I must have done this a hundred times in the past so I think I might be going crazy, but here it is. I have a file of data points collected in Nad27. I need to convert them to WGS84. I open the original file and create points using the NAD27 projection. I then save a copy of the file specifying the WGS84 projection to the new file. I then close the Nad27 table and open the WGS84 table. I then add two new columns Lat84 and Lon84 to the WGS84 table. I then open an MB window and type:
update new_table set Lat84 = centroidy (new_table.obj),Lon84 = centroidx(new_table.obj) The cloumns update, but with exactly the same numbers as the original Nad27 coordiantes. How can this be? I'm confused. I've done this a hundred times between Nad83 and Nad27 and it always works. What Am I doing wrong?
