Technical note

KAP to FITS: what carries over and what does not

KAP is a raster nautical chart in the BSB format, stored with a palette of at most 127 colours and separate colour tables for day, dusk and night viewing. Only one of those tables ends up in a FITS, normally the daytime one. The georeferencing lives in the header, as reference points tying pixels to latitude and longitude, and does not carry over. Official nautical charts are licensed products, kept current by a stream of numbered corrections and valid for navigation only in a certified system. FITS output is a copy of the chart at one moment: fine for planning, teaching or a printout on the wall, and never a substitute for the official chart at sea.

Map Data Workflow

Turn GIS data into something anyone can open

A map saved as FITS opens on any computer and any phone. reaConverter produces those from KAP in batch, entirely offline.

  • Render every file in a folder to FITS 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.
