Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to TIFF 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.

I'm a graphic designer, and I often receive TIFF files from photographers. reaConverter converts them to editable PSDs with layers intact (where possible). It even keeps the colour profiles. This has streamlined my collaboration with clients tremendously.

I needed to convert TIFF to multi‑page PDF for an archive project. reaConverter handled it effortlessly – 2,000 pages in one batch. The output PDF was searchable (thanks to OCR) and had the same resolution as the originals. Absolutely brilliant.

I work in medical imaging, and we receive TIFFs from various sources. reaConverter converts them to DICOM‑compatible formats while preserving all pixel data. It's HIPAA‑friendly because it works offline – no data leaves our network. Essential for our lab.

As a book scanner, I deal with TIFF files daily – they're huge. reaConverter compresses them to PDF or JPEG without losing any detail. I've saved terabytes of storage and still have archive‑quality images. This software paid for itself in storage costs alone.

My scanning software outputs TIFF, but I need PNGs for my website. reaConverter batch‑converts hundreds of TIFFs to PNG with perfect colour fidelity. The process is lightning‑fast, and the interface is so intuitive that even my non‑tech assistant uses it.

FAQ

GRC to TIFF Conversion

What are GRC files?

GRC is the classified grid format of Vertical Mapper, a spatial analysis add-on originally created by Northwood Geoscience in Canada and later acquired by MapInfo. A file of this type is a map made of equal cells, and each cell carries a category rather than a measurement, for example a land use class, a soil type, or a signal strength range. The category names and colors are stored with the map, so it can be displayed immediately. Its numeric counterpart, the .grd file, stores smoothly varying values such as elevation. The GRC format is widely used for mobile network planning, where coverage predictions around cell towers are saved as classified grids, and it is also used in mapping, environmental analysis, and land management.
