基于Mapobjects组件式GIS导航系统开发

MapObjects是一套制图软件集,它使程序员能够把地图加到应用程序中去。通过MapObjects可灵活地建立适合用户的地图接口。在小内存空间中,能用多种工业标准程序环境之一去建立应用程序,能够联合使用MapObjects与其他软件去实现地图与用户信息的联系。它不是为最终用户而是专门为开发人员提供的。它作为一种开发组件,十分方便地应用于大量的开发框架中,其中包括VisualBasic、Delphi、VisualC 、MicrosoftAccess、VisualFoxpro、PowerBuilder等之类的程序设计环境。文中将主要探讨用VC 来开发地理信息系统(GIS)用于GPS导航系统的GIS若干功能软件。

According to the Mapobjects Module Type GIS Navigation System Development

The MapObject is a set of graphics software, it can make the procedure member added the map to the application procedure.Using MapObjects can vividly establish map interface in keeping with customer. In small memory space, one of various procedure environments with standard industry can use to build up the applied procedure, can unite to use MapObjects and other softwareses to carry out the contact of the map and the customer information.It is not specialized for end customer but for develop what personnel provide.It is a kind of development module, and expediently applied in a great deal of development frame, among them including the Visual Basic, Delphi, the Visual C , the program design environment like the Microsoft Access, Visual Foxpro, PowerBuilder etc..This text will mainly inquire in using the VC to develop the navigation system of GIS.
