Description: 最短路径算法源码，很多人需要的。本人载网站开发gis,游自编的最短路径查询程序，速度特快，3万节点，35000条路全部遍历，只需1秒。现将最短路径的思路告诉大家，希望大家在优化，并用不同语言编制，我正在学delphi,准备用delphi做成库，本例以由拓扑关系的arc/info 文件为数据源。其中a1,b1,c1是以fnode排序生成的数组，a1对应fnode,b1对应tnode,c1对应length,同样a2,b2,c2,是以tnode 生成的数组。Indexa1是对应某一起点与其相连的终点的个数，indexb1时对应某一终点与其相连的起点的个数，即其拓扑关系。
-shortest path algorithm source, a lot of people in need. I gis contained web site development, Yu directed the shortest path query procedures, speed express routes, 30,000 nodes, all 35,000 traverse the road, only a seconds. Now Shortest Path tell you the idea that we should optimization, and use different language, delphi is studying, I wanted to use delphi caused basement, in the cases from the arc topology / info file as the data source. Which a1, b1, c1 fnode ranking is generated by the array, a1 fnode counterparts, b1 counterparts tnode, c1 corresponding length, the same a2, b2, c2, tnode is generating array. Indexa1 counterparts is a starting point, linked with the end of the number, indexb1 counterparts at a terminal connected to its starting point the number, which is its topologic

Description: 随着Web平台越来越成熟，我们可以发现有越来越多的令人兴奋的技术出现，这些技术使地理信息系统(GIS)的显示应用达到了一个功能强大且应用广泛的新高度，通过把最新的功能强大的技术整合到GIS系统中去，我们得到了高效率执行的结果，随之赋予了更多的功能。在目前基于浏览器应用程序的开发技术中，AJAX(Asynchronous JavaScript and XML)无疑是最新的技术。在本文中，我们介绍了一个通用的，高效的架构，这个架构把AJAX模型整合到了GIS Web Services显示系统中。-With Web platform matures, we find more and more exciting technology that These technologies enable geographic information system (GIS) to show that a powerful and widespread use of new high through the latest powerful GIS technology to integrate systems, and we have a highly efficient implementation of the results, attendant given more functions. Based on the current browser application development technologies, AJAX (Asynchronous JavaScript and XML) is the latest technology. In this paper, we introduce a common and efficient structure, The framework put AJAX model of integration of GIS Web Services Display System.

Description: MapEasy is a web mapping client api which has an alogy with Google Map Api. It helps to build a map-based application easily.
Based on Javascript and AJAX technology, MapEasy will work on most modern browsers (Firefox 1.0+, Internet Explorer 6.0+) using simple Javascript calls. Independent from the concrete GIS technology and specification, MapEasy allows you to request maps as rendered images (normally JPEG,PNG or GIF), and fufills the normal GIS functions such as locating, zooming, and marking...
Key Features:
open source
pure javascript application
easy to use
API is similar to google map api
decouple the map view and the data service. independant from the specifical map data service
self define Plane Coordinate system(not available yet)
customisable and easy to extend
support IE6, Firefox/Mozilla, Opera(not available on Opera yet)
support Latitude/Longitude Coordinate System
