Less than 100 , 000 of greece ' s four million coastal people have sewage properly treated and greece , as our map shows , is one of the cleaner countries of the northern shore 在希腊四百万沿海居民中仅有不足十万人适当处理了其生活污水，而据我们的地图显示，希腊还是地中海北岸比较干净的国家之一。
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。
" the maps show , very strikingly , that a large part of our planet ( roughly 40 % ) is being used for either growing crops or grazing cattle , " said dr navin ramankutty , a member of the wisconsin - madison team 地图显示，非常显著地，我们星球的一大部分（约40 % ）被用来种植作物或放牧，威斯康辛-麦迪逊团队一员的的纳文?拉曼克提表示。
Powercommap is a component gis platform , composed with an activex and a serial of automations . it is easy for users to add gis and mapping function to any . system that based on microsoft windows system 使用powercommap ，二次开发人员可以利用任何符合工业标准的windows编程环境，按照用户的特定需求，定制或在任何应用系统中嵌入地图显示和gis功能。
However , the most recent changes to the county boundary that are not shown ( berkshire , buckinghamshire and surrey county boundaries orders of 1991 and 1994 ) leave a certain fog over that small portion of the county to the north 但是，没有在这个地图显示的最近一次郡界改动（根据《 1991年及1994年伯克夏郡、白金汉郡及萨里郡郡界法令》 ） ，使得泰晤士河河北的一小片郡域变得相当模糊。
Because of its strong spatial query function and its support for various client platforms , we chose arcims as the webgis platform . the system uses the popular asp ( active server page ) method and the most - used webgis software - arcims to generate , release and transfer the disaster information 3 、对国外多个基于web的地图应用系统(国外有代表性的webgis网站)的浏览功能、使用方法、地图显示、功能、交互性、定制功能、特殊功能等几个方面做了比较。
Then it sets up the way that carry out map showing in embedded condition , landform analyzing and gps data receiving . in the end , the foreground is analyzed and the points that need to improve is brought forward 论文首先分析嵌入式地理信息系统的研究现状、技术背景、特点及应用，为嵌入式地理信息系统( egis )的开发提供技术基础；其次提出了实现egis中的嵌入式平台环境下的地图显示、地形分析和gps数据接收的方法；最后分析了系统的应用前景和需要改进的地方。
In the third part of this paper , the map display model , data structure , map symbol library , and system function of the map display system are designed with the direction of cbd theory ; and finally , the map display objects classes are worked out with oo technology 第三部分运用软件工程的设计思路，以组件式软件设计思想为指导，设计了地图显示系统的框架模型、数据结构、地图符号库和系统功能，并在此基础上，利用面向对象的技术和方法设计了地图显示对象类。
This system integrated the gps ( global position system ) , gis ( geographic information system ) , gsm ( global system for mobile ) , graph theory , the technology of computer network and so on . it has the function of displaying electronic map and vehicle real - time monitoring , vehicle alarm processing , the optimization of the shortest path and so on . it can monitor and manage the vehicles remotly effectively which is important for the vehicle keeping the security ; it can also improve the vehicle running benefits , alleviate the traffic hustle and jam through the shortest path optimization 该系统综合了全球卫星定位系统( gps ) 、全球移动通讯系统( gsm ) 、地理信息系统( gis ) 、图论、计算机网络技术于一体，可实现电子地图显示、车辆实时监控、车辆报警处理、车辆最短路径选择等功能，能有效的实现对车辆的远程监控和管理，对保障车辆的安全有重要作用；通过选择最短路径可以提高车辆的运营效率、缓解交通拥挤和阻塞。
After analyzing the advantage and disadvantage of some models ( such as cgi server apk plug - i activex java applet ) in constructing webgis , the paper analyzes the system characteristics and some application branches of a perfect net language - java , so all of this give prominence to the advantage of applying java in constructing webgis . then in view of software engineering the paper analyzes the superiority of developing component - based webgis by javabeans and practices the yunnan resort navigation system using maplnfo " s mapxtreme for java 3 . 1 beans . the system can provide some basal functions such as zoom in , zoom out , pan , adding theme , measuring and so on 接着论文分析了构造webgis的几种模式? ? cgi模式、服务器应用程序接口方法、 plug - in模式、 activex模式以及javaapplet模式的优缺点，进而阐述了网络语言java的系统特性及其各种应用分支，突出了采用java开发webgis的优势，然后从软件工程的角度分析了采用javabeans进行webgis组件式开发的优势，并具体试验了基于mapinfo公司mapxtremeforjava系列beans进行云南省旅游景点导航系统的构造，开发出的系统实现了地图显示、放大、缩小、漫游、添加专题等常规的gis功能。
