ARCGIS一些基本开发操作对初学者有一定的益处

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

结合GIS工具软件与当今可视化开发语言的集成二次开发方式是GIS应用开发的主流。它的优点是既可以充分利用GIS工具软件对空间数据库的管理、分析功能，又可以利用其它可视化开发语言具有的高效、方便等编程优点，集二者之所-GIS software tools combined with the development of contemporary visual language secondary development of integrated manner GIS application development is the mainstream. Its advantage is not only fully utilize the tools of GIS spatial database management, analysis, it could make use of other visual programming language with an efficient and convenient programming advantages, combines two pancaked

This example programming for mapobject 2.4 like displaying SHP files or grid files (*.adf) with legend manipulation. So, you must install mapobject first for editing the sorce codes. But for the execute file you just run for it.-This is example programming for mapobject 2.4 like displaying SHP files or grid files (*.adf) with legend manipulation.
