Technical note

GTI to DWF: what to expect from the conversion

GTI holds no pixels of its own. It is an index: a list of other raster files plus instructions for mosaicking, clipping or rescaling them, so it converts only when every file it points to is present at the path it records. A GTI copied to another machine on its own produces nothing usable. Converting to DWF renders the assembled result into one real file, which is often the whole reason to do it. A GTI file has a pixel count and a DPI value, and no real-world size at all. DWF 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

Converting GTI to DWF usually means handing GIS data to someone who works in CAD. reaConverter makes that hand-off without a GIS seat on either side, for one layer or a whole delivery.

  • 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 came here specifically to leave this review about reaConverter. I've been using it for seven months, several times a week - and it never crashes, freezes, or slows down my system. Best part? It's incredibly lightweight. Runs perfectly on just 4GB RAM and an Intel Core i3 processor. Conversions happen in a flash, and it works completely offline!

The online converters kept corrupting my DWF files, so I installed reaConverter. It's night and day – the conversion is fast, the quality is perfect, and it works offline. No more uploading sensitive project files to sketchy websites. Highly recommend for any engineer.

FAQ

GTI to DWF Conversion

What are GTI files?

GTI (Raster Tile Index) is a small file that turns a large collection of map or image tiles into one seamless virtual picture. Instead of storing any pixels, it points to the individual raster files, which may be aerial photographs, satellite scenes, or terrain tiles, and describes where each of them lies on the map. A program that opens the GTI file sees one continuous image and loads only the tiles needed for the visible area, which makes it practical to work with archives of thousands of files without merging them first. The format appeared in 2024 and is stored as a short XML file with the .gti extension, or as a tile index in a GeoPackage or FlatGeobuf file.

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 GTI to DWF?

Yes! reaConverter instantly converts .gti 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.
