tform坐标转换命令

Program TFORM 3.0 of 2008/6/12 09:00:00 (Linux)

Specify initial coordinate characteristics:
1=Cartesian 2=Spherical 3=Geodetic 4=Local 5=Cylindrical: 1=Decimal 2=L-file (Deg Min Sec):

Input Coordinate File (return for terminal input): WARNING:090318:1355:45.0 TFORM/getsph: 14 non-standard lines read from L-file, ok if comments; numsit = 0

1=Add 2=Subtract 3=Cartesian length 4=Convert coordinate type (e.g. cartesian=>spherical) 5=Transform coordinates to another system (e.g. WGS=>SV6) 6=Estimate transformation

Specify operation: Specify output coordinate characteristics:
1=Cartesian 2=Spherical 3=Geodetic 4=Local 5=Cylindrical: 1=Decimal 2=L-file (Deg Min Sec):

Output Coordinate File (return for terminal input): Datums available from gdetic.dat:
* Ellipsoid parameters and translation/rotation of datums wrt ITRF
* New format: differs from old by making non-blank first column a comment
* and allowing for rotations, scale, and rate; datum name in cols 2-6, free format thereafter
* Units are m for a and translation, mas for rotation, ppb for scale, years for rates * Last updated by rwk 2002.9.27

很多格式的文件在windows下需要用记事本查看，但是很多断行之类的问题由于操作系统或者编码的问题出现错乱，推荐UltraEdit软件，查看文本文件的利器~专业人士都用它~谁用谁知道~

上面是一个坐标转换的GAMIT命令吧，在linux下运行的（不知道是不是GAMIT功能的一部分，因为上面写的是linux...）可以把大地坐标（经纬度）换为球坐标或者local坐标或者...坐标，应该是很强大的，而且精度应该比我们自己编的好太多了，有需要的可以研究下~
