Hello ESRI team,

 

I have a small query regarding WGS84.img file as part of ArcGIS installation.

 

 

I have gone through very useful article. URL below:

 

Converting from orthometric to ellipsoidal heights—Help | ArcGIS Desktop 

 

As part of standard equation:

h = H + N

 

It is little confusing as it mentions:

 

h = H + N

 

Where

h = ellipsoidal height
H = orthometric (geoid) height
N = geoidal separation

What I understand is orthometric and geoid heights are different.

Which part WGS84.img is in above equation?

My Best,
Meghan S Kulkarni
