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 STL for a report, an email or a slide, and handles a whole folder in one run.

  • Render every file in a folder to STL 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 STL 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 STL files?

STL is the proprietary format for a computer-aided design (CAD) program developed by 3D Systems. STL is an acronym for Stereolitography, which is a type of technology used for creating prototypes or patterns through 3D printing. An STL file contains a surface representation of such a model, without detailed specifications of aspects such as colours. STL files can only be opened with a limited number of programs.
