面向数据服务与计算服务的林业空间信息网格技术

Forest spatial information grid technology oriented data service and calculation service

目前林业信息系统资源共享程度低,协同工作能力差,所采用的软件体系结构所存在缺陷。在遵循信息集成技术和森林资源管理的最新发展趋势的基础上,将网格技术引入林业信息系统中,在不改变原始数据的存储和管理方式下,综合运用GML、SVG、Web服务、网格等技术,利用GML进行空间数据集成,使用Web Service提供服务,运用SVG实现空间数据可视化,构建起林业空间信息网格平台(FSIG)。该平台能改善空间数据共享和应用的环境,实现林业资源信息全面共享和信息系统集成一体化管理,提高系统内资源的协同工作能力,满足日益增长的对林业空间信息多层次、多样化应用的需求。

The current forestry information resources system is a lower resources sharing level,the cooperative work ability is poor,and the software structure of the system has some deficiencies.On the basis of abiding the latest integration of information technology and the forest resources management,the grid technology was introduced into the forestry information system.Without any change in the original data storage and management mode,comprehensively adopting GML,SVG,Web services,the grid technology etc,the space data was integrated,Web service was available,and the space data visualization was realized by SVG,thus the forestry spatial information grid platform（FSIG） was to constructed.This platform can improve the spatial data sharing and applying environment,realize forestry resources information sharing,arise comprehensive integrated management information system integration,and improve the resources cooperative work ability inside the system,and meet the increasing of forestry multi-level and diversification of spatial information application requirements.
