Technical note

How GFF and DWF differ in practice

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. DWF 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. How good the result is depends almost entirely on the GFF going in. Clean line art, a logo or a drawing scanned at 300 dpi or more traces into geometry you can work with. A photograph does not: continuous tone has no contours to follow, so tracing it produces thousands of tiny shapes and a file nobody can edit. Scan or export at the highest resolution available, and prefer a lossless original, because compression artefacts along an edge become ripples in the traced path.

Map Data Workflow

From map data to a working drawing

Site plans, utility routes and parcel boundaries often start out as GFF and end up in DWF. 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 DWF 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 needed to extract text and dimensions from DWF files for a bill of materials. reaConverter's output to SVG gave me clean, scalable graphics. I was able to import them into Inkscape and extract all measurements. A lifesaver for reverse‑engineering work.

Compared to Autodesk's own conversion tools, reaConverter delivered faster DWF-to-DWG results without a single corrupted file — critical for our firm’s archive project.

In our construction firm, we regularly receive plans in .dwfx, .dwg, and proprietary formats. reaConverter has become our standard for quick format conversions - simple enough for field engineers yet precise enough for architects.

As a long-time AutoCAD user, I was accustomed to working with DWF files. Transitioning to AutoCAD presented challenges — not just adapting to the new interface, but also converting legacy projects to the updated format. reaConverter handled the DWF-to-DWG conversions flawlessly, streamlining what could have been a tedious process.

FAQ

GFF to DWF Conversion

What are GFF files?

GFF (GSAT File Format) is a raster image format developed by Sandia National Laboratories in the United States to store images and image products from its synthetic aperture radar (SAR) systems. The name comes from the Ground-based SAR Applications Testbed (GSAT), the program in which the format was created. A file of this type consists of a header of variable length, which records the configuration and performance parameters of the instrument and the image, followed by a matrix of pixel data. The format was designed to allow custom annotation of radar images, and it has gone through several revisions as Sandia's radar programs developed. It remains the main image format of the laboratory, which keeps a large library of SAR images in this form.

What are DWF files?

DWF (Design Web Format) is a file format associated with Autodesk and its function is mainly that of facilitating the transfer of information related to a design project. As opposed to DWG files, the proprietary format of AutoCAD, DWF are more compressed and smaller in size. They can translate complicated structures related to architectural designs or engineering into a series of sheets that are easy to view and print.

Can reaConverter convert GFF to DWF?

Yes! reaConverter instantly converts .gff to .dwf 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 GFF to DWF it replaces the usual detour through QGIS, ArcGIS or ogr2ogr: add the files, pick the output format, and the whole batch converts offline.
