I am going to use APPM, and I have experience with tpoint.
In Tpoint you can define a set of points close together to quickly start with the corrections and then continue on more distant points.
I wonder if this is feasible in APPM:
-set an initial group of points
-define subsequent groups of points , that enter the models
-define the points by azimuth and altitude.
Not that this is strictly needed , it is just that I am used to this way of working and want to leverage on my experience if possible.
