手持设备自身的限制及无线网络环境的特点，要求地图在许多方面进行改革以适应新的技术条件。制图综合作为地图生产与制作的重要环节，是当前移动环境下地图应用必须面临的问题。本文以居民地综合算法为例，探讨了部分算法在移动环境中的执行效率，并进行了可用性验证。尝试将移动环境中用户位置以及用户的当前任务等上下文信息用于综合算法中，设计以用户位置及当前任务为中心的实时制图综合算法，最后以案例证明了算法的可用性。 |

The restrictions of hand-held devices and the characteristics of wireless network environment require improvement of the map to adapt to the new conditions. As an important tache in the process of map production, map generalization is the challenge we have to face in the moible environment. In this paper we probe into the efficiency of part of generalization algorithms on settlements, and test the usability of them. We also attempted to design the algorithm on settlement which takes the user＇s context into account, including user＇s task, user＇s location etc. Finally we proved the usability of the algorithm based on the given case. |
