Technical note

Before you convert GRIB2 to TGA

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. TGA 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. GRIB2 carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. TGA 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 GRIB2 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 TGA opens on any computer and any phone. reaConverter produces those from GRIB2 in batch, entirely offline.

  • Render every file in a folder to TGA 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 TGA 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 TGA files?

The TGA (Truevision Graphics Adapter) format, also known as Truevision TGA or TARGA, is a bitmap file containing raster graphics and was initially associated with TARGA and VISTA boards. TGA files can be used on DOS, Windows and Mac OS X platforms for storing and transferring deep-pixel images. They support a color range of up to 24 bits and an 8-bit alpha channel. TGA files are associated with graphic adapters that can capture NTSC and/or PAL video images signals, and they are particularly popular in the domain of still-video editing.
