Technical note

DEM to JPG: what to expect from the conversion

Every cell in a DEM 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. JPG 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 JPG 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 JPG 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 DEM data has GIS software. reaConverter renders it to JPG for a report, an email or a slide, and handles a whole folder in one run.

  • Render every file in a folder to JPG 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.

The best part about reaConverter? It works offline. I often work on a plane with no Wi-Fi, and I need to convert design mockups to JPEG for presentations. This software never lets me down. Fast, reliable, and the output is always perfect.

I run a small real estate agency, and we take hundreds of property photos in RAW. Converting them to JPEG for listings used to be a nightmare – until reaConverter. Now I just drop all CR2 files into the batch, set output to JPEG, and within minutes I have web-ready images. The quality is pristine, and the file sizes are perfect for our site. This tool literally pays for itself in time saved.

I was stuck with 500+ BMP files from an old project – they were huge and unusable. reaConverter turned them all to JPEG in about 3 minutes. No quality loss, no hassle. I wish I had found this earlier instead of wasting hours with online converters.

My grandmother sends me photos from her old digital camera, but they're always in some weird format. reaConverter turns them into JPEGs in two clicks. Now I can print them for her photo album without any tech support calls. She thinks I'm a genius – and honestly, reaConverter deserves the credit!

FAQ

DEM to JPG Conversion

What are DEM files?

DEM is a text-based digital elevation model format originally developed by the United States Geological Survey (USGS) for its national series of terrain data, and adopted by Natural Resources Canada for the Canadian Digital Elevation Data (CDED) product. A file of this type stores a regular grid of terrain heights derived from topographic maps, aerial photography, or other sources, and is organized into a header record, a series of elevation profiles, and an optional accuracy record. The header describes the quadrangle name, the coordinate system, the units, the corner coordinates, the elevation limits, and the grid spacing. USGS files are distributed as 7.5-minute quadrangles with 30-meter spacing in UTM coordinates, or as 1-degree units with 3-arc-second spacing, while CDED files are based on National Topographic System map sheets and use geographic coordinates.

What are JPG files?

JPG is one of the most popular image file formats currently in use, often referred to as a standard for uploading images online and for displaying photographs. One of its main advantages is providing a good image quality in a relatively small file size, which is easy to store and transfer. JPG uses a type of compression that prioritizes the quality of some image sections over others, thus assuring that most favorable quality/size ratio.
