Technical note

How GRIB and AVIF differ in practice

GRIB is a container for scientific arrays, not a picture. One file usually holds several variables, such as temperature, pressure or wind, often across a series of time steps and a stack of vertical levels, each stored as floating-point values in its own units. AVIF holds one flat image, so the conversion has to reduce all of that to a single slice and map its values onto shades. Treat the result as a snapshot for a report or a slide: the data itself stays in the GRIB. GRIB carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. AVIF has nowhere to record any of that. The picture transfers intact, the location does not, so the output cannot be dropped onto a map afterwards without being placed by hand. Keep the GRIB original if the data still has to go back into a GIS.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to AVIF 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.
