Technical note

SDAT to TIFF: what carries over and what does not

Every cell in an SDAT 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

Not everyone who needs to see SDAT data has GIS software. reaConverter renders it to TIFF for a report, an email or a slide, and handles a whole folder in one run.

  • 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.

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.

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.

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!

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.

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.

FAQ

SDAT to TIFF Conversion

What are SDAT files?

SDAT is the data file of the SAGA GIS grid format. SAGA (System for Automated Geoscientific Analyses) is a free, open-source GIS widely used for terrain analysis, hydrology, soil science, climate studies, and other geoscientific work. A grid in this format is a map made of equal square cells, such as an elevation model, with one value in each cell. The .sdat file holds only these values in binary form, while a small text file with the same name and the .sgrd extension describes them: the size of the grid, its position, the cell size, the type of numbers, and the value that marks missing data. A history file with the .hgrd extension and a projection file with the .prj extension may accompany them. SAGA can also pack all of these files into one archive.

What are TIFF files?

TIFF (Tagged Image File Format) is a file format for storing images, popular among graphic artists, the publishing industry, and both amateur and professional photographers in general.
