Technical note

How NAT 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. A line in an NAT 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 NAT 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 NAT 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.

FAQ

NAT to GBR Conversion

What are NAT files?

NAT is the native archive format of Meteosat Second Generation (MSG), the European weather satellite series operated by EUMETSAT. A file of this type holds one full image of the Earth disk taken by the SEVIRI radiometer, which scans the whole disk every 15 minutes and records it in 12 spectral channels, from visible light to thermal infrared. Eleven of the channels have a ground resolution of about 3 kilometers at the point below the satellite, and the twelfth, a high-resolution visible channel, has 1 kilometer. Such images are the basis of weather forecasting, cloud and fog monitoring, dust and volcanic ash tracking, and climate research. A typical file is named after the satellite and the time of the scan, and it is large, because it holds all the channels together.

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 NAT to GBR?

Yes! reaConverter instantly converts .nat 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 NAT 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?
