Technical note

How GRC and JPEG differ in practice

GRC carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. JPEG 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 GRC original if the data still has to go back into a GIS. GRC stores pixels without compression loss and JPEG does not, so this is a one-way step. Choose a high quality setting, and avoid converting the same file back and forth, because each pass compounds the artefacts.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to JPEG 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.

FAQ

GRC to JPEG 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.

What are JPEG files?

JPG or JPEG is a commonly used method of lossy compression. JPEG compression is used in a number of image file formats. JPEG/Exif is the most common image format used by digital cameras and other photographic image capture devices; it is the most common format for storing and transmitting photographic images on the internet.
