【摘要】 空间数据可视化是当前地图学研究的重点与热点,论文系统分析了当前空间数据可视化输出的发展现状,提出研究空间数据跨媒介可视化输出的必要性与可行性,并详细分析了出版地图可视化输出、电子地图可视化输出与网络地图可视化输出的特点,提出空间数据跨媒介可视化输出的研究方法。当前大部分空间数据可视化软件系统大都侧重于某一种或两种媒介的可视化输出,对于跨媒介可视化输出表达的一致性与统一性研究的比较少。本文对此进行深入分析,重点研究和解决空间数据跨媒介可视化输出中符号库与符号化、注记表达、色彩管理等方面的关键技术,实现空间数据跨媒介可视化输出效果的一致与统一。主要内容如下:1、空间数据跨媒介可视化输出相关理论与技术研究。从科学计算可视化以及空间数据可视化的发展历史、处理过程以及研究内容入手,研究空间数据跨媒介可视化输出的理论基础,分析空间数据在不同媒介上可视化输出的特点,提出跨媒介可视化输出的研究方法。2、支持跨媒介可视化输出的地图符号库与符号化研究。地图符号库的设计及符号化技术是实现空间数据跨媒介可视化输出的关键技术,从某种意义来说,空间数据的跨媒介可视化输出实质上就是地图符号的跨媒介可视化输出,本文在介绍地图符号的相关理论研究发展与不同媒介绘图语言特点的基础上,分别给出了支持跨媒介可视化输出的点状符号、线状符号以及面状符号的描述与设计。此外,符号化效果决定着空间数据表达的准确性,本章分析了当前主要的三种符号化控制方式,并提出了一种基于关系数据库的符号化预处理方式,既能保证符号化的准确性,又不影响地图显示的速度。3、空间数据跨媒介可视化输出中的注记表达。地图注记的表达是空间数据跨媒介可视化输出非常重要的一个环节,直接关系到可视化输出的效果,本文主要介绍了地图注记的设计、注记的存储(重点的说明注记的存储),字库的选择以及注记的绘制,为空间数据跨媒介可视化输出中注记的表达给出了可行的思路。4、空间数据跨媒介可视化输出色彩管理。不同的媒介中支持的色空间以及表色能力各不相同,因此保持色彩在不同媒介中的准确传输是实现空间数据跨媒介可视化输出一致性的重要条件,论文在详细分析三种色彩管理模式的基础上,给出了跨媒介可视化输出中实现色彩管理的思路和方法:ICC颜色管理与SRGB标准相结合的方法来进行色彩管理。最后,在空间数据跨媒介可视化输出关键技术研究的基础上,论文设计了空间数据跨媒介可视化输出原型系统,主要包括系统结构的设计、系统平台的选择,最后介绍了原型系统的功能与界面。更多还原

【Abstract】 The thesis analyzed the current development of spatial data visualization on the whole and indicated the necessary of research on multi-medium outputting of spatial data, and then introduced three main outputting methods, including publishing map outputting, electronic map outputting and web map outputting in detail. At present, most softwares about visualization of spatial data only emphasize one or two outputting mediums. There are few researches about coherence and unification of multi-medium outputting of spatial data. To realise this aim, this thesis made a deeply study on the pivotal technology including map symbol library and map symbolization, color management and annotation represent about multi-medium outputting of spatial data. The main content and results of this research are as following:1. The research of interrelated theories and technique.The thesis start with the developping course, managing process and studying content of visualization in scientific computing and visualization of spatial data. Then through studying the mainly theories on multi-mediums visualized outputting of spatial data and analyzing the characters of different medium visualized outputting, the thesis put forward the research way of multi-mediums visualized outputting.2. Constructing map symbol library and symbolization.Constructing map symbol library and symbolization are very important for multi-medium outputting of spatial data. Based on presentation of interrelated theories about map symbol and each graphical interface, the article put forward the design and description of dot symbol, line symbol and area symbol which support multi-medium outputting. And through analyzing current map symbolization technique, this article brought forward a pretreatment symbolization way based on RDS.3. Expression of annotation.Expression of annotation is an important aspect of multi-medium outputting of spatial data. It affects the result of multi-medium outputting of spatial data. The article mainly presents the design of annotation, the configuring of annotation, the select of letter library and the display of annotation. It puts forward a feasible way of expression of annotation in multi-medium outputting of spatial data.4. Color management.Keeping exact transmission of color is very important to ensure the coherence of multi-medium outputting of spatial data. This article analyzed the current main color management means, and then put forward the color management method in multi-medium outputting of spatial data. This way integrated the ICC color management and sRGB color space.Basing on the research of the pivotal technologies, the article designed the archetypal system about multi-medium outputting of spatial data. It mainly includes the design of structure of system, the select of basal system. At last the article introduced the functions and interfaces of archetypal system.更多还原
