Technical note

DT1 to JPEG: what to expect from the conversion

Every cell in a DT1 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. JPEG 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 JPEG returns a shade, not an altitude. DT1 carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. JPEG has nowhere to record any of that. The picture transfers intact, the location does not, so the output cannot be dropped onto a map afterwards without being placed by hand. Keep the DT1 original if the data still has to go back into a GIS.

Map Data Workflow

Turn GIS data into something anyone can open

Not everyone who needs to see DT1 data has GIS software. reaConverter renders it to JPEG for a report, an email or a slide, and handles a whole folder in one run.

  • Render every file in a folder to JPEG 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.

FAQ

DT1 to JPEG Conversion

What are DT1 files?

DT1 is the file extension for Level 1 of Digital Terrain Elevation Data (DTED), a standardized elevation product described in the MIL-PRF-89020 specification of the U.S. National Geospatial-Intelligence Agency (NGA). Each file represents a one-degree by one-degree geographic cell and contains terrain heights sampled at a regular interval of 3 arc-seconds, equal to approximately 90 to 100 meters at the equator. Level 1 sits between the coarser Level 0 (.dt0) and the finer Level 2 (.dt2) products, and serves as a common choice for regional terrain analysis, flight planning, line-of-sight studies, and mapping at medium scales. The file starts with header records that identify the cell, its origin, and its accuracy, followed by the matrix of elevations. The format is a long-established standard in defense, aviation, and civil geospatial work.

What are JPEG files?

JPG or JPEG is a commonly used method of lossy compression. JPEG compression is used in a number of image file formats. JPEG/Exif is the most common image format used by digital cameras and other photographic image capture devices; it is the most common format for storing and transmitting photographic images on the internet.
