Shenzhen, in 2009 the latest vector map (MapInfo format)

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

此例主要实现了mapinfo回调函数的实现,让初学者很好体会setcallback的工作原理.-such cases main MapInfo callback function of the realization of a very good experience for beginners setcallback works.

这个是介绍如何在Arcmap中进行宏的制作,入门级,很简单-This is how to introduce macro Arcmap in production, entry-level, very simple

线型符号的制作,在此基础上可以设计更多的线型-The production of linear symbols, based on this line can be designed more

arcgis培训资料，对于想了解arcgis和即将进入arcgis领域的软件人员很有帮助-arcgis training materials, for arcgis and want to know is about to enter the field of software arcgis helpful staff

32×32的寄存器堆，它有32个32位的寄存器、两个读端口和一个写端口。该寄存器堆由3个层次共5个模块构成，最低层次的模块是D触发器，中间层次的模块包括32位寄存器、5位地址译码器、32选1多路选通器，顶层模块是寄存器堆模块。设计采用行为建模和结构建模相结合的方法，先用行为建模方法建立低层模块，然后再用结构建模方法搭建高层模块。-32 × 32 of the register file, it has 32 32-bit registers, two read ports and one write port. The register file by the three levels of a total of five modules, the lowest level module is the D flip-flop, middle-level module including 32-bit register, address decoder 5, 32 election more than one way strobe, and top-level module is Register File module. Design using behavioral modeling and structural modeling method of combining the first act of modeling methods used to establish low-level modules, then the structural modeling method to build high-level module.

本软件是一款集地图投影、坐标转换、GPS高程拟合和常用测绘工具于一身的共享软件。-This software is a set map projection, coordinate transformation, GPS Elevation fitting and mapping tools commonly used to share in the same software.
