构建全国三维虚拟草原关键技术及方法研究

本研究综合运用草原生态学原理、3D-GIS技术、遥感技术、数据库技术及软件技术等现代相关技术,探讨多元空间信息和属性信息的组织方法,摸索多元生态信息与三维虚拟地形模型的关联技术,得出相应的多元生态信息有效管理机制。研究表明:运用C/C++语言调用OpenGL图形库从底层开发的草原三维数字模型快捷稳定,渲染速度快,可方便地动态查询示范区草原地理信息,为进一步研究三维虚拟草原提供了技术支持。

Study on Key Technologies and Methods to Construct the Nationwide 3D Virtual Grassland

Based on comprehensive use of grassland ecology principles, 3D-GIS technology, remote sensing technology, database technology, software technology and the other modern related technology, this study was to explore how to organize multiple spatial information and attributes information, to find the relationship of multiple ecological information and 3D-virtual terrain model, and then to obtain the effective management mechanism of multivariate ecological information. Study showed that grassland three-dimensional digital model developed by using the C/C++ language to call OpenGL graphics library worked fast and steadily, owned quick rendering speed, and provided real-time and dynamic query of grassland information easily, which could supply technical support for the further study on three-dimensional virtual grassland.
