简介：真颜色图象城市地图是联合高分辨率图象和地图符号并且在可视化显示出两个优点的一种新式的地图。同时，地图统一和调和化应该在设计过程期间被考虑，自从当地图符号在真颜色图象上覆盖了时，一些视觉冲突出现。这研究的目的是在真颜色图象城市地图设计的进程探索规则基于色彩并且美学知识。在结束，作为设计问题的一个例子，图象颜色调整，道路网络演讲，和符号拿广州的图象地图集将在应用程序被讨论。

简介：根据各种各样的算法的分析，称为刷子方法的一个抗混叠算法被介绍，它是合适的印射出版标志。在详细介绍刷子方法的基本原则和实现以后，结果和效率通过实验被评估。

简介：排水量操作员是一重要、静止在地图归纳的一个热话题。在归纳产品，符号一定不含糊、容易察觉、容易地听说，它在特征之中做空格竞争在地图的进程的一个重要障碍反对排水量。通过繁殖过程，在目标之间的空间冲突可以被散布，更多的目标可以漂流进它。为了维持符号，在符号的对象，一些不重要的符号或部分之间的平衡和空间关系应该根据视觉图形的分辨率阀值在限制下面被弄歪在地图特征之中弄明白空格竞争。包括位置，易读性和特征的三限制为符号平衡和空间关系的维护是重要的，它在这篇论文被讨论。骨骼被介绍表示区域目标考虑特征，一个区域目标能在被分开到在构造根据他们的重要性分开教主的联盟者。然后，有限元素方法被用于地图目标的排水量和失真，为有限元素方法的参数的策略在被讨论。

简介：地图数据显示是在嵌入的即时航行下面的基本信息表示模式。在有几种尺寸和相应数学描述公式的航行显示器数据集(NDIS_SET)被设计以后，一系列规则和算法被推进优化嵌入的航行数据并且支持数据索引和输入效率。在一个正常航行数据显示算法说出NDIS，相关问题被分析以后，有数据说出N_PDIS的航行的一个新平行显示器算法然后被介绍适应计算和存储器的有限嵌入的资源。N_PDIS能同时地由二个平行线程创造二张准备位图并且交换他们之一自动地屏蔽。与NDIS相比，结果证明N_PDIS在改进显示效率是更有效的。
