Technical note

RIK to CAL: what to expect from the conversion

RIK carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. CAL 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 RIK original if the data still has to go back into a GIS. RIK carries 8 bits per channel and CAL carries 1, so tonal steps get coarser during conversion. It shows up first in smooth gradients such as skies. If the result will be edited further, move to a 1-bit format only at the very end.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to CAL 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.

Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch.
