Generalized fuzzy logic and lock semantic resolution principle 广义模糊逻辑和锁语义归结原理
The article brings forward a kind of distributed and generalized spatial data engine ( SDE) expressed by semantic object models, based on the resolution of GML criterion and the frontier research of spatial data engine. 在解析GML规范与空间数据引擎前沿研究成果的基础上,提出了一种语义对象模式表达的分布式广义空间数据引擎(SDE)模型。
