Map Data Workflow

Turn GIS data into something anyone can open

A map saved as CGM 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 CGM 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.

We faced a massive challenge: digitizing 20 years of CGM archives into PNG format. Initial estimates projected months of work, but reaConverter's powerful batch processing and resolution scaling let us complete the project in weeks. Most impressively, it handled even our pre-1994 vector files flawlessly—zero errors, perfect fidelity.

FAQ

SG-GRD-Z to CGM 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 CGM files?

CGM (Computer Graphics Metafile) is a format that contains vector graphics information (clip art, drawings) associated with graphics design or CAD programs.
