Opening a GSI File

The GSI file type is primarily associated with Leica Geo Office.

GSI	File extension: GSI
	File type:	geospatial survey data file

What is a GSI file?

GSI files mostly belong to Leica Geo Office. GSI files are geospatial survey data files that store measurement and coordinate data captured by surveying instruments. They are used mainly for recording geodetic and geotechnical data during field surveys.
Usage Details:

Data Type: Contains readings and position measurements from surveying devices.
Format: Can be a simple internal file or a ZIP-compressed package.
Software Support: Designed to be used with specialized applications such as Leica Geo Office, GSI Viewer, or Geomagic Studio.
Applications: Facilitates the exchange of geospatial survey data and supports analysis of field measurements.

FilExt.com tip: Use dedicated geospatial software to open these files so that all the measurement details are correctly interpreted.

How to open GSI files

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

Your GSI file will then be displayed in the browser.
Now click on "Save as..." at the top of the page.
Then choose the file format (e.g. JPG, PDF, DOCX, TXT, ...) you want.
Your file will be converted and downloaded.

Programs that open and convert GSI files:

Leica Geo Office
See the previous paragraphs to learn more about the main application. GSI files are often referred to as Leica Geo Office gis because this type of file is primarily created or used by this software.
GeneSys (Remote Administration File) by Psytech International
GeneSys can administer, score and generate reports on virtually any psychometric test, questionnaire and most surveys. The GeneSys3 Remote Administration system generates item response (.GSI) files which can then be imported into the main system for scoring and reporting.
GPS Tuner (Map Slices Calibration Data) by Megalith-Systems
GPS Tuner is an off-road navigation software for Pocket PC devices. While most car navigation software gives you the possibility of planning your route based on a road network, GPS Tuner gives you the ability of navigation where the roads end. GPS Tuner is an tool for hiking, geocaching, boating, flying, driving and many other sporting activities.

GSI file format:

To find out what program is needed to open GSI files, you need to determine the file format. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. File extension, signature and file format must match; otherwise errors will occur when the file is opened. So you need a detailed analysis of a file to find out the format and the associated program. In the following you will find our evaluation of the GSI files:

The GSI file ending is used by a few programs, each with its own file format. But the following two file formats are common:

45% of all GSI files use the same file format, which have the signature *11. If you open these files in a text editor, you can view and read the content yourself. The files are 990 bytes to 51 KB in size, with a median of 9 KB. The file type was created 10 years ago, but is still used today. Certain words are almost always found in the files, such as 110001, 110002 and 0000000000000000.
20% of all GSI files start with the bytes 11 crucial for this file format. The content consists of readable text data, which can be read using a text editor. Most of these files are 520 bytes to 31 KB in size. The following keywords are characteristic: 110001, 110002 and 110003. The file name 20180601.GSI is characteristic of these files.

All other GSI files (35%) have no uniform format, often e.g. ZIP. The category is slot. You can get all the details of your GSI file by dragging it onto this page or by clicking the button "Choose your .gsi file to view" above.

How to solve problems with GSI files

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