Abstract

The research and the construction of the simulation model of the real world is now a trend by many governments and organizations, national interest and investment in the long-term development. Today, 3D GIS has gradually replaced and supplemented the limitations of 2D GIS in the management, display, population management and spatial analysis in urban areas, urban large. However, in order to build a 3D GIS system requires a huge investment in machinery, equipment and especially commercial GIS software system. The cost of software license will be one of the obstacles to the construction of 3D-GIS, so the study and use of open source software for building data models emerging 3D interest and to limit the application of capital investment for the project. This study will show the open-source software application capable of data for the modeling of 3D-GIS.
