All about IFG Files

The IFG file type is primarily associated with GAMIT/GLOBK.

IFG	File extension: IFG
	File type:	InSAR image data

What is an IFG file

IFG files mostly belong to GAMIT/GLOBK. An Interferometric Synthetic Aperture Radar (InSAR) image file format commonly associated with processing and analysis of InSAR data. InSAR is a remote sensing technique that uses radar signals to measure ground deformation and create digital elevation models. The *.IFG file likely contains the interferogram, which is the difference between two radar images acquired at different times, allowing for the detection of subtle changes in the Earth's surface.

How to open an IFG file

You need a suitable software like GAMIT/GLOBK to open an IFG file. You need a suitable software like GAMIT/GLOBK to open an IFG 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 IFG file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a IFG file directly in the browser:. Just drag the file onto this browser window and drop it.

4 Steps to Open an Unknown .IFG File

Because .IFG files come from various programs, they aren't universally openable.

Identify the Source: Files from geodesy researchers or satellite radar workflows are usually Geospatial/Remote Sensing Data (specifically InSAR image data).
Check the Header: Inspect the first bytes in a hex or text editor:
- Readable text (e.g., XML) suggests configuration metadata.
- "PK" indicates a zipped archive.
- Unreadable binary often implies a raw interferogram raster.
Use the Original Software: You usually need the original program to open it; likely tools include GAMIT/GLOBK or similar InSAR processing software. If unsure, ask the sender.
Use this Webpage: Drag and drop your .IFG file into our viewer to detect its format, extract readable metadata, and preview contents when possible.

How to solve problems with IFG files

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