Technical note

GEOJSON to DCM: what to expect from the conversion

A GEOJSON file holds geometry and an attribute table, and nothing at all about appearance. Colours, line weights, fills and labels are properties of the GIS project rather than of the file, which is why the same GEOJSON looks different in every program that opens it. The DCM render therefore falls back on defaults and will not match the styled map you see in QGIS or ArcGIS. Expect a clean drawing of the geometry rather than a finished cartographic product. GEOJSON describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the DCM afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.

Map Data Workflow

Turn GIS data into something anyone can open

Not everyone who needs to see GEOJSON data has GIS software. reaConverter renders it to DCM for a report, an email or a slide, and handles a whole folder in one run.

  • 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

GEOJSON to DCM Conversion

What are GEOJSON files?

GEOJSON is a format for storing geographical data, compatible with several GIS programs. GEOJSON is a specialized version of JSON (Java Script Object Notation), an easy-to-use interchange format containing basic formatting rules for representing data, functioning as an alternative to XML. JSON files can be viewed with any text editor and are generally small-sized.

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.
