【摘要】：地理信息系统,即GIS,作为一门有着40多年发展历史的技术,从架构方式上来说分为两种：基于组件和基于服务,传统的GIS开发方式都是基于组件的架构,也就是说,利用各种编程语言实现一个独立的功能模块,多个简单的模块组成一个复杂的功能系统,随着时代的发展,这种方式的弊端越来越突出,如平台依赖严重、开发成本高、数据维护不方便等等。Web2.0的发展正好为GIS提供了更新换代的契机,一种新型的面向服务的WebGIS架构REST应时而出。论文首先对比了两种面向服务的GIS架构方式：基于SOAP和基于REST, REST方式以高度的灵活性和易用性,更好的缓存支持,更容易检索和发现,成为未来的发展趋势。物联网一词最早在1999年提出,经过短短的十几年,已经广泛地应用在国计民生的方方面面。本系统正是综合运用了GIS技术和物联网技术的信息管理系统,既有GIS地图简洁直观的展现方式,又具有物联网强大的信息收集处理能力。然后论文详细说明了系统的总体设计、整体需求和功能设计。接着系统最终使用基于ArcGIS Server这一平台进行实现,因为／ArcGIS Server拥有强大的REST API可以方便的进行开发。最后论文论述了系统特色和不足,同时说明了后续工作如何开展,对于地理信息系统和物联网的研究有一定的借鉴意义。
[Abstract]:Geographic Information system (GIS), as a technology with a history of more than 40 years, can be divided into two types in terms of architecture: component-based and service-based, and traditional GIS development is based on component-based architecture. Using various programming languages to realize an independent functional module and many simple modules to form a complex functional system, with the development of the times, the disadvantages of this way are more and more prominent, such as platform dependence, high development cost, The development of Web 2.0, such as inconvenient data maintenance, provides an opportunity for GIS to be updated, and a new service-oriented WebGIS architecture, REST, comes out in time. This paper first compares two service-oriented GIS architectures: based on SOAP and rest, REST with high flexibility and ease of use, better cache support, easier retrieval and discovery. The term "Internet of things" was first proposed in 1999, and has been widely used in all aspects of the national economy and people's livelihood after a short period of ten years. This system is an information management system that integrates GIS technology and Internet of things technology. There are not only the simple and visual display of GIS map, but also the powerful information collection and processing ability of the Internet of things. Then the paper explains the overall design, the overall requirement and the function design of the system in detail. Then the system is implemented on the platform of ArcGIS Server, because the REST API can be developed easily. Finally, the paper discusses the characteristics and shortcomings of the system, and explains how to carry out the follow-up work, which has a certain reference significance for the study of GIS and Internet of things.
