RE: MI Problem with transforming coordinates

[Anonymous]

Daniel,

 

You should not expect the coordinates to be transformed in the table. The affine clause is only activated when importing/reading the table. To obtain the "transformed" coordinates, you open the table with the affine and save a copy in the same projection without the affine.

 

At least, it's what I did in the past.

 

Good luck.

I am having trouble transforming coordinates using the "Commit table" statement. All I need to do is a linear shift of the X,Y cordinates of -4000,529600.  Shown below is the code that I am trying to use, the result of which is absolutely no change in the coordinates.

 

set map coordsys earth projection 8, 74, "m", -123, 0, 0.9996, 500000, 0

set coordsys earth projection 8, 74, "m", -123, 0, 0.9996, 500000, 0

 

commit table grid as "c:\data\stevesapp\test" coordsys earth

  projection 8, 74, "m", -123, 0, 0.9996, 500000, 0

  affine units "m",0,1,-4000,1,0,5296000
