ArcGIS Collector - How to Collect High Accuracy Elevation Values

Hello,

 

With the recent support for high accuracy GPS receives in the ArcGIS Collector application, we are looking to use a cm accuracy GPS receiver (EOS Arrow 200) to collect accuracy horizontal and vertical elevations. I am aware that GNSS will only allow me to collect vertical elevations within 2-4cm with an open sky, but that is enough for the application we are using it for.

 

My question is, how does ArcGIS Collector handle collecting elevations? I don't have a ton of knowledge about Geoids and how this comes into play with the elevation values. Does ArcGIS Collector handle the geoid data? Is there some post processing or conversion I have to do to actually have an accuracy elevation value?


Thanks for your help!
