Technical note

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

Geospatial coordinates are absolute positions on the earth, and they are large: a projected easting runs to six or seven digits, while latitude and longitude are small decimals. DWG expects a drawing laid out near its own origin in millimetres or inches. The geometry itself converts correctly, but it can land tens of kilometres from 0,0, or arrive at a scale where an entire county is forty units across. Zoom to extents first, then measure one known distance before dimensioning anything. An SG-GRD-Z file has a pixel count and a DPI value, and no real-world size at all. DWG is a drawing where one unit means one millimetre or one inch, so the conversion has to assign a scale. Set the DPI before the run rather than resizing afterwards, then measure one feature of known length in the output and scale the drawing once to match it. Everything downstream, from dimensioning to cutting, rests on that single check.

Map Data Workflow

From map data to a working drawing

Site plans, utility routes and parcel boundaries often start out as SG-GRD-Z and end up in DWG. reaConverter turns the layers into drawing entities in batch, so a full project folder moves across in one run.

  • Convert every layer in a folder to DWG with the same settings
  • Go the other way too, from DWG to Shapefile, when the GIS team needs the drawings back
  • Render the same data to PDF for a quick review copy
  • 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 previously used a similar program that stopped working, so I needed to find a replacement. reaConverter turned out to be the perfect solution—after reviewing the instructions on this page, I was able to convert DWG files immediately.

If you work with AutoCAD, Autodesk, or similar CAD software, you’ve likely faced format compatibility issues. Every developer seems to insist on their own proprietary formats, making conversions a real challenge. The solution? reaConverter. This tool effortlessly handles two-way conversion between dozens of specialized formats!

FAQ

SG-GRD-Z to DWG 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 DWG files?

DWG (which stands for "Drawing") is a proprietary format of AutoCAD, a program widely used for creating engineering and architectural projects. The format is also a default extension used by several other computer-aided design (CAD) pieces of software, including IntelliCAD, Caddie or DraftSight. DWG files contain complex design structures including several layers, which can be 2-dimensional or 3-dimensional.

Can reaConverter convert SG-GRD-Z to DWG?

Yes! reaConverter instantly converts .sg-grd-z to .dwg with perfect quality preservation. With its batch processing feature, you can convert multiple files at once in just a few clicks. You can even convert images directly from Windows Explorer using the right-click menu — fast and convenient.

What is reaConverter used for?

reaConverter is a Windows converter for 800+ formats, GIS data among them. For SG-GRD-Z to DWG it replaces the usual detour through QGIS, ArcGIS or ogr2ogr: add the files, pick the output format, and the whole batch converts offline.
