Technical note

TPKX to CAL: what to expect from the conversion

TPKX is a tile set: the same map cut into small squares, usually 256 or 512 pixels across, at a range of zoom levels, each level holding four times as many tiles as the one above it. CAL holds one flat picture, so the zoom level is the decisive choice. A low level gives a compact overview of the whole area, while the deepest levels of a city or a country run to millions of tiles and an image far larger than any viewer will open. TPKX 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 TPKX original if the data still has to go back into a GIS.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • 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.
