Convert TER to DCM

Online GIS converters cap file size and need an upload. reaConverter converts TER to DCM locally, whatever the size of the dataset.

TER to DCM conversion is faster with the right tool. reaConverter handles everything from a few files to thousands in one batch. Processes files consistently every time, with full control over quality and output settings. Handles whole folders of tiles and layers in one run, with identical settings on every file.

Technical note

TER to DCM: what to expect from the conversion

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. DCM 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 DCM returns a shade, not an altitude. Missing cells in an elevation grid, such as water, radar shadow or the edge of a survey, are not empty: they hold a sentinel value, -32768 in SRTM, -32767 in DTED and very often -9999 in ESRI grids. Counted as a real height, that value stretches the scale so far that the actual terrain collapses into a few near-identical shades. When a DCM output looks flat and washed out, a void treated as data is the usual cause.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to DCM 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

TER to DCM Conversion

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 DCM files?

A DCM file is a DICOM file, meaning it follows the Digital Imaging and Communications in Medicine (DICOM) standard for storing, transmitting, and managing medical imaging data. This standard ensures interoperability between medical imaging equipment and software, allowing images to be shared across scanners, servers, workstations, and network systems. DCM files are most commonly used in hospitals, clinics, and private medical practices that rely on medical imaging equipment such as CT, MRI, and ultrasound devices.
