| Abstract: |
| 【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 |
