Step by step

How It Works

reaConverter offers the fastest, simplest solution for converting your TOPOJSON files into MIF without GIS software - all files processed on your PC for maximum privacy and speed.

Technical note

How TOPOJSON and MIF differ in practice

TOPOJSON stores topology: a border shared by two neighbouring areas is recorded once, as an arc both polygons refer to, and coordinates are usually quantised to integers to save space. MIF stores each feature independently, so every shared border is written twice and the file grows. Coordinates are decoded back to real positions, at the precision the quantisation left them. Both TOPOJSON and MIF are georeferenced, and the coordinate reference system is the part that usually breaks. Confirm the projection of the output rather than assuming it survived, because data that lands in the wrong part of the world still opens without an error.

Map Data Workflow

Move GIS data between formats

Data deliveries rarely arrive in the format a project runs on. reaConverter takes TOPOJSON to MIF on your own PC, file after file, with nothing uploaded.

  • Convert an entire delivery folder to MIF in one run
  • Produce several formats from the same source for different teams
  • Leave the originals untouched and write the results to a folder of your choice
  • 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.
