Does the extended report contain the orthometric height in feet anywhere? I've been converting it using Corpscon with the updated geoid stored per corspcon instructions, but since the have the coordinates in feet I thought maybe the height was there also.
I typically use a network setup, but periodically I use OPUS as a check on control.

I have not seen it either, I just use a calculator and divide by 0.3048.

Good point....I guess the geodetic part is already done. Just converting units...
Well "technically" you should multiply by 3.280833333333...
NAVD88 is in US Survey Feet, not International Feet. But the difference is only about 0.01 ft. in Denver!

To be pedantic, the exact conversion factor for meters to US Survey Feet is: 3937/1200. See: http://www.ngs.noaa.gov/PUBS_LIB/FedRegister/FRdoc59-5442.pdf

I find that easier to remember than 3.280833333333 anyway.

I know technically you are, but for us flatlanders it is about the same and a lot easier to key in. We do use the correct conversion number for horizontal.

No,
My most recent extended results:
"Note the Board will not let me paste in portions of it. They flash in this window then disappear."
The extended output gives SPC N & E in the State specific feet, but Orthometric height is in meters.
In the report I attempted to post, the orthometric height was 0.3m different from GEOID12B to the new prototype GEOID16B.
