As far as web gis is concerned , xml can be used in standard storage for spatial data , data sharing , network transmission , electric map displaying and gis software framework building 对于webgis而言， xml相关技术可以用于地理空间数据的规范化存储、地理数据共享、网络传输、电子地图显示和gis软件体系架构的建立等。
In the current times of information and digital earth , the content of geo - spatial data is complicated and its quantity is enormous . it is practical and feasible method to set up the geo - spatial metadata for managing and sharing the data 在当今信息化与数字地球时代，地理空间数据内容繁杂且数据量庞大，建立地理空间数据元数据是对其进行管理及共享的有效、可行的方法。
Webgis i s a new technology which using the internet technology to expend and consummate the geography information system . man can use it to find the geography spatial d ata , picture and image they need , and also can use it to do some geographical sp atial analysis Webgis是利用互联网技术来扩展和完善地理信息系统的一项新技术，人们可以利用它寻找他们所需要的各种地理空间数据、图形和图像，而且可以进行地理空间分析。
At present , geospatial data can be encoding into svg format . but it is not properly resolved that how to dynamic publish svg graphics from the spatial management engineer , realize the complex spatial analysis of svg vector graphics and the svg edit function of webgis 目前,可以将地理空间数据编码成svg格式,但是如何基于空间数据管理产品动态发布svg格式的矢量地图,以及在此矢量地图上实现复杂空间分析和图形编辑,一直没有得到很好的解决。
It is emergency for us to explore how to use world wide web as the distributed computing platform for gis , how to release geographic space data and information in the internet and how to make it easy for users to search the geographical information which was needed in the internet 我们迫切需要解决如何以国际互联网作为分布式计算平台构建地理信息系统，如何在国际互联网上发布地理空间数据和信息，如何方便用户查询所需要的相关地理信息等问题。
The forest fire size class forecasting may success through many times practices if the atmosphere circulating current index and fire index are known . in the web , subscribers may forecast the class of the forest fire size using the program in the local database and get the interesting regional view which is shown by the gis software 本文实现了在提供地理空间数据的本地数据库的森林火险的预测，在基于网络环境下，用户可以在预测程序中得到森林火险的等级，并能使得地理软件显示出要预测地区的森林火险的视图。
This lecture is about introduction of geographic information system concept and context ; geographic data concepts ; how to start your gis project ; how to get spatial data ; how to make spatial data usable ; how to get attribute data ; how to manage gis database ; how to perform geographic analysis ; how to present the results of the analysis and so on 地理信息系统课程内容主要包括：地理信息系统的基本概念、原理；地理空间数据概念；如何实施一项地理信息工程；如何获取空间地理数据；如何保障空间数据的可用性；如何获得属性数据；如何管理空间和相应的属性数据，建立空间数据库；如何进行与地学等学科专业有关的空间分析；如何评价空间分析结果等内容。
The research work is done for such problems as spatial data storage , network transmission , data sharing and interoperation in web gis research and exploitation . the primary research target is to establish a web service system for geographic data issue based on svg , gml and soap / web service technologies , and to establish a cgi - based web gis service system 本文针对webgis的研究和开发中，有关地理空间数据的存储，网络传输，数据共享和互操作等方面存在的问题展开研究，研究的主要目标是基于svg 、 gml和soap / webservice技术建立地理数据的web发布服务系统，设计并实现了webgis的地理信息服务系统。
In the end , we introduce the plan choose oracle and microstation geographics to explore the gis application system . through the realization details discussion of management and application about spatial data , we provide a useful mechanism to manage the geographic spatial data , and successfully realize the gis of chongqing fire control 最后介绍了利用oracle和microstationgeographics来开发gis应用系统的解决方案，对有关空间数据的管理和应用的实现细节进行了讨论，提出了一个有效地管理地理空间数据的机制，并成功的实现了重庆消防gis应用系统。
Now the research on spatial geo - data sharing and cooperation focuses on integrations of model as well as software technology . however , not only the mind but also the methods in gis integration are quite bitty , far from general . so we need to unify , both in micro and macro points of view , the framework of theory and method in various aspects of gis system 当前对地理空间数据共享与互操作的研究主要集中在模型集成和软件技术集成方面，但是gis集成的思想和方法还比较支离破碎，不够全面，因此有必要从微观和宏观的角度入手，通过gis系统各个不同的视角，统一gis集成的理论和方法体系，形成一个统一的框架。
