Technical note

GRIB2 to GBR: what to expect from the conversion

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. GRIB2 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 GRIB2 to begin with.

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 GRIB2 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

GRIB2 to GBR Conversion

What are GRIB2 files?

GRIB2 is the second edition of the GRIB standard of the World Meteorological Organization (WMO), introduced in the early 2000s to replace the first edition. It stores weather, ocean, and climate data on a grid, and it is now the main format used by national weather services for publishing model forecasts, radar-based products, and wave and sea condition data. Compared with the first edition, it describes the data more precisely, supports many more kinds of products, and allows larger messages, so that a modern global forecast can be stored without loss of detail. A single file may contain many fields, such as pressure, wind, and precipitation, for different times and heights. The format is also found with the .grb2 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.
