Extract text from GSI files
To convert your GSI file to another format, you need Leica Geo Office or other GIS software.
To convert other file formats to the "Survey Measurement Data" file type, you need software like Leica Geo Office or a similar tool.
The .GSI file extension primarily represents the Geo Serial Interface format, a proprietary ASCII-based data structure developed by Leica Geosystems for their surveying instruments, including Total Stations and Digital Levels. These files store raw observational data in rigid 8-character (GSI-8) or 16-character (GSI-16) blocks, recording angles, distances, and coordinates.
While essential for data collection in the field, .GSI files present significant challenges for downstream processing. The format is cryptic and not natively supported by most standard CAD or GIS applications like AutoCAD or ArcGIS. Users often struggle with the need to manually parse the rigid block structure or purchase expensive proprietary suites like Leica Geo Office just to view their measurements. Additionally, legacy GSI-8 files truncate data, leading to potential precision loss in high-accuracy projects.
To make this data usable, conversion is critical. For engineering and drafting, the best practice is converting .GSI to DXF or DWG, allowing immediate import into CAD environments. For data analysis and reporting, converting to CSV or XLSX makes the observational data accessible in spreadsheets. For geospatial visualization, converting to KML allows users to view survey points on Google Earth. Occasionally, a .GSI file may be a Golden Software Interchange file used by Golden Software Surfer, or a game save from Arcanum.
Convert.Guru analyzes your GSI file, detects the exact format, and lets you read the text inside.
Users also converted TXT, CSV, DXF, XLSX, IDX, GIS, DWG, PDF, ZIP, ASC, KML, XLS and JPG files.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our GSI converter.
