Step by step

How It Works

reaConverter offers the fastest, simplest solution for converting your GRIB2 files into U3D without GIS software - all files processed on your PC for maximum privacy and speed.

Technical note

GRIB2 to U3D: what carries over and what does not

GRIB2 is made of pixels and U3D is a geometry format, so the two describe shape in fundamentally different ways. Check the result before sending it downstream: what matters is whether the output contains usable geometry or a picture placed inside a U3D container.

Map Data Workflow

Turn GIS data into something anyone can open

A map saved as U3D opens on any computer and any phone. reaConverter produces those from GRIB2 in batch, entirely offline.

  • Render every file in a folder to U3D 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.
