摘要
根据林业信息系统数据特点,在不改变原始数据的存储和管理方式下,提出一种基于WebSer-vice的异构数据集成模型,利用GML进行空间数据集成,使用SVG实现空间数据可视化,建立GML&SVG的WebGIS应用模型,该模型能较好地实现异构数据源统一、透明的访问,保证数据的完整性、安全性和一致性,为林业多源异构空间数据的集成提供解决方案,有效地实现林业信息异构数据的共享。
In this paper,a model of spatial data integration of multi-source heterogeneous data based on WebService was established,according to the characteristics of forestry information system and without changing the original data storage and management mode. The GML＆SVG WebGIS application model which using GML for spatial data integration and using SVG for visualization of spatial data. The model can realize heterogeneous data sources unified and transparent access, ensure data integrity, security and consistency, which provided a solution that could effectively achieve the Forestry Information heterogeneous data sharing.
