. [Results] Jiangxi Soil and Water Conservative Ecological Science and Technology Park was taken as an example

constrained triangulation and spatial interpolation were employed to solve some key issues. For example

seamless tiling of surface features and topography

soil body modeling

rapid generation of plant model

and so on. Finally a 3D model with aboveground and underground integration system including such elements as project measures

vegetation

and soil

etc.

was constructed. [Conclusion] The developed 3D visualization system can make the water and soil conservative ecological demonstration park playing a better role in scientific support

social promotion

typical drive and demonstrative radiation.
