Technical note

Before you convert GRD 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 GRD 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 GRD 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

GRD to GBR Conversion

What are GRD files?

GRD is a file extension shared by several grid formats, which store a map as a regular net of cells with one value in each cell. The best known is the Surfer grid of Golden Software, used for contour maps and 3D surfaces of elevation, geology, and other measured data, and it exists in text and binary versions. The Northwood numeric grid, created for the Vertical Mapper add-on and now associated with MapInfo, serves a similar purpose and is common in mapping and telecom planning. The R programming environment uses .grd for the header of its native raster files, with the values kept in a separate .gri file. Because the same extension covers all of these, the contents of a file, not its name, tell which one it is.

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 GRD to GBR?
