User is wants the terrian report from native Geopak which gives Root Mean Square Error to be added to ORD.

In Geopak there was a tool "compare point to tin" tool that provided a report. This report would provide the "Root Mean Square Error".

In ORD a tool "Points - Analyze Elevation" that will compare survey points against a terrain, but it only compares to a user input tolerance.

This was an important tool for ground truthing aerial mapping data against on the ground survey data to see if within expectable tolerance based on RSME report.
