Technical note

What changes when you convert ISG to WEBP

ISG is not a map but a correction grid. Each cell holds the small offset needed to move coordinates from one datum to another, or the height of the geoid, the surface that turns a GPS height into a height above sea level. Survey and GIS software applies it silently during a coordinate transformation. Rendered as WEBP, it becomes a smooth picture of those offsets, useful for documentation or teaching, while the transformation itself still needs the original ISG. ISG carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. WEBP has nowhere to record any of that. The picture transfers intact, the location does not, so the output cannot be dropped onto a map afterwards without being placed by hand. Keep the ISG original if the data still has to go back into a GIS.

Map Data Workflow

Turn GIS data into something anyone can open

A map saved as WEBP opens on any computer and any phone. reaConverter produces those from ISG in batch, entirely offline.

  • Render every file in a folder to WEBP with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • Stamp a text watermark, such as a project name or a date, on every image
  • 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.

As a graphic designer, I often receive WebP files from clients who don't know any better. reaConverter converts them to PSD or PNG with layers intact (when possible). It's the only tool that gives me back editable files. Absolute game‑changer.

I had a huge archive of WebP images from a client that I needed to convert to TIFF for printing. reaConverter handled it flawlessly – 500+ files in one go. No crashes, no quality loss. I'm genuinely impressed by the stability.

Google's WebP format is great for web performance, but not all platforms support it. reaConverter lets me convert WebP to JPEG and PNG in bulk, so I can use images everywhere. The batch processing is lightning‑fast, and the quality is identical to the original. A must‑have for any webmaster.
