Technical note

Before you convert NC4 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 line in an NC4 image is several pixels wide, so tracing it can mean different things and the mode is yours to choose. Centreline returns a single line running down the middle of each stroke, which is what a scanned drawing needs: one entity per line, snappable and dimensionable, rather than a long thin rectangle around it. Outline follows both edges and returns closed shapes, which suits clipart, logos and anything that will be filled or cut. A precision setting controls how closely the traced paths follow the pixel edges. One thing to plan for: vectorised output from this path is black and white, so colour in the NC4 does not survive as colour in the GBR.

Map Data Workflow

Turn GIS data into something anyone can open

A map saved as GBR opens on any computer and any phone. reaConverter produces those from NC4 in batch, entirely offline.

  • 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!

FAQ

NC4 to GBR Conversion

What are NC4 files?

NC4 is a file extension used for NetCDF-4, the fourth generation of the Network Common Data Form, a format for storing scientific data that is maintained by Unidata at the University Corporation for Atmospheric Research. It is widely used for weather, climate, ocean, and satellite data, where measurements are organized as multidimensional arrays, for example temperature at a grid of locations over time. A file describes itself: it holds the data together with names, units, and notes on what they mean. NetCDF-4 appeared in 2008 and uses the HDF5 format underneath, which allows data to be compressed and grouped in folders inside the file. Although the official recommendation is to use the .nc extension for all versions, some data providers choose .nc4 to mark the newer format.

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.
