Step by step

How It Works

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

Technical note

How GSB and DCM differ in practice

GSB is not a map but a correction grid. Each cell holds the small offset needed to move coordinates from one datum to another, or the height of the geoid, the surface that turns a GPS height into a height above sea level. Survey and GIS software applies it silently during a coordinate transformation. Rendered as DCM, it becomes a smooth picture of those offsets, useful for documentation or teaching, while the transformation itself still needs the original GSB.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • 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.
