Introduction
A geoid is described as an equipotential surface that best equates to mean sea level of the earth. Geoid models are used to shift ellipsoidal heights (heights derived from GPS) to orthometric heights (heights referenced to mean sea level).
Instructions for FieldGenius
FieldGenius requires a geoid file for your location in order to store orthometric (geoid) elevations. The file should be copied into:On a mobile device:<location varies>\MicroSurvey FieldGenius\Programs\Mapping\ On a Tablet computer:C:\ProgramData\MicroSurvey\FieldGenius\<your version>\Mapping\ Note: the "ProgramData" folder is hidden by default. (Click Here to learn how to show hidden folders) On an Android Tablet running OS 6.0 or newer:/Internal storage/FieldGenius/Mapping/. NOTE: Geoids are normally downloaded directly from the Geoid catalog from within the program |

Instructions for MicroSurvey CAD products
|
MicroSurvey CAD, incad and embeddedCAD 2014 and newer support using geoid files for transforming orthometric (geoid) elevations. The geoid file(s) for your region should be copied into: C:\ProgramData\MicroSurvey\MSCAD\yyyy\mscad\Mapping C:\ProgramData\MicroSurvey\embeddedCAD yyyy\mscad\Mapping C:\ProgramData\MicroSurvey\inCAD\yyyy\mscad\Mapping Note: the "ProgramData" folder is hidden by default.

Instructions for STAR*NET
|
MicroSurvey STAR*NET supports using geoid files for transforming orthometric (geoid) elevations. MicroSurvey STAR*NET 7 (and earlier) requires that you convert the geoid file(s) into STAR*NET's "neutral" .ght format, using the free STAR*Geoid utility. Not all geoid formats are supported, please refer to your STAR*NET product manual for additional details and instructions. MicroSurvey STAR*NET V8 and newer allows you to copy the the older .ght, .bin or .byn geoid file(s) for your region directly into the following folder, and then can be selected on the Modeling tab of your Project Options: C:\ProgramData\MicroSurvey\StarNet\V#\Mapping\ Note: the "ProgramData" folder is hidden by default.
