基于AJAX的Internet地图服务方法初探

2005年,AJAX技术被提出并开始成熟,已经迅速走向实际应用。短短1年间,基于AJAX技术的Intenet地图服务如雨后春笋般涌起,如Google Maps、百度地图、搜狗地图、Yahoo Maps和MSN Virtual Earth等。本文首先分析了Intetnet地图服务现状——人们对地图服务需求迫切和地图服务不够快速友好的矛盾,并简单介绍了AJAX技术及其优点,在此基础上,初步探讨了基于AJAX的Internet地图服务方法的相关原理,给出了地图服务框架,并简单讨论了地图服务AJAX引擎包含的若干对象,最后分析了其优势和前景,并对地理信息服务的发展方向进行了思考。

A new research of Internet mapping service based on AJAX

Internet Mapping Service has been an important part of the lives of most countries, governments, companies and people, thus it is also an important area in science researches. Being proposed in 2005, the technology of AJAX has become more and more mature, and quickly comes to the practical application. After one year's development, various internet mapping service based on AJAX has been widely used, such as Google Maps, Baidu Maps, Sogou Maps, Yahoo Maps and MSN Virtual Earth. This paper firstly analyzes the current situation of internet map services: there are conflicts between the immediate commands for map services of people and the slow and unfriendly map services. Then it simply introduces the advantages of AJAX. Further more, it explores some principles of the Internet Mapping Service based on AJAX, provides the framework of new mapping services, and discusses the objects of AJAX Engine. In the end, it analyzes the predomination and prospect and thinks about the direction of Geographical Information Service.
