What is a GGF file?

GGF files mostly belong to Trimble Business Center. GGF files come in several distinct types that serve different domains.
For many files, GGF stands for Geoid Grid File.

This file type holds a grid of geoid model data used in geospatial applications.

It is applied to adjust GPS ellipsoidal heights to mean sea level in surveying and mapping.

Software like Trimble Business Center creates and uses these files.

In other cases, GGF may mean Gene Graphics Format.

This version can contain data or graphics connected with genealogy or genetic mapping.

Tools such as the GGF Extractor or GeneMapper handle these files.

A less common use is in gaming.

Some GGF files serve as menu or interface files for older games like MechWarrior 2.

They store layout settings for game interfaces.

FilExt.com note: Check the file header or contextual documentation to decide which format your GGF file uses. Additional details are available at the Trimble website for geoid-related information.

How to open a GGF file

You need a suitable software like Trimble Business Center to open a GGF file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your GGF file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a GGF file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert GGF files:

Trimble Business Center
See the previous paragraphs to learn more about the main application. GGF files are often referred to as Trimble Business Center gis because this type of file is primarily created or used by this software.
GPS Pathfinder Office (Geoid Grid File) by Trinble Navigation Limited
The GPS Pathfinder Office software enables you to pre-plan field sessions. The data dictionary editor creates custom pick-lists, automatic repeat feature, and numeric values. In the field, the data dictionary prompts the field crew to enter specific information for data integrity and compatibility with your GIS or database. A geoid model is a mathematical definition of the difference between WGS-84 Height and local height above mean sea level (MSL). It defines the mean sea level over a local area. A geoid grid model is a file that contains these differences for a number of positions on a grid.

GGF file extension format:

Each file has a definite file format, that is, how the stored data is arranged in the file. The file format can be deduced from the file extension and the signature. File extension, signature and file format must match; otherwise errors will occur when the file is opened. Knowledge is power - this also applies when dealing with unknown or faulty files. Our examination of the GGF files comes to the following conclusion:

The GGF file extension is not widely used. Such a file is used by a few programs, each with its own file format. But the following two file formats are common:

55% of all GGF files start with the bytes 01 00 54 4E 4C 20 47 52 49 44 20 46 49 4C 45, which are crucial for this file format. They consist of illegible, cryptic characters. Most of these files are 180 KB to 140 MB in size. The file type was created 10 years ago, but is still used today. The keywords TNL GRID FILE, Global and Geoid are typical for these files. A usual file name is EGM08-25.GGF or EGM08-1.GGF. Such files sometimes refer to geoid.
15% of all GGF files start with the magic bytes 00 00 54 4E 4C 20 47 52 49 44 20 46 49 4C 45, which are always the first bytes of this file format. They consist of illegible, cryptic characters. Most of these files are 10 KB to 14 MB in size. The files contain the following words: TNL GRID FILE and Geoid. G18US.ggf is a typical file name.

The remaining 30% of all GGF files are different files with different signatures. Often described as osgm. If you want to find out which format your GGF file belongs to, just click on the button "Choose your .ggf file to analyze".

How to solve problems with GGF files

Associate the GGF file extension with the correct application.
Update your software that should actually open data files. Because only the current version supports the latest GGF file format. Search, therefore, e.g. on the manufacturer website after an available Trimble Business Center update.
To make sure that your GGF file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
