Technical note

GRB2 to STEP: what carries over and what does not

GRB2 is made of pixels and STEP 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 STEP container.

Map Data Workflow

Turn GIS data into something anyone can open

Not everyone who needs to see GRB2 data has GIS software. reaConverter renders it to STEP for a report, an email or a slide, and handles a whole folder in one run.

  • Render every file in a folder to STEP 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.

reaConverter has been a huge time-saver for our team. We regularly work with CAD models in STEP format, and converting them to images or other file types used to be a hassle. With reaConverter, the process is fast, accurate, and incredibly easy to set up. The batch conversion feature is especially useful when handling large projects. Highly recommended for anyone dealing with STEP files on a regular basis.

FAQ

GRB2 to STEP Conversion

What are GRB2 files?

GRB2 is a file extension for the second edition of GRIB (General Regularly-distributed Information in Binary form), a World Meteorological Organization (WMO) standard for gridded weather, ocean, and climate data. Compared with the first edition, GRIB2 describes the data in greater detail and with higher precision, including coordinates stored in micro-degrees and a larger range of parameters, vertical levels, and message lengths. A file of this type is a series of messages, and a single message can contain several data fields that share the same origin and date.
