【摘要】：现代地图学正处于信息化地图学发展与转变过程之中,其强调以地理信息服务为核心并集数据获取、处理、功能服务一体化,是对传统地图学与数字化地图的深化与超越。其中,专题地图作为地图学的一个重要分支,也朝着信息化的方向发展,在各行各业也得到进一步的应用和扩展。目前,专题地图的应用呈现出大众化发展趋势,但当前普通大众缺少专业制图知识与专业制图软件专业性强这一矛盾使大众制作专题地图存在困难。因此本文在深入分析了当前在线专题制图产品存在的不足之处的基础上,依据制图即服务‖这一概念,并对相关制图理论、可视化技术、制图模式和流程进行探讨,最后,基于NewMap Server软件提出了一套集在线专题制图服务(Web Service)和前端专题制图API为一体的解决方案,并在此基础上设计并实现了面向服务的在线专题制图系统。本文的主要研究内容如下:(1)分析了现有的在线专题制图相关理论方法,对比了专题图制图模式和前端可视化技术,提出一种合适的在线专题制图技术方案和制图流程。(2)基于NewMap Server架构,设计并实现在线专题制图服务,并对在线专题制图服务的运行机制以及服务方法的调用、返回信息等内容进行详细的说明。(3)为完成对在线专题数据的处理需求,提出了对空间坐标数据的编码解码方法以及对专题数据的分级处理方法。(4)实现对专题数据的可视化,基于ECharts类库以及Canvas特性实现对九大类专题制图接口的封装,完成专题数据的可视化。(5)对在线专题制图原型系统进行设计研发,完成专题数据上传、服务调用、专题符号在线可视化的一体化应用。
[Abstract]:Modern cartography is in the process of development and transformation of information cartography, which emphasizes the integration of data acquisition, processing and function service, which is the deepening and surpassing of traditional cartography and digital map.Among them, as an important branch of cartography, thematic map is also developing towards the direction of information, and has been further applied and expanded in various industries.At present, the application of thematic maps shows a trend of popularization, but the contradiction between the general public's lack of professional cartographic knowledge and professional cartographic software makes it difficult for the masses to make thematic maps.Therefore, based on the deep analysis of the shortcomings of online thematic cartography products and the concept of cartography as a service, this paper discusses the related cartographic theory, visualization technology, cartographic model and process.Based on NewMap Server software, this paper presents a solution which integrates online thematic cartography service and front-end thematic cartography API, and then designs and implements a service-oriented online thematic cartographic system.The main research contents of this paper are as follows: (1) analyzing the related theories and methods of online thematic cartography, comparing the pattern of thematic cartography and the front-end visualization technology.This paper puts forward a suitable online thematic cartography technical scheme and cartographic flow. It designs and implements the online thematic cartographic service based on NewMap Server architecture, and calls the running mechanism and service method of the online thematic cartographic service.In order to complete the processing requirements of online thematic data, a method of encoding and decoding spatial coordinate data and a method of hierarchical processing of thematic data are proposed to realize the visualization of thematic data.Based on ECharts class library and Canvas feature, we can encapsulate nine kinds of thematic cartographic interface, complete the visualization of thematic data, design and develop the online thematic cartographic prototype system, upload the thematic data, and call the service.Integrated application of online visualization of thematic symbols.
