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:
On Windows Vista/7/8 or newer:
Note: the "ProgramData" folder is hidden by default.
On Windows XP or earlier:
C:\Documents and Settings\All Users\Application Data\MicroSurvey\StarNet\V8\Mapping\
Note: the "Application Data" folder is hidden by default.
