摘要
针对全息地图是全息技术应用于地图学领域而产生的一种全新的概念、模型和产品,目前全息地图在概念、表现形式、产品模式等方面还没有明确的、一致认可的结论和体系,其解决方案尚有待研究的状况,该文提出了全息地图及其多重表达的方法和模式。首先建立全息地图三维嵌套(即1个大三维嵌套3个小三维)语义模型,进而研究在数学模型和自适应机制驱动下的LOD对比和对象滑动/切换等系列化展示的全息地图多重表达方法,以及自然语言、图形、图像与场景相结合的全息地图多重表达技术手段,实现先分解和降维、后聚合和升维的全息地图多重表达实现策略。希望能够起到抛砖引玉的作用,也期盼广泛开展全息地图方向的合作研究。
Holographic map is a completely new concept,model and product brought about after holographic technology was applied in cartography,and represents high-end academic tendency of the discipline.Since there is no unified definition,accurate systematic description,obvious product mode and solution on holographic map,therefore this paper set forth the method of modeling and multiple-representation（MR）of it.Firstly,a semantic model of Hierarchical Nested 3 Dfor holographic map was raised,i.e.,three sub-3 D models are nested within a master 3 D model.Secondly,the MR method of holographic map was related,i.e.LOD,geographic object sliding and switching based on mathematic model and self-adaptive mechanism.Thirdly,the MR technologies of holographic map was researched,i.e.the integration of natural language,graphics,images and scene.Finally,the implementation strategy of MR of holographic map was concluded,i.e.,to decompose the geographic objects and phenomena in the first step,which realizes MR in reduced dimension way,and then aggregate the objects,so realizes MR in increased dimension way.We hope to lead discussion and cooperation on holographic map.
