Technical note

How GRC and WMF differ in practice

GRC is made of pixels and WMF stores geometry, so the conversion traces the image into paths. Once traced, the artwork scales to any size without softening, which is the point of the exercise. It is a reconstruction rather than the original drawing: curves are fitted to the pixel edges, so the cleaner and sharper the source, the closer the paths follow what the designer intended. Lettering in the image is traced as shapes, not recognised as text. Every character arrives as an outline that can be scaled and edited like any other geometry, but not retyped, restyled or searched, and no font is attached to it. Titles and callouts on a scanned drawing usually have to be typed again in the WMF if they need to stay editable.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to WMF 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.

FAQ

GRC to WMF 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 WMF files?

The WMF (Windows Metafile) format represents an image file with vector graphics, bitmap components or raster graphics, consisting mainly of drawing operations and commands. It was developed and released in the late 1980s by Microsoft and it included a 16-bit structure. In time WMF files were replaced by EMFs, featuring a 32-bit structure. WMFs are currently compatible with some programs from the Microsoft Office pack, such as Word, Power Point or Publisher.
