Technical note

GRIB2 to DCM: what to expect from the conversion

GRIB2 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. DCM 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 GRIB2.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to DCM 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.
