一个基于SVG的空间分析技术的研究

Study of Spatial Analysis Technology Based on SVG

SVG是互联网联盟(W3C)的正式推荐标准。如何在SVG格式的矢量地图中,实现复杂空间分析,是一个有待研究的问题,借助空间数据管理产品实现SVG图形的空间分析,是一个很好的解决方案。该方案解决的核心问题,是如何实现SVG和空间数据管理产品定义的空间数据类型的相互转换,就此对SVG和Oracle Spatial的空间数据的表达方式做了深入的分析,并给出了具体的转换流程和空间分析的实现过程。

SVG is W3C Recommendation Specification. It is not properly resolved that how to realize the complex spatial analysis of SVG vector graphics. It is a good scheme to resolve the problem based on spatial data management products. The core problem is how to realize the two-way conversion between SVG and data type of spatial data management products. This paper analysises deeply the spatial data expression way of SVG and Oracle Spatial, at the same time give the conversion process and spatial analysis process i...
