Technical note

RST to DWG: what to expect from the conversion

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. A line in an RST 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 RST does not survive as colour in the DWG.

Map Data Workflow

From map data to a working drawing

Site plans, utility routes and parcel boundaries often start out as RST 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.

My son is training to become an architect, so he's learning Autodesk, AutoCAD, and other design software. With so many file formats in this field, we needed a reliable conversion tool fast. reaConverter was the perfect solution - lightning-fast conversions, zero lag, and it works completely offline!

I needed to convert DWG to DXF for a laser cutter, and reaConverter did it flawlessly. The geometry remained intact, and the line weights were preserved. I've tried free tools, but they always mess up arcs. This is the only one I trust.

The program's interface is refreshingly simple and intuitive. The entire process is streamlined to just a few steps: specify your source files, set an output folder, and you're done! Batch processing works flawlessly too. An excellent tool that makes file conversion effortless.

I inherited a mess of DWG files from a previous engineer – all in different versions. reaConverter batch‑converted them all to a single, clean DWG format (2018) with no errors. It even fixed some corrupt headers. This tool is a miracle worker.

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

RST to DWG Conversion

What are RST files?

RST is the raster image file of IDRISI, a GIS and remote sensing system developed by Clark Labs at Clark University in the United States and later renamed TerrSet. A file of this type holds a single layer of a map, such as a land cover classification, a soil map, an elevation model, or one band of a satellite image, as a plain grid of values. The meaning of the numbers is not stored in the file itself but in a small text file with the same name and the .rdc extension, which gives the number of columns and rows, the type of the values, the coordinate system, and the range of values. A color table may come in a third file with the .smp extension. Files in this format were originally saved with the .img extension, which was changed to avoid confusion with other formats.

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 RST to DWG?
