中国主要的河流、湖泊地图，矢量(shp)格式(Map of main rivers and lakes in China, vector (SHP) format)

著名GIS平台 完整源代码 基于CGI的通过万维网来传输动态GIS与图像的应用程序(GIS platform for the famous full source code through the World Wide Web-based CGI to dynamic GIS and image transfer applications)

XYZ坐标转为GLOBK或者QOCA中的NEU，以及大地测量中大地线反解问题，即由经纬度解算大地线长度(convert XYZ coordinates into NEU in GLOBK or NEU, and geodetic earth line inverse solution, that solution by the latitude and longitude Geodetic Line length)

MapInfo的Tab文件转化为ArcGIS的Shape文件(MapInfo Tab files to ArcGIS Shape files)

说明：  测量基础软件开发。包括前方交会，后方交会，后方交会等个种测量的平差。(measurement based software development. Including forward intersection, the rear intersection, the rear other species fair measurement of adjustment.)

从下往上划出的效果demo，精选ios编程学习源码，很好的参考资料。(From the demo effect to draw on, select learning IOS programming source code, a good reference.)

常见的地图GIS二次开发有ARCGIS、MO、AO、MAPX、MapXtreme、ASPMAP，但是对于我们初接GPS/GIS项目的人来说，最头痛的问题是无法解决地图，调用GOOGLE的SDK就可以免费使用GOOGLE的免费地图资源，快速构建自己的GIS系统。这项技术可以应用于交通、运输、物流、安防、城市规划、城市管理、林业、农业、工业、灾难指挥、地震灾难等许多行业。采用这种方法应付毕业论文时最省事了，连数字化地图的步骤都省了，别人开发GIS系统要几个月，用GOOLE二次开发，只要短短的几天。我有一个学生，程序明明用GOOGLE的二次开发，但是在论文里大谈自己是用ARCGIS开发的，几个答辩老师愣是没瞧出来，这位学生，轻轻松松获得答辩高分。 本程序可以工作于vs.net各种版本，我编译时采用vs2008，asp.net采用3.5的支持库。(Common secondary development of GIS maps has ARCGIS, MO, AO, MAPX, MapXtreme, ASPMAP, but for us to pick beginning of GPS/GIS project for people who can not be solved the most headache problem is that maps, call the SDK can be free of charge GOOGLE GOOGLE maps using free resources to quickly build their own GIS system. This technology can be applied to traffic, transportation, logistics, security, urban planning, urban management, forestry, agriculture, industry, disaster command and earthquake disaster, and many other industries. When using this method to cope with dissertation The easy, and even the digital map of the steps are saved, others take a few months development of GIS systems, with GOOLE secondary development, as long as only a few days. I have a student, the program is clearly using GOOGLE secondary development, but the paper was much talk that he is using ARCGIS developed several defense teacher Leng Shimo Look out, the students, easy access to defense scores. This proc)

说明：  实现A*算法地图寻优路径问题，游戏地图采用网格地图。(Achieve A* algorithm maps the path optimization problem, the game map using a grid map.)

CSharp +SVG 开发的WebGis，需装SVG插件。(CSharp+ SVG development WebGis, need to SVG plug-ins installed.)

由坐标数据在google earth上生成路径(Path is generated on the Google Earth by coordinate data)
