摘　　要：通过R2V引入Maplnfo矢量图层窗口的栅格图像及相应的矢量图层，依据矢量图层上的标记点重新设定控制点，再将矢量图层导出为新的MapInfo矢量图层，实现了Maplnfo矢量图层的再校准。按照高斯一克吕格直角坐标编辑控制点的坐标值，并依据不同的分带号编辑mif文件，可实现非地理坐标向地理坐标的转换。本方法也可应用到其他GIS软件中矢量图层的再校准及投影变换。By importing the raster image and the corresponding MapInfo vector layer and setting up new control points according to the mark points on the vector layer, the re-registration of MapInfo vector layer may be realized by R2V after exporting to a new mif file. The transformation of non-earth coordinate to Gaus-Krugger zoned projection may be obtained by imputing correct Gaus-Krugger coordinates into the control points and editing the exported mif f＇fie with appropriate parameters according to the zone number and the central longitude. This method may be also applied to the re-registration of vector layer of other GIS system.
