3. Select GBR as output format

Pick GBR as the output format. If the data is going back into a GIS, choose a format that keeps coordinates and attributes; JPG, PNG and PDF suit maps for reports and slides.

Technical note

How GSB and GBR differ in practice

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. GSB 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 GSB to begin with.

Map Data Workflow

Turn GIS data into something anyone can open

Not everyone who needs to see GSB 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.

Working in a print studio means constantly juggling obscure file formats. I used to waste hours Googling converters or installing random software — until reaConverter became my Swiss Army knife. Install it once, and you're set forever. No internet? No problem!

FAQ

GSB to GBR Conversion

What are GSB files?

GSB (Grid Shift Binary) is the file extension of the NTv2 format, short for National Transformation version 2, developed in Canada by Natural Resources Canada for converting map coordinates from one geodetic datum to another. When old maps were based on one model of the Earth and new surveys use another, the same place ends up with slightly different coordinates, and a file of this type records how far each point has to move. It covers an area with a net of points and stores the shift in latitude and longitude at each of them, usually together with an estimate of the accuracy. The format later spread to other countries, including the United Kingdom, Switzerland, and Australia, and it is widely used in surveying, cadastre, and GIS.

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 GSB to GBR?

Yes! reaConverter instantly converts .gsb 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 images 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 GSB 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.

Why choose offline conversion with reaConverter?
