Technical note

What changes when you convert SDAT to PNG

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. PNG 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 PNG 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 PNG 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 PNG opens on any computer and any phone. reaConverter produces those from SDAT in batch, entirely offline.

  • Render every file in a folder to PNG 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.

For my game development sprites, I need PNGs with perfect compression. reaConverter lets me fine-tune the color palette and compression level. It even preserves metadata. This is the only converter I trust for my asset pipeline.

I love that reaConverter can convert PDF pages to individual PNGs. I used it to extract images from a scanned document – each page became a high-res PNG with zero loss. It's like magic, but it actually works every time.

My product photos always come out with messy backgrounds. I use reaConverter to convert them to PNG with transparency – it handles the conversion flawlessly. Then I drop them into my e‑commerce templates. Clean, professional, and so easy!

I design stickers but could never cleanly resize my PNG logos without pixelation. reaConverter’s PNG-to-SVG tool keeps everything sharp—even when scaling up. My Etsy shop looks way more professional now!

FAQ

SDAT to PNG 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 PNG files?

The PNG (Portable Network Graphics) file format was designed in the mid-1990s as an improved alternative to the previously existing JPG and GIF formats, and as an extension which would be particularly web-friendly. In time, PNG files have gained a wide popularity and are highly appreciated at the moment for their ability to provide a lossless compression of images, which translates in high-quality and detailed renderings.
