[求助]地图投影问题

<P>请问各位大侠：</P>
<P>投影坐标系 Xian 1980 3 Degree GK CM 108E.prj</P>
<P>lias: <BR>Abbreviation: <BR>Remarks: <BR>Projection: Gauss_Kruger<BR>Parameters:<BR>  False_Easting: 500000.000000<BR>  False_Northing: 0.000000<BR>  Central_Meridian: 108.000000<BR>  Scale_Factor: 1.000000<BR>  Latitude_Of_Origin: 0.000000<BR>Linear Unit: Meter (1.000000)<BR>Geographic Coordinate System: <BR>Name: GCS_Xian_1980<BR>Alias: <BR>Abbreviation: <BR>Remarks: <BR>Angular Unit: Degree (0.017453292519943299)<BR>Prime Meridian: Greenwich (0.000000000000000000)<BR>Datum: D_Xian_1980<BR>  Spheroid: Xian_1980<BR>    Semimajor Axis: 6378140.000000000000000000<BR>    Semiminor Axis: 6356755.288157528300000000<BR>    Inverse Flattening: 298.257000000000010000</P>
<P>可以看出，它对应的Geographic Coordinate System: <BR>为 GCS_Xian_1980</P>
<P>那么它还能对其它的大地坐标系统进行投影吗？例如GCS_WGS_1984?</P>
<P>请各位大侠帮帮忙，小弟在这谢过了~<BR><BR></P>

投影转换啊
