Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to WPG 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.

Working in a print studio means constantly juggling obscure file formats. I used to waste hours Googling converters or installing random software — until reaConverter became my Swiss Army knife. Install it once, and you're set forever. No internet? No problem!

FAQ

SG-GRD-Z to WPG 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 WPG files?

WPG (WordPerfect Graphic File) is a metafile created using WordPerfect, a text processor that can be used on MS-DOS, Windows, Macintosh and UNIX platforms.
