Technical note

How VIC and CAL differ in practice

VIC 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 VIC original if the data still has to go back into a GIS. VIC carries 16 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 VIC 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.

FAQ

VIC to CAL Conversion

What are VIC files?

VIC and VICAR are two archaic formats designed in the 1960s by NASA, particularly for storing, transferring and editing interplanetary and astronomical imaging data. The formats were later used in various other industries as well, including biomedical services, cartography and geology. Both VIC and VICAR formats are now considered rare and probably difficult to access outside specialized software.

What are CAL files?
