X3D結合地理資訊系統之研究

Abstract

本研究利用X3D(Extensible 3D)開發一個將地理資訊（Geographic Information Systems；GIS）資料轉換成三維立體模型的方法，並利用X3D的動態特性且將各個不同時間的地理資料，以動態的方式加以呈現的方法。本研究並將用X3D所開發的模式嵌入地理資訊系統ArcView的應用試窗中，讓使用者可以在單一的地理資訊系統中完成X3D動態的模擬。 本研究利用所開發的X3D動態地理資訊系統完成海岸波、潮流及其海岸變遷個別的3D動態模擬，並完成此三者的整合動態模擬，可結合地理資訊系統、數值計算結果與X3D提供3D的海岸變遷動態模擬。

The method of converting the data of Geographic Information System into a three-dimensional model represented by X3D(Extensible 3D) was developed in this research. The 3D dynamic simulation is rendering by the time series information of Geographic Information System and the dynamic features of X3D. The developed 3D simulation model is embedded into the software environment of Geographic Information System ArcView. The user could use the interface of Geographic Information Systems to do the X3D simulation. The simulations of the effect of wave, current on the coastal evolution were done by the developed X3D GIS model respectively. And the combined simulation of the effect wave, current on the coastal evolution was also demonstrated in this research. The model of combining Geographic Information System, numerical computation and X3D simulation is developed to provide dynamic 3D simulation of the coastal evolution is this research.
