Open DTM File

DTM files are primarily associated with three different types of data formats: Digital Terrain Model files for geographical data, GIS software files, and DeLorme software files for mapping purposes. This article will explore the various utilities and ways to open and use DTM files for each of these formats.

Digital Terrain Model Files

A Digital Terrain Model, or DTM, is a 3D representation of a terrain's surface, usually used in geographical information systems (GIS) and civil engineering projects. These files typically consist of a matrix of elevation values, which are used to create a 3D surface model. Common formats for DTM files include .dtm, .dem, and .ter. Some of the most popular software programs that can read, display, and manipulate DTM files are Global Mapper, ESRI ArcScene, and QGIS.

Global Mapper (https://www.globalmapper.com/) is a powerful GIS software application which offers comprehensive support for DTM files. This versatile program enables users to view, edit and convert DTM data, along with integrating it with other datasets or exporting it in various other file formats. ESRI ArcScene (https://desktop.arcgis.com/en/arcmap/10.3/tools/3d-analyst-toolbox/what-is-arcscene-.htm) is another powerful 3D visualization and analysis tool used for working with DTM files. Lastly, QGIS (https://www.qgis.org/en/site/) is a popular open-source GIS software that supports DTM files and provides a wide range of geospatial services.

GIS Software Files

Besides Digital Terrain Model files, the DTM file extension can also be used by other GIS software, such as Intergraph's GeoMedia and the Bentley Systems' MicroStation software. These programs may use the DTM file extension for their digital mapping projects.

Intergraph GeoMedia is a popular GIS software suite for managing and analyzing geospatial data (http://www.hexagongeospatial.com/products/geomedia-overview). Users can import and export DTM files and other geospatial file formats and create custom mapping solutions. On the other hand, Bentley Systems' MicroStation (https://www.bentley.com/en/products-brands/microstation) is a powerful, versatile, and widely-used CAD software for 2D and 3D design projects. In addition to processing DTM files, it supports many other geospatial file formats.

DeLorme Software Files

DeLorme is a developer of mapping software, best known for its Topo USA and Street Atlas USA products. Within these applications, the DTM files are used for storing detailed map data such as elevation and transportation information. DeLorme mapping software is now owned by Garmin, and the company's website offers information and download links (https://www.garmin.com/en-US/software/).

DTM File Important Information

Before working with any DTM file, it is crucial to identify which of the mentioned formats the file belongs to. This can be done by checking the application or software that generated the file or by examining the file content. Identifying the right file type will help users determine the best way to open and edit the DTM file. It is also worth mentioning that if you experience issues opening a DTM file, it may be corrupted, or the software might not be compatible with the specific format.

In conclusion, DTM files are versatile and can be used with various GIS and mapping software programs. Understanding each format and associated applications will allow users to successfully open, view, and modify these files. Always use reliable and compatible software for your specific DTM file format to maximize productivity and minimize data loss or corruption.

How Can I Open DTM File on Windows

We researched and learned that the best way to open DTM file is to find a DTM file in question in Windows OS File Explorer and double click on it to launch the corresponding application.
If a DTM file is not opened in an application and you instead get a "Windows can't open a file" error message you should try looking for an application which can open the file in question.
If you know the application which can open DTM file then run it and see if there is a File->Open main menu option in the application.
If you don't know the application which function as DTM file opener then try to search online for "DTM viewer", "application to open DTM file" or "open DTM file" queries in the search engine you like.
Install the application you found and check if it can open DTM file

How Can I Open DTM File on Mac OS

We recommend to find a DTM file in question in Mac OS Finder and double click on it to launch the corresponding application.
If a DTM file is not opened in a Mac OS application and you instead get a "There is no application set to open the file" error message you can click on "Search App Store" in the error dialog and Mac OS will show you applications compatible with DTM file.
If you know the Mac OS application which can work as DTM file opener you can choose the "Choose Application..." option in the error box to associate the file extension and open DTM file in it.
If you don't know the application which can open DTM file then try to search for "DTM viewer", "application to open DTM file" or "read DTM file" queries in the online search engine you like.
Install the application you found and check if it can read DTM file

How Can I Open DTM File on Android

If you downloaded a DTM file on Android device you can open it by following steps below:

In the Android apps list on your Android device find "My Files" or "File manager" app and tap to start it.
Tap on "Downloads" folder inside the app.
You should see your downloaded DTM file in that folder.
Tap on the file. If Android device supports opening the file you downloaded it will open in the corresponding app.
If file does not open you can look for the corresponding app that can open the file by searching Android App Store for the "DTM".
If you cannot open the file with the apps from Android App Store it is possible that the file could only be opened on desktop platforms such as Windows or Mac OS. Try searching for "DTM viewer", "DTM file reader" online and see if any desktop applications can open it.
It is also possible that the file you downloaded is outdated and is no longer supported.

How to Open DTM File on iPhone or iPad

To open DTM File on iOS device follow steps below:

We advies to open Files app on your iPhone or iPad device. You can find it by swiping down on the home screen and typing "Files" in the search bar.
Tap on the Downloads folder on the Files app home screen.
You will see all files that you recently downloaded. Tap on the DTM file to view it.
If you have the right app that can open it it will automatically launch and open your file.
If you don't have the app which can open it you need to serch Apple app store for "DTM". This way you can find apps which can open DTM files.
If this doesn't help it is possible that your file could be opened only by the desktop application. To find an app which can open it on desktop look for "DTM viewer" or "DTM file" online in your favorite search engine.
