Technical note

SG-GRD-Z to DCM: what to expect from the conversion

Every cell in an SG-GRD-Z 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 SG-GRD-Z 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

SG-GRD-Z to DCM Conversion

What are SG-GRD-Z files?

SG-GRD-Z is a compressed grid file of SAGA GIS, a free, open-source geographic information system used for terrain analysis, hydrology, soil science, and climate studies. A grid is a map made of equal cells with one value in each, such as an elevation model. The older SAGA format keeps such a grid in several separate files: one with the values, one with the description, and often one with the projection. A file with this extension packs all of them into a single archive, which is more convenient to store, copy, and send, and which takes less space because the data are compressed. The archive can be opened in SAGA GIS like an ordinary grid, without unpacking it by hand.

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.

Can reaConverter convert SG-GRD-Z to DCM?

Yes! reaConverter instantly converts .sg-grd-z to .dcm with perfect quality preservation. With its batch processing feature, you can convert multiple files at once in just a few clicks. You can even convert images directly from Windows Explorer using the right-click menu — fast and convenient.

What is reaConverter used for?

reaConverter is a Windows converter for 800+ formats, GIS data among them. For SG-GRD-Z to DCM it replaces the usual detour through QGIS, ArcGIS or ogr2ogr: add the files, pick the output format, and the whole batch converts offline. Surveyors, planners and engineering teams use it to pass data between GIS, CAD and everyday document formats.

Why choose offline conversion with reaConverter?
