Our enterprise data (typical local gov datasets) is in NAD_1983_StatePlane_Nevada_West_FIPS_2703_Feet and datum=D_North_American_1983. We have some new 3DEP lidar data that uses D_NAD_1983_2011, so I want to understand the differences between the two datums.
I've used the nifty NGS NCAT program to calculate the absolute XY shift between the two datums in our vicinity:
My question is: Why can't I get the same result in ArcMap?
The transformation used above was automatically plugged in by ArcMap - I didn't select it. Resulting coordinates in NAD1983_2011 are shown as X2 and Y2 below.
