NAD83 TM COORDINATE TO GEOGRAPHIC?
Well, I had to recreate a spreadsheet to convert NAD83 TM coordinates to Geographic and back because the original seems to have “corrupted” itself. Manual NOS NGS 5 contains all the constants and all the formulae, so it’s just a matter of powering through it. However, I’m getting one little headache using term “n^2” as defined on page 33. When I apply it to the formulae on page 36 with my TM constants I must be doing something wrong.
In Constants B2, B4, and B6 if I square it I get the wrong answer.
In Constants B3 and B5 if I square it I get the correct answer.
I’m attaching the XL sheet, if anyone would take a look and give some feedback I’d appreciate it.
