Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to IFF 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

GEOJSON to IFF Conversion

What are GEOJSON files?

GEOJSON is a format for storing geographical data, compatible with several GIS programs. GEOJSON is a specialized version of JSON (Java Script Object Notation), an easy-to-use interchange format containing basic formatting rules for representing data, functioning as an alternative to XML. JSON files can be viewed with any text editor and are generally small-sized.

What are IFF files?

IFF is an old image format associated with Amiga computers — a brand connected to Commodore, which used to be popular in the 1980s and 1990s. Commodore was one of the first types of personal computers to gain wide popularity among home users. An IFF file most likely contains an image that was created or edited using an image handling program on an Amiga computer.
