【摘要】：互联网时代的到来,已经使得网络成为了人们日常生活、工作和学习中必不可少的一部分。在测绘行业中,利用网络技术来处理空间数据、共享地理信息的网络应用也越来越多,WebGIS随之而产生。网络地图的兴起,是Web技术与传统地理信息结合的伟大尝试,大大加深了人们对地理信息的认识。目前,各大网络地图公司发布的地理信息服务数据都是由本公司单方面提供的,用户只能被动地接受,缺乏主动式的地图专业解译制图功能,并且对影像的解译制图处理大都是通过桌面版的软件完成的。所以本文的目的是想利用Web技术,建立一个能够对本地的影像数据进行专业要素解译与标准制图处理的系统,用于数据的交换和信息的共享。本文根据面向服务架构SOA的原则对解译制图系统进行了设计与实现。系统采用B/S的设计模式,利用AJAX、Web Service、ASP.NET等技术对系统进行了集成。本文的主要工作如下。(1)研究了影像解译与标准制图的标准和规范,建立了支持该系统的解译符号库、整饰要素数据库和标注数据库。(2)研究了遥感影像上传的机制,为用户进行解译制图提供了数据基础。(3)研究了基于面向服务架构的模式中AJAX的原理,设计了影像解译流程,提供了影像解译接口。(4)研究了如何将Web Service技术与ArcObjects组件进行结合,并根据设计的制图流程,封装已有的C/S模式下的标准制图业务逻辑,并提供统一的制图接口。(5)设计并实现了解译制图的WebGIS系统,为用户提供了对影像数据进行解译与制图处理的网络平台。
[Abstract]:With the advent of the Internet era, the Internet has become an essential part of people's daily life, work and study. In the surveying and mapping industry, the use of network technology to deal with spatial data, the sharing of geographical information network applications are also more and more Web GIS followed by the emergence. The rise of network map is a great attempt to combine Web technology with traditional geographic information, which greatly deepens people's understanding of geographical information. At present, the geographic information service data released by the major web map companies are provided unilaterally by the company, and users can only accept them passively and lack the active mapping professional interpretation and mapping function. And the image interpretation and cartography processing is mostly done through the desktop version of the software. So the purpose of this paper is to use Web technology to set up a system which can interpret the professional elements of local image data and process the standard cartography, which can be used to exchange data and share information. According to the principle of Service oriented Architecture (SOA), this paper designs and implements a mapping system. The system adopts the design pattern of B / S and integrates the system with AJAX,Web Service,ASP.NET and other technologies. The main work of this paper is as follows: (1) the standards and specifications of image interpretation and standard cartography are studied, and the interpretation symbol database, decorating element database and annotation database supporting the system are established. (2) the mechanism of remote sensing image uploading is studied. It provides a data base for users to interpret cartography. (3) the principle of AJAX based on service-oriented architecture is studied, the image interpretation flow is designed, and the image interpretation interface is provided. (4) how to combine Web Service technology with ArcObjects component is studied. According to the designed drawing flow, it encapsulates the existing standard drawing business logic in C / S mode, and provides a unified drawing interface. (5) A WebGIS system for interpreting cartography is designed and implemented. It provides users with a network platform for image data interpretation and cartographic processing.
