2维电子地图显示程序可放大缩小、图层选择功能，学习GIS软件开发必备-Two-dimensional electronic map display program can be enlarged or reduced, layer selection function, learning GIS software development necessary

读写ESRI公司Shape格式文件的C底层类库，十分简洁强大，大名鼎鼎的OGR library中对Shape文件的IO就是用的这个库，包含完整代码，文档和测试工程，或用于C/C++，C#，VB等-Read and write ESRI, Shape file format underlying C library, a very concise powerful, the famous OGR library of Shape files IO is to use the library, contains the complete code, documentation and testing projects, or for C/C+ 2B !, C#, VB, etc.

地图打印输出的代码，可以参照这一程序用在编写gis的大型程序上。-map printouts of code can refer to the procedure used in the preparation of large gis procedures.

我这个不过初学者也可以看看，希望gis高手们也能上传些源码。-the beginners can also see hope gis masters can also upload some source.

本程序是将不同波段的遥感图象进行处理，通过主成分分析，最后合成一幅遥感图象。-the procedure is different band of remote sensing image processing, through principal component analysis, the final synthesis of a remote sensing image.

信息共享：建成体系完整、互联互通的电子政务网络系统和国土资源政务系统共建共享的信息资源库； 　　无缝集成：标准化OA、MIS和GIS的有机集成； 　　B/S结构：实现远程办公办文、远程带图作业，维护简单、安装方便 　　信息发布：通过WEBGIS在互联网上图文并茂的发布土地出让、转让，土地拍卖，土地登记、用地手续、矿产手续等各类信息。 　　二次开发：以平台为基础建立的各类应用，可以方便的进行二次开发，满足业务的各种变化需要。-information sharing : to build a complete system, interoperable e-government network systems and land resources Administrative System Sharing of information resources library; Seamless integration : standardization OA, MIS and the organic integration of GIS; B/S : remote-office run, remote operations with map and maintaining a simple, easy installation information dissemination : WEBGIS on the Internet to browse through the release of land sales and transfers, land auctions, land registration, land clearance, mineral procedures of all types of information. Second development : based platform for a variety of applications, to facilitate the conduct of secondary development to meet the business needs of the changes.

vb通讯《GIS开发者》Visual Basic 是Mcrosoft公司推出的强有力的系列开发软件之一，而且以其实用、方便、快捷、开发周期短、广泛而强大的功能越来越被广大编程人员所亲赖，广为流传，似乎有些专业的编程人员放弃了Visaul C++ 而改用了Visaul Basic之类的RAD编程工具，尽管Visaul C++在灵活性、代码紧凑、运行速度快及底层开发等方面Visaul Basic无法比拟的，但编写C++应用程序过长的调试和开发周期确实有点不适应当今的应用程序开发环境。-vb communications, "GIS" Visual Basic is Mcrosoft launched a series of powerful software development, but its practical, convenient, fast and short development cycle, extensive and powerful features are increasingly the majority of programmers are pro-Lai, the most widely circulated, it appears that some professional programmers abandoned FoxPro C and switch to the Basic FoxPro like RAD programming tools, despite the flexibility of C FoxPro, code compact, fast operation and development, and so on the bottom FoxPro Basic incomparable, but the C application debugging and long development cycle is really not suited to today the application development environment.
