What is a DT2 file

DT2 files mostly belong to Global Mapper. DT2 files are used by different programs to store various kinds of data. They are not tied to a single function.
For example, one form of DT2 is a Digital Terrain Elevation Data file used in mapping and terrain analysis. This is typically handled by GIS software such as Global Mapper.
Another form serves as a dynamic theme or template file containing layout and style information for presentations. Such files are used by Microsoft PowerPoint (PowerPoint) and similar software.
A further use is as an image data file that may contain thumbnail previews or graphic content in formats like PNG, JPG, or even GIF.
There is also a version that stores seismic displacement time series data, which is used in seismic monitoring and analysis, for instance by databases such as the PEER NGA STRONG MOTION DATABASE (NGAWEST2).
FilExt.com tips: This file extension is versatile. The specific content and the method to open or view a DT2 file depend on which application created it. It is best to check the file’s origin or examine its header to decide if a GIS viewer, presentation software, an image editor, or a specialized analysis tool is required.

How to open a DT2 file

You need a suitable software like Global Mapper to open a DT2 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 DT2 file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a DT2 file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert DT2 files:

Global Mapper
See the previous paragraphs to learn more about the main application. DT2 files are often referred to as Global Mapper gis because this type of file is primarily created or used by this software.
DTED (Level 2) by National Geospatial-Intelligence Agency
A data file of DTED (Digital Terrain Elevation Data) is a cell defined by latitudes and longitudes of a geographic reference system. The terrain elevation information is expressed in meters. The locations of elevation posts are defined by the intersections of rows and columns within a matrix. The required matrix intervals, defined in terms of geographic arc seconds, vary according to latitude. DT2 is generally 1 arcseconds.

DT2 format details:

To find out what program is needed to open DT2 files, you need to determine the file format. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. So you need a detailed analysis of a file to find out the format and the associated program. Our evaluation of the DT2 files looks like this:

The DT2 file type includes various formats for various programs. The two most common formats are as follows:

45% of all DT2 files start with the bytes UHL1 crucial for this file format. They consist of unreadable binary data. A typical file size is 25 MB. The file type was developed 20 years ago and is still in use today. Certain words are almost always found in the files, such as DTED, USCNIMA, DSIUOOPUBLIC SALE/NO and RESTRICTION.
9% of all DT2 files save the data in PNG file format. PNG is short for Portable Network Graphics. It is a high-quality raster image file that supports lossless data compression. These files are binary files, so they do not contain text, but only cryptic characters. A typical file size is 20 KB. The following keywords are characteristic: IHDR, gAMA, sRGB, cHRM and IDATx. A usual file name is 2VdOiRn8R6vgyAo1OuWk82FGrO9g-.dt2. These files are often associated with fgro, ouwk and vdoi.

All the rest of the DT2 files (46%) have different formats, often, for example, GIF, CAP, JFIF, PEER and Siste. Files like these are sometimes linked to lomap, jnuepqvrp, impvall, ylfaol, zlcgrs, dvnzg, gwfhz, eenk or keyp. If you want to find out what your DT2 file contains, drag and drop it onto this page.

How to solve problems with DT2 files

Associate the DT2 file extension with the correct application.
Update your software that should actually open data files. Because only the current version supports the latest DT2 file format. Search, therefore, e.g. on the manufacturer website after an available Global Mapper update.
To make sure that your DT2 file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
