MAPGIS

随机生成点坐标，并且指定在一个多边形范围内部生成。当一个图形里面需要包含多个点信息就可以采用该方法。

arcgis二次开发技术资料，全部包含源代码，非常实用！-ArcGIS secondary development of technical information, all included source code, very useful!

向量，坐标旋转矩阵，四元数变换，wgs-84 utm，经纬高坐标变换类库，摘自CPS飞行模拟开源软件http://csp.sourceforge.net/wiki/Main_Page-Vector, coordinate rotation matrix, quaternion transform, wgs-84 utm, latitude and longitude coordinates transform the high-class, from the CPS open source flight simulator software http://csp.sourceforge.net/wiki/Main_Page

ArcObjects+VC 通过两个MapControl控件组合实现地图鹰眼功能。-ArcObjects+ VC through two control combinations MapControl realize Hawkeye map features.

读取shap文件的动态库，用vc编写，十分好用，c文件加入工程中太麻烦错误多，有了DLL简便很多-Shap read DLL files, using vc prepared, very easy to use, c file to project the error is too cumbersome and more convenient with a lot of DLL

按照边扩展法通过堆栈来实现Delaunay三角网的构建-The adoption of the law in accordance with the edge expansion of the stack to achieve Delaunay Triangulation Construction

ArcGIS Engine没有提供在MapControl中点击查询的命令，只是提供了ReaderControl中的使用的点击查询的命令，下面的代码就是实现点击查询并闪烁的代码。-ArcGIS Engine does not provide in the query by clicking MapControl orders, only provides a ReaderControl use clicks query command, the following code is to achieve the query and click on the flashing code.

包括部分空间算法，如计算两坐标点距离、判断两坐标点是否相等、计算叉积、计算点积、判断点p是否在线段l上、计算点bp以点op为圆心逆时针旋转dAlpha(单位：弧度)后所在的坐标点位置、计算指定半径圆上指定角度的弦长、计算由起点坐标和终点坐标构成的线段在指定距离和指定方向的垂点坐标等空间算法-Including some space algorithms, such as calculating the distance between the two coordinates to determine whether the same two coordinates to calculate cross product, point multiplication calculation to determine whether point p on line l above the calculation point to point op for bp counterclockwise rotation center dAlpha (units : radian) after the location where the coordinates of points, calculated on the specified radius of a round angle specified chord length, calculated from the starting point coordinates and end coordinates of the line constitutes a specified distance and specified direction of the vertical space coordinate algorithm

ArcGIS Engine二次开发编程实例，里面有许多有用的例子！-ArcGIS Engine secondary development of programming examples, there are many useful examples!

文件对GIS的基本构成、运行环境、数据结构、基本功能、工程设计等进行了详细的描述，对GIS开发人员有很大的帮助。-On the GIS the basic structure, operating environment, data structures, basic functions and engineering design carried out a detailed description of the development of the GIS staff very helpful.
