Technical note

MRF to GBR: what to expect from the conversion

Geospatial coordinates are absolute positions on the earth, and they are large: a projected easting runs to six or seven digits, while latitude and longitude are small decimals. GBR expects a drawing laid out near its own origin in millimetres or inches. The geometry itself converts correctly, but it can land tens of kilometres from 0,0, or arrive at a scale where an entire county is forty units across. Zoom to extents first, then measure one known distance before dimensioning anything. MRF is made of pixels and GBR stores geometry, so the conversion traces the image into real lines, arcs and polylines. The result is editable in CAD: entities can be selected, snapped to and measured, rather than a bitmap wrapped inside a GBR container, which is what a viewer or a lightweight converter usually produces. It is still derived geometry, so expect contours rather than a structured drawing. Dimensions, blocks and meaningful layer names were never in the MRF to begin with.

Map Data Workflow

Turn GIS data into something anyone can open

Not everyone who needs to see MRF data has GIS software. reaConverter renders it to GBR for a report, an email or a slide, and handles a whole folder in one run.

  • Render every file in a folder to GBR with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • Pick up new data automatically with Watch Folders, or script the job from the command line

Everything runs on your PC, which matters for cadastral, utility and client data that should not pass through an upload form.

FAQ

MRF to GBR Conversion

What are MRF files?

MRF (Meta Raster Format) is a format for very large images, such as global satellite mosaics, that was developed at NASA's Jet Propulsion Laboratory to serve maps to web browsers quickly. The picture is divided into many small square tiles, and the tiles are stored at several levels of detail, from the whole image at full resolution down to small overviews. A viewer needs to load only the few tiles that are visible, which makes it practical to browse images of enormous size. An MRF dataset is made of three files: a small readable file with the .mrf extension that describes the image, a data file with the tiles, and an index file with the .idx extension that tells where each tile is. NASA uses the format for its Global Imagery Browse Services, and Esri has helped to develop it further.

What are GBR files?

GBR is part of the Gerber group of formats — a set of standardized extensions used in the printed circuit board (PCB) industry. Gerber files include 2-D representations of various PCB images, such as copper layers, solder mask etc. They can also describe the electrical connections on such boards, or drilling and milling info associated with them. Similar formats include GBS, CMP and SOL.

Can reaConverter convert MRF to GBR?

Yes! reaConverter instantly converts .mrf to .gbr with perfect quality preservation. With its batch processing feature, you can convert multiple files at once in just a few clicks. You can even convert MRF files directly from Windows Explorer using the right-click menu — fast and convenient.

What is reaConverter used for?

reaConverter is a Windows converter for 800+ formats, GIS data among them. For MRF to GBR it replaces the usual detour through QGIS, ArcGIS or ogr2ogr: add the files, pick the output format, and the whole batch converts offline. Surveyors, planners and engineering teams use it to pass data between GIS, CAD and everyday document formats.
