How It Works

reaConverter offers the fastest, simplest solution for converting your DT2 files into DDS without GIS software - all files processed on your PC for maximum privacy and speed.

Technical note

How DT2 and DDS differ in practice

Every cell in a DT2 file holds a measurement rather than a colour, usually elevation in metres, running from sea level up to whatever the highest point in the tile happens to be. DDS stores brightness, so the conversion stretches that range across a grey or colour scale. What you get is a readable picture of the terrain, and it is the right thing for a relief map or a figure. What you no longer have is the data: sampling a pixel in the DDS returns a shade, not an altitude. DT2 carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. DDS 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 DT2 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 DDS opens on any computer and any phone. reaConverter produces those from DT2 in batch, entirely offline.

  • Render every file in a folder to DDS 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.
