Technical note

Before you convert GRB2 to GBR

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. A GRB2 file has a pixel count and a DPI value, and no real-world size at all. GBR is a drawing where one unit means one millimetre or one inch, so the conversion has to assign a scale. Set the DPI before the run rather than resizing afterwards, then measure one feature of known length in the output and scale the drawing once to match it. Everything downstream, from dimensioning to cutting, rests on that single check.

Map Data Workflow

Turn GIS data into something anyone can open

Not everyone who needs to see GRB2 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.

As a PCB engineer, I rely on reaConverter to batch convert GBR files to PDF and PNG for client reports. It preserves layer accuracy perfectly, and the command-line automation saves me hours per project. Finally, a tool that handles Gerber files without glitches!

I firmly believe working with JPEG — the universal format supported by all devices and apps—is the wisest choice. reaConverter handles these conversions flawlessly.

FAQ

GRB2 to GBR Conversion

What are GRB2 files?

GRB2 is a file extension for the second edition of GRIB (General Regularly-distributed Information in Binary form), a World Meteorological Organization (WMO) standard for gridded weather, ocean, and climate data. Compared with the first edition, GRIB2 describes the data in greater detail and with higher precision, including coordinates stored in micro-degrees and a larger range of parameters, vertical levels, and message lengths. A file of this type is a series of messages, and a single message can contain several data fields that share the same origin and date. National weather services use it to distribute model forecasts, radar-derived products, and ocean and wave data. The same format is also found with the .grib2 and .grb extensions.

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.
