一个集成地图分幅与编码的程序，可以方便的进行着方面的运算-an integrated map-rate and coding procedures, to facilitate the conduct of an operation

基于VS2010开发的GIS小程序，代码还是比较的简单，比较适用于初学者，可能代码还不够完善，希望广大的网友提出指正，也希望这一个代码可以帮助你们。

用c＋＋读写E00文件，文件的显示动能完全实现，但是属性数据还没能读取成功-Using c read and write E00 document, the document shows the full realization of kinetic energy, but the attribute data can be read not successful

SAGA GIS一个地理信息系统平台，用C＋＋编写，包含有常用的GIS算法，能打开E00文件和SHP格式文件-a geographic information system platform, C++, includes a list of useful GIS algorithm, can open the E00 and SHP file format

vc++ MapX二次开发中问题较多的中文标注的解决。在地图上标绘图标，可输入经纬度精确定位，并显示最多可输入50个汉字的标注，图标在地图上拖动移位，图标删除等，附带缩放、漫游、归心、状态栏显示当前鼠标位置经纬度等基本功能。-vc++ MapX secondary development of the Chinese are more marked resolved. Drawing on the map superscript superscript, enter the latitude and longitude accurate positioning, and display up to 50 Chinese characters input tagging, drag the icon on the map shift, delete the icon, etc., with zoom, roam, in the heart, the status bar displays the current mouse and other basic functions of latitude and longitude position.

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.
