Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to STEP 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.

reaConverter has been a huge time-saver for our team. We regularly work with CAD models in STEP format, and converting them to images or other file types used to be a hassle. With reaConverter, the process is fast, accurate, and incredibly easy to set up. The batch conversion feature is especially useful when handling large projects. Highly recommended for anyone dealing with STEP files on a regular basis.

FAQ

RSW to STEP Conversion

What are RSW files?

RSW is the image version of the Raster Matrix Format, which is used by the GIS programs Panorama and Integration. While the sibling .mtw file stores elevation grids, an RSW file holds ordinary pictures, such as scanned paper maps, aerial photographs, and satellite images that serve as backgrounds for vector maps. The picture can be either a color-indexed image, in which every pixel points to a color in a table, or a full-color image. The file also stores simple georeferencing, which lets the program place the picture at the right spot on a map. Because the format was made for use inside these systems, it is little known elsewhere, and it is listed in file format registries mostly as a part of the Raster Matrix Format family.
