Sorry, that is my fault on the feet and yards. I was in a rush.
But you bring up my other problem.
I used Emlid Reach RS2 and + to get my GCPs. They give the vertical in ellipsoid as we can see with the negative values.
How can I get my output to show the orthmetric height?
Here is how I am trying to do it in Pix4D.
My Emlid RS2 (Base) is on an accurate geodetic control point that gives me its coordinates and vertical ellipsoid, geoid and orthometric height.
Plan to obtain orthometric height for all GCP and CP:
What I have:
Datasheet on geodetic control point with ellipsoid, geoid and ortho height:
Ellipsoid height on geodetic control point
Ellipsoid height on my GCPs obtained with Reach RS2 on control point
Base: Ortho Height 2.020, Ellipsoid: -32.371
GCP and CP ellipsoid heights: varying
I took the ellipsoid GCP heights and subtracted them from the RS 2 Base ellipsoid (-32.371) and this is now column F
I then took column F and added it to the RS 2 Base ortho height of 2.02 and got my ortho height in column G
Column G is now what I want to use as my vertical height for my GCPs.
Is this correct? Or am I overlooking something?
