I need to convert waypoints from State Plane, NAD 83 4302 - Utah Central,
U.S. Feet to Geographic, NAD 83. Here is some data:
nad2nad conversion (nad2nad -i spcs=4302,rev,83,feet -o 83,rev -w7
reversedConversion.txt | head -1):
data converted with corpscon:
40 17 43.03866,112 05 54.83550
I think I've got part of the solution.
Somehow your x was interpreted as zero.
If you convert x = 0; y = 7276845.40800; to LCC without further grid
interpolation, then you'll get
lat = 40d 08m 56.14988s, lon = -117d 22m 21.77314s
The Corpscon values are correct for SPCS 4302 and x = 1473458.11800; y =
7276845.40800;, also without grid interpolation.
