Creating Link File for the Warp From File Tool

[AkhilChopra]

Hello,

I'm trying to use the "Warp From File" tool under Data Management Tools>Projections and Transformations>Raster. It asks for a link file for the control points. I created a tab delimited text file using excel; plotting X coordinates in Column A and Y Coordinates in Column B with a row missing to separate the Source Coordinates and the Target Coordinates (Image).

This didn't work.

Is there any reference on how the link file should be created? All I know is that the format is a .txt file. Is it best to use comma, space, tab delimited text? Do I need to add Source and Target header information? There is nothing on this subject. I know it looks like the X and Y coordinates are reversed in the source coordinates, but this is correct. 

Thank you to anyone who replies!

You need to add control points by using the Georeferencing toolbar. Once the control points are added (with their correct XY/Lat.Lon), > View Link Table > Save it s a text file.
