摘 要: 对网络电子地图的自适应可视化机制进行了研究,建立了自适应地图可视化系统的自适应用户模型、自适应的数据组织和自适应结构。试验系统主要根据"用图目的"对用户进行划分,建立用户模型;利用地图瓦片技术和背景与热点集成技术,实现了地图瓦片的自适应数据组织以及用户模型支持下的地图自适应可视化等基本功能。 In this paper, the adaptive visualization mechanism of network electronic map was studied,and adaptive user model,adaptive data organization and adaptive construction was built based on adaptive map visualization system. According to "the purpose of using map", four types of user model were provided in the experimental system. Using map tiles and the integration technology of context and hot information, the fundamental functions such as data organization of map tiles, map adaptive visualization supported by user model were realized.
