What is a .GPN file?
The file extension .GPN is associated with a type of file known as a GlidePlan Map Document. This file is created by a software called GlidePlan, which is used for pre-flight planning by pilots and aviation enthusiasts. The main purpose of a .GPN file is to store a map that is useful for flight navigation.
The content of a .GPN file includes a reference or pointer to an aviation map that is typically a rasterized image saved in the .JPEG format. This JPEG file is a digital version of an FAA Sectional map, which is a type of map specifically designed for aviation use, showing airspace, airports, and other navigational details.
In addition to the map itself, a .GPN file contains additional data that is used to overlay various graphical elements on the map. These elements might include routes, waypoints, or other important navigational information that helps pilots plan their flights more effectively.
To open a .GPN file, you need to use the GlidePlan software. GlidePlan is specifically designed to work with these files, allowing users to view the detailed maps and make use of the overlay graphics for planning their flights. There is no mention of other programs that can open this file type, so GlidePlan is likely the only software capable of properly handling .GPN files.
