| Digital Line Graph Vector Image Format | N/A | GIS Files |
DLG is the file extension used for Digital Line Graphs, typically created using ArcGIS. Digital Line Graphs are vector graphics that use nodes (or coordinates) connected by lines and arcs to represent linear geographical features such as roads, rivers, elevation contours, woods boundaries, and military deployment zones. Digital Line Graph files can be imported into GIS applications like QGIS, DNR Garmin, or ESRI ArcMap, allowing users to view linear features as maps. In addition to representing linear features, some GIS software can use DLG files to produce 3D models of roads, coastlines, trails, and other ridge lines.
Other common file extensions related to DLG include .E00 (ArcInfo Export), .SHP (ArcGIS shapefile), .MIF (MapInfo Interchange Format), and .dem (Digital Elevation Model). Generally speaking, any digital vector geographic information created inside a GIS-like program can be stored in a DLG file.
Features and Use Cases
In the past, the use of DLG files was limited to viewing linear features or using them for analysis purposes in sophisticated GIS applications. Today, however, they are used extensively in recreational mapping applications such as Garmin Basecamp, TOPO U.S., or even mobile bike navigation applications.
The basic characteristics of DLG file format have remained largely unchanged throughout the years. It still retains the basic structure composed of nodes (or points) connected by lines and arcs. Additionally, the useful graphical accessibility to these lines make them intuitively understandable by both GIS professionals and recreational enthusiasts alike. This combination of versatility and accessibility make the DLG file extension an optimal format to preserve digital vector geographic details.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .DLG) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .DLG extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .DLG file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .DLG extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .DLG extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .DLG file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .DLG file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .DLG file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .DLG file) will be extended to the maximum.
It is also good to check
- if the .DLG file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
