用VB实现对AutoCAD中栅格地图的定向

The orientation of raster map in AutoCAD using VB programming

介绍了将地图数字化过程中,采用线性变换方式进行地图定向的数学模型、原理和方法,并阐述了在VB编程语言中通过AutoCAD的Raster对象和TransformBy方法对栅格地图进行定向的方法。

It introduces briefly the mathematical modes, principles and methods of linear transformation of the map orientation in the digital mapping process. And it also illustrates the methods of orientation for raster image using the object of raster and the method of TransformBy in AutoCAD platform, in the Visual Basic programming environment.
