DGG File Extension

Have a problem opening a .DGG file? We collect information about file formats and can explain what DGG files are. Additionally we recommend software suitable for opening or converting such files.

What is the .DGG file type?

The .dgg filename extension primarily represents the PLZ-Diagrammvorlage (PLZ-Diagramm Template, .dgg) file type used by Das PLZ-Diagramm, a German-language ZIP-code area charting application developed by Klaus Wessiepe for Microsoft Windows and distributed as shareware. Regular Das PLZ-Diagramm charts are saved as .dgr files, while area templates (Gebietsvorlagen) receive the .dgg extension. Referring to Das PLZ-Diagram, the .dgg file represents a template of a charted area arranged to follow the existing territorial division based on ZIP codes, dialing codes, or other criteria. Such .dgg templates define area shapes and borders and provide a ready-made basis for user charts. Just like regular charts (.dgr), it is a formal XML document readable and modifiable by the program. The source code of any .dgg file can be viewed by opening the file in a text editor. Several sample templates (.dgg) are provided with Das PLZ-Diagram in the "%ProgramFiles%\Das Postleitzahlen-Diagramm 3.8\Vorlagen" folder, covering dialing codes, administrative land divisions, etc. for Germany and other German-speaking countries.

Quite apart from the above, the .dgg extension also serves to denote GPS + GLONASS radio-frequency (RF) signal recordings made with a Spirent RF recorder like GSS6450. Here, the .dgg file provides a container for the waveforms of both GPS (13 MHz) and GLONASS (26 MHz) high-frequency radio signals captured from the air.
