Technical note

How HFZ and DCM differ in practice

Every cell in an HFZ 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 HFZ 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

HFZ to DCM Conversion

What are HFZ files?

HFZ is the compressed version of the HF2 terrain height map format, in which the whole file is packed with the gzip method. A height map is a rectangular grid where every cell holds the elevation of one spot of a landscape, and such grids can grow very large when they cover wide areas in fine detail. HFZ keeps them small by combining two ideas: heights are stored as differences between neighboring cells, and the author chooses how precise the heights need to be. The same data can also be found with the .hf2.gz extension. In a published comparison, a terrain saved as HFZ took about 1.4 MB, while the same terrain in the TER format packed with gzip took 1.8 MB, at equal vertical precision.

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 HFZ to DCM?

Yes! reaConverter instantly converts .hfz 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 HFZ 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?

reaConverter is a software program that is used for offline files conversion.
