Extract text from HEC-RAS geometry files (G01)
To convert G01 geometry files to another format, you need HEC-RAS or other Data software.
To convert other file formats to the "River Geometry Data" file type, you need software like HEC-RAS or a similar tool.
The .G01 file stores river system geometry data for HEC-RAS, a hydraulic modeling program developed by the US Army Corps of Engineers. It defines the physical network of a river system, including cross-sections, reaches, and junctions. Engineers use these files to build spatial models to simulate water flow and predict flood zones.
The main disadvantage of the .G01 format is its highly specialized, rigid structure. It relies on a specific coordinate syntax that standard map viewers or spreadsheets cannot natively parse. Sharing these files with non-engineers or stakeholders is frustrating because they require the full HEC-RAS desktop suite to visualize properly. Furthermore, standard web browsers cannot open or preview it.
To make this spatial data accessible, users often need to convert .G01 files to standard formats. Target formats include CSV or TXT for tabular coordinate review, or SHP (Shapefile) for spatial mapping in GIS software like QGIS or ArcGIS. Note that extracting raw coordinates may result in the loss of specific hydraulic properties and metadata attached to the river stations.
Because the .G01 file uses a highly specific domain schema, standard online converters fail to process it. They lack the engineering logic to translate river stations and bank elevations. Just drag and drop your file on convert.guru to identify the format, view it, and convert it when possible. Since .G01 files are typically plain text under the hood, our tool can inspect the file and show the internal content, allowing you to quickly read the cross-section data without installing complex modeling software.
Convert.Guru analyzes your G01 file, detects the exact format, and lets you read the text inside.
Users also converted F01, HYD and F03 files.
If you want to convert G01 file to , you can use HEC-RAS or similar software from the "River Geometry Data Storage" category. In the File menu, look for Save As… or Export….
To convert files to G01, try HEC-RAS or another comparable tool in the "River Geometry Data Storage" category.
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 G01 converter.
