Extract text from Geographic raster files (GRI)
To convert GRI Raster files to another format, you need R Foundation or other GIS software.
To convert other file formats to the "Geographic Raster Grid File" file type, you need software like R Foundation or a similar tool.
A .GRI file is a Geographic Raster Grid data file heavily utilized by the R spatial analysis ecosystem (via the 'raster' package), DIVA-GIS, and Maxent. It stores multi-dimensional gridded spatial data, such as elevation maps, temperature distributions, or species occurrence probabilities. The format is strictly binary, designed for fast read/write operations during heavy computational modeling.
The main disadvantage of the .GRI format is that it relies on a two-file structure. A .GRI file contains only the raw numerical values; it is completely useless without its corresponding GRD header file, which stores the spatial metadata (projection, extent, resolution). If you move the .GRI file without the GRD file, the data is lost. Furthermore, standard image viewers and web browsers cannot open these files, and many modern GIS applications prefer consolidated formats.
To ensure your spatial data is portable and easy to share, you should convert the file. For universal GIS editing in tools like QGIS or ArcGIS, convert to GeoTIFF (.TIF) as it bundles data and metadata into a single file. For web previews and reports, convert to PNG or JPEG. For archiving multi-dimensional climate data, convert to NetCDF (.NC).
Convert.Guru analyzes your GRI file, detects the exact format, and lets you read the text inside.
Users also converted CPG, PRJ and DEM files.
If you want to convert GRI file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use R Foundation or similar software from the "GIS Raster Data Storage" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to GRI, try R Foundation or another comparable tool in the "GIS Raster 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 GRI converter.
