Description: 数据库连接在WebGIS开发中的应用颇为频繁．而由于多用户并发操作以及网络软硬件条件等方面的影响，连接的速度往往不尽如人意。文中利用JDBC技术．在WebGIS中设计并实现了基于Oracle数据库和Java AppJet／ServJet网络模式的数据库连接池，从而大大提高了数据库连接的效率，同时还可以通过连接池自身的管理机制来监视数据库连接的数量和使用情况。-Database connection in WebGIS application development rather frequently. And as multi-user concurrency, and network hardware and software conditions, and other effects, the connection speed is often unsatisfactory. The paper uses the JDBC technology. Designed and implemented in WebGIS based on Oracle database and Java AppJet/ServJet network model database connection pool, thus greatly improving the efficiency of database connection, but also by its own connection pool management mechanism to monitor the number of database connection and use of .

Description: 目前空间数据的传输效率低下已成为制约WebGIS发展的主要瓶颈之一。多线程技术以及多点连接在提高系统吞吐率、有效利用系统资源、改善用户任务之间的通信效率等方面有着显著作用。本文采用地图分层和图面分割的方法以及Java多线程和多点连接技术实现了WebGIS空间数据的高效传输。-Transmission of the current inefficient spatial data has become a major bottleneck restricting the development of WebGIS. Multithreaded technology and multi-point connections to improve system throughput, efficient use of system resources and improve the efficiency of communication between the user and so the task has a significant effect. In this paper, the map layer and the segmentation method and the surface Java multi-threading and multi-point connection technology to achieve the efficient transmission of spatial data WebGIS.

Description: Google Maps之前，各种网络地图在技术上采用传统WebGIS 的方式，使用Java Applet、SVG、动态生成地图图片，客户每产生一次新的地图请求，服务器再重新生成地图图片发送至客户端。自从Google Map推出Tile Map Image（瓦片式地图）方式提供的地图位置服务之后，国内的go2map、mapabc、mapbar等专业地图搜索公司纷纷仿效，相继推出了基于地图瓦片金字塔模型的位置搜索新模式服务。-Before Google Maps, the map in a variety of network technologies using traditional WebGIS ways to use Java Applet, SVG, dynamically generated map image, the client generates a new map for each request, the server re-generate map images are sent to the client. Since the launch of Google Map Location Map Service Tile Map Image (tile map) provide the domestic go2map, mapabc, mapbar other professional map search companies have to follow, have launched a search for location-based map tile pyramid model of the new model services.
