一个用dijdstra方法来求最短路径的算法，是使用VB来做的！欢迎大家多多指教！-dijdstra a method used to obtain the shortest path algorithm is to use VB to do! Welcome to a great weekend!

利用地图图层的属性项填充下拉列表。 用C#实现。-use map layer attributes the drop-down list of items packed. C# achieve.

常用地图投影转换公式。包括高斯投影、墨卡托投影、通用墨卡托投影、兰勃特投影等投影转换的详细公式。-The conversion formula commonly used map projection. Including the Gaussian projection, Mercator projection, Mercator projection GM, Lambert projection, such as the detailed formula for projection conversion.

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

Import3DAscii。　导入三维数据到文本文件，以方便其它软件的提取等操作。-Import3DAscii. Inducts the three dimensional data to the text documents, facilitates other software to withdraw and so on the operation.

opengis是gis的重要分之，这是中文的版本，需要的下载啦-gis OpenGIS is an important point, which is the Chinese version, you need to download
