When I look at NCAT there are several options for the horizontal datum. Did OPUS report HARN and FBN lat/lon that were dependant on the SPC zone selected? Did OPUS use any other intermediate realizations between (1986) and (2007)
Specifically, if someone gave you coordinates with no metadata from OPUS observations in 2005 in north central Missouri, what would you select to convert to NAD83(2011) ?
