Hello,

 

I am using ArcMap 10.2.2 (though not pertinent here).

 

I am trying to understand the basics of a coordinate system Datum and Transformation, but have a question, as follows: 

I information on computing a coordinate datum transformation using the "GPS Vector Components method," to perform a Transformation.  However, my information does not contain any visual graphics explaining the components involved, such as delta x,y,z, h, ecef origin, etc.   So I have to ask: Does ESRI have in their archives, white papers on this subject that give clear steps, relationships and graphic explanation of the components so I know that I understand completely and not missing a detail?

If I ran across "GPS Vector Components method" before, I didn't remember it. When I did a quick search for references, I'm finding that it refers to adjusting (post-processing) a set of GPS observations or measurements, not to converting between two geographic coordinate reference systems or datums.
