I am a beginner at ArcGIS and i do have a question related to coordinate system conversion.
I just need to convert coordinates from WGS84 UTM 37S to ARC 1960? I know that is horizontal conversion. My question is do i still have to do vertical datum transformation though i am concerned with equivalent horizontal coordinates? Another thing is i would do the WGS84 37S to ARC 1960 projection in Arcmap 10.3. But the vertical transformation in Geographic Calculator software. Is that correct?
Thank you in advance.
