Technical note

Before you convert TER to DDS

Every cell in a TER 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. TER 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 TER 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 TER 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.

Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch.

What are TER files?

The TER file format is associated with Terragen, a program specialized in creating 3D landscape images, models and animations, developed by Planetside Software. TER files are also known as "terrain files", as they contain data that helps create 3D scenery. They can be created using the Terragen software on both Microsoft Windows and Mac OS X platforms.

What are DDS files?

DDS (DirectDraw Surface) is an image file format that usually contains texture data, cubic environment maps or other type of data compressed using the S3TC (S3 Texture Compression) algorithm.
