Extract text from Energy models (HMR)
To convert HMR models to another format, you need OziExplorer or other GIS software.
To convert other file formats to the "Raster Map Container" file type, you need software like OziExplorer or a similar tool.
The .HMR extension primarily identifies a Hydrographic Map Raster or geospatial image used by MicroImages TNTmips and OziExplorer. These files contain pixel-based map data georeferenced for navigation and terrain analysis.
Users often struggle with .HMR files because they are proprietary containers that standard image viewers (like Windows Photos or Mac Preview) cannot open. The file acts as a wrapper around the image data, locking it into specific GIS workflows. To share the map with clients or colleagues who don't have installed GIS software, the best approach is converting the file to TIFF (specifically GeoTIFF to preserve coordinates) or a standard JPG image for viewing.
Secondary Use: The extension is also the legacy project format for HOMER 2, a widely used renewable energy modeling tool. These files contain simulation data for microgrids but cannot be opened directly by the modern HOMER Pro without specific import steps. Converting these usually involves opening them in the software and exporting the data tables to CSV or XLSX (Excel).
Convert.Guru analyzes your HMR file, detects the exact format, and lets you read the text inside.
Users also converted OZF2, OZFX3 and MMI files.
If you want to convert HMR file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use OziExplorer or similar software from the "Geospatial Raster Map" 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 HMR, try OziExplorer or another comparable tool in the "Geospatial Raster Map" 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 HMR converter.
