【摘要】：在分析当前网络地图出版特别是专题地图网络出版现状的基础上,本文提出了版式网络地图的概念、原理及技术方法。版式网络地图克服了当前专题地图出版GIS化和静态图片化的倾向,在为用户提供高保真地图阅读体验的同时,实现了专题数据和专题地图同时发布的模式。该模式的主要技术特点包括:对专题地图图片和专题地图数据进行四叉树分解,将专题地图图片划分为规则格网大小的瓦片金字塔;将专题数据要素分解为可变分辨率的格网集合,以唯一标识记录每个格网及其(需查询的)属性,并采用支持区域、时间、指标、数据四元组的专题数据元进行存储,以便高效地索引专题数据,从而实现专题地图数据的高效查询。同时,本文还介绍了版式网络地图发布模式在地形图出版、原图版式发布、《中华人民共和国人口与环境变迁地图集》电子版网络地图发布系统中的应用案例。最后,对比分析了Web GIS、静态地图图片、PDF/Geo PDF地图、SVG地图以及版式网络地图5种发布模式的优缺点,结果表明版式网络地图是一种有望在专题地图出版领域推广和应用的轻量级地图发布模式。
[Abstract]:On the basis of analyzing the current situation of network map publishing, especially the special topic map, this paper puts forward the concept, principle and technical method of layout network map. The layout network map overcomes the current tendency of publishing GIS and static picture of thematic map. It provides users with the reading experience of high fidelity map and realizes the mode of both thematic data and thematic map being released at the same time. The main technical features of the model include: the thematic map image and thematic map data are decomposed into quadtree, the thematic map image is divided into regular grid size tile pyramid; The thematic data elements are decomposed into a grid set with variable resolution, each grid and its attributes are recorded by unique identification, and the thematic data elements of support region, time, index and data quaternion are used for storage. In order to efficiently index the thematic data, and realize the efficient query of thematic map data. At the same time, this paper also introduces the application cases of the publishing mode of the layout network map in the topographic map publishing, the original map layout publication, the people's Republic of China atlas of population and environmental change, the electronic version of the network map publication system. Finally, the advantages and disadvantages of five publishing modes of Web GIS, still map picture and PDF / Geo PDF map and layout map are compared and analyzed. The results show that the layout network map is a kind of lightweight map publishing mode which is expected to be popularized and applied in the field of thematic map publishing.
