Technical note

SG-GRD-Z to WMF: what carries over and what does not

SG-GRD-Z 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. A line in an SG-GRD-Z image is several pixels wide, so tracing it can mean different things and the mode is yours to choose. Centreline returns a single line running down the middle of each stroke, which is what a scanned drawing needs: one entity per line, snappable and dimensionable, rather than a long thin rectangle around it. Outline follows both edges and returns closed shapes, which suits clipart, logos and anything that will be filled or cut. A precision setting controls how closely the traced paths follow the pixel edges. One thing to plan for: vectorised output from this path is black and white, so colour in the SG-GRD-Z does not survive as colour in the WMF.

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 SG-GRD-Z 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

SG-GRD-Z to WMF 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 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.
