基于VML技术的森林资源分布图更新方法研究

Research on a method for updating forest resources maps based on the VML technology

【目的】研究基于VML技术的森林资源分布图动态更新方法。【方法】以陕西省黄龙山林业局蔡家川林场的数据为例,将VML技术与当今最为常用的PHP和数据库技术相结合,提出B/S结构的森林资源分布图动态更新显示系统的设计方案。【结果】建立了基于VML技术的实时化森林资源分布图显示系统,并通过此系统动态生成了蔡家川林场的森林资源分布图。【结论】所开发的可动态更新的森林资源分布图显示系统,能给用户提供直观的图像信息,有利于管理部门更快、更方便地进行决策。

[Objective] This research investigated the use of VML technology to find a method for updating forest resource maps. [Method] VML technology was combined with recent and commonly used PHP and database technologies to produce a design scheme for a display system of forest resources in B/S mode. Data in this study came from the Caijiachuan forest farm of the Huanglongshan Forestry Bureau, Shaanxi Province. [Result] Through this study we were able to build a real-time system for displaying forest resource maps based on VML technology. The system was used to create a real-time forest resources map of the Caijiachuan forest farm. [Conclusion] The development of real-time system for displaying visual images of forest resources maps will provide users with more information so they can quickly and conveniently make decisions.
