FieldGenius now supports the Gsigeo2011_ver1 Geoid Model for Japan.  

This program has been created after obtaining approval from the director of the Geospatial Information Authority of Japan using the technical document “H1-NO.2 the coordinate transformation software TKY2JGD for geodetic results. (Approval number:  国地企調第362号 2nd March, 2015)


This geoid model isn't installed with FieldGenius and must be copied manually onto each data collector you want to use this geoid file.

Steps to Install:

  1. Download the Gsigeo2011_ver1 Geoid Model and save it to your computer.
  2. Connect your data collector to your computer and find the location where FieldGenius is stored.  You will be able to find the Mapping folder in the \MicroSurvey Fieldgenius\Programs\Mapping folder.
  3. Copy the .byn file from your computer into the MicroSurvey Fieldgenius\Programs\Mapping directory on the data collector.

Steps to Use Gsigeo2011_ver1 as a Geoid File.

  1. When you define your coordinate system in FieldGenius, you can set the Vertical System to Gsigeo2011_ver1.byn
  2. From the Main Menu | Settings | Coordinate Systems change the Vertical Systems to Gsigeo2011_ver1.byn.
  3. Your GPS derived coordinates will now have orthometric heights derived from the Gsigeo2011_ver1 geoid model.
