OpenGIS协会 OGC 制定的关于地理实体结构、方法的实现标准，这里给出了COM/OLE的实现规范，包括点、线、面、空间参考系统等一系列的实现标准规范，有C...

基于ArcGis 10.2 Engine, 桌面程序，比ArcGis Map快很多基于ArcGis 10.2 Engine, 桌面程序。比打开ArcGis Map快很多，是做基于桌面程序的很好的起点，在此基础上扩展相应功能。可处理MXD文件，有基础图形工具。程序中顶部是工具条，下部左是图层控制窗，有菜单开关；下部右是地图控件。

利用VC sharp 和 MapObjects 编写的基本功能-VC sharp and MapObjects prepared the basic functions

本程序为大地测量中高斯投影坐标计算的，包括了正算和反算-This procedure for the geodetic coordinates of Gauss projection calculations, including the calculation of the positive operators and the anti-

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

用mapinfo_mapbasic+vb做的鹰眼地图功能,思路清晰,希望能对大家的学习有所帮助-mapinfo_mapbasic vb do with the Hawkeye mapping functions, clear ideas and we hope to learn some help

VB6.0+MAPX开发原理-VB6.0 Connection Principle Development

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
