What is a DT0 file?

DT0 files mostly belong to DTED Elevation Extractor. DT0 files are used mainly as Digital Terrain Elevation Data files. These files store elevation information for mapping and geospatial analysis.
They typically come in two forms:

Digital Terrain Data: This is the primary use, where the file holds topographic information intended for use with GIS software and specialized viewers such as the DTED Elevation Extractor. The data helps in understanding land contours and elevation changes.

JPEG with Metadata: Some DT0 files may contain JPEG images with embedded metadata. These use the JFIF format and are generated by tools like the Intel(R) JPEG Library, making them openable in standard image viewers if the embedded metadata is recognized.

For more details on the terrain elevation aspect, refer to the GeoComm website.
FilExt.com tip: If you have a DT0 file, first check its content structure. Use a GIS or a DTED viewer to examine terrain data, or if it appears as an image file, try a regular image viewer.

How do you open DT0 files?

You need a suitable software like DTED Elevation Extractor to open a DT0 file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your DT0 file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a DT0 file directly in the browser:. Just drag the file onto this browser window and drop it.

DT0 file format:

Each file has a definite file format, that is, how the stored data is arranged in the file. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. Exact knowledge of the format is therefore important in order to solve problems occurring in files. In the following you will find our evaluation of the DT0 files:

DT0 is not a common file extension and includes different formats for the applicable programs. However, the following two file formats are common:

• 30% of all DT0 files are Digital Terrain Elevation Data files. The content consists of illegible binary data, which can only be read and interpreted by the associated programs. The files are often between 18 KB and 34 KB in size. The file type was used 20 years ago. Several words can almost always be found in the files, e.g. DSIU, DTED and USNIMASL. n31.dt0 or n04.dt0 is a typical file name.
• 9% of all DT0 files are using the well-known JFIF file format to store the data. JFIF is short for JPEG File Interchange Format. It is a bitmap graphic that uses JPEG compression. These are binary files, so they do not contain words or text. A typical file size is 130 MB. The keywords $.' ",#, '9=82<.342, (7),01444, JFIF and *Intel(R) JPEG Library, version 1,5,4,36 are typical for these files. A usual file name is 20180601.DT0.

All the rest of the DT0 files (61%) have different formats, the following 4 formats can be found: NUMERO. These files sometimes refer to role. If you want to find out what your DT0 file contains, drag and drop it onto this page.
