Technical note

Before you convert GXF to TIFF

Every cell in a GXF file holds a measurement rather than a colour, usually elevation in metres, running from sea level up to whatever the highest point in the tile happens to be. TIFF stores brightness, so the conversion stretches that range across a grey or colour scale. What you get is a readable picture of the terrain, and it is the right thing for a relief map or a figure. What you no longer have is the data: sampling a pixel in the TIFF returns a shade, not an altitude. Missing cells in an elevation grid, such as water, radar shadow or the edge of a survey, are not empty: they hold a sentinel value, -32768 in SRTM, -32767 in DTED and very often -9999 in ESRI grids. Counted as a real height, that value stretches the scale so far that the actual terrain collapses into a few near-identical shades. When a TIFF output looks flat and washed out, a void treated as data is the usual cause.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to TIFF with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • Stamp a text watermark, such as a project name or a date, on every image
  • 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'm a graphic designer, and I often receive TIFF files from photographers. reaConverter converts them to editable PSDs with layers intact (where possible). It even keeps the colour profiles. This has streamlined my collaboration with clients tremendously.

My scanner saves everything as massive TIFF files, which are impossible to email. reaConverter lets me batch-convert them to searchable PDFs with tiny file sizes. My clients actually get their documents now!

My scanning software outputs TIFF, but I need PNGs for my website. reaConverter batch‑converts hundreds of TIFFs to PNG with perfect colour fidelity. The process is lightning‑fast, and the interface is so intuitive that even my non‑tech assistant uses it.

I work in medical imaging, and we receive TIFFs from various sources. reaConverter converts them to DICOM‑compatible formats while preserving all pixel data. It's HIPAA‑friendly because it works offline – no data leaves our network. Essential for our lab.

As a book scanner, I deal with TIFF files daily – they're huge. reaConverter compresses them to PDF or JPEG without losing any detail. I've saved terabytes of storage and still have archive‑quality images. This software paid for itself in storage costs alone.

FAQ

GXF to TIFF Conversion

What are GXF files?

GXF (Grid eXchange File) is an open text format for exchanging gridded data between different programs. It was developed by Geosoft, a Canadian company that makes software for geophysics, and it became the standard way of passing gravity and magnetic survey maps between systems. Such a map is a net of equal cells, and each cell holds a measured value, for example the strength of the Earth's magnetic field. A GXF file stores these values as plain text, together with the information needed to place the grid on the ground, such as the spacing between points and the map projection. Because the file can be opened in any text editor and does not depend on the software that made it, it is also used to share elevation data and other kinds of surfaces.

What are TIFF files?
