| 中文摘要: |
| 针对移动位置服务系统对空间信息多尺度组织和管理技术的迫切需求，系统探讨了位置服务中的空间信息多尺度表达、传输、发布和自适应可视化技术的研究问题，重点评述了国内外研究现状、进展及存在的主要问题，指出了未来研究的重点，以及发展针对移动位置服务特点的信息组织技术，解决矢量数据的多尺度表达及其在数据库中的分级分块组织，减缓地理空间信息量大、无线带宽较窄和移动资源有限之间的矛盾，实现移动位置服务的个性化和智能化的研究方向。 |
| 英文摘要: |
| According to the developing need of multi-scale spatial data organization and management of mobile location service systems, this paper reviewes in detail the main research developments of multi-scale spatial data organization in the fields of representation, transmission and adaptive visualization. Then it generalizes the key techniques and existing problems in the fields. This follows the analyses of the unsolved problems corresponding to the above fields. And at last, it predicts the focal points of the research and points out the major research direction on developing multi-scale spatial data organization technology with mobile location service characteristics, and solving the multi-scale representation of vector data and its hierarchical block organization in the database, as well as slowing the contradictions among the large amount of spatial data, the narrow wireless bandwidth and limited mobile resource to provide with personalized and intelligent mobile location services. |
