.GPX File Extension

Origin Of This File.

The .GPX file format was developed in the early 2000s as an open standard for GPS data interchange.

It was created to address the need for a universal format that allows GPS data to be shared across different GPS devices and software applications seamlessly.

The format was initiated by TopoGrafix, a company that specializes in GPS software and mapping tools.

File Structure Technical Specification.

.GPX file is essentially an XML (Extensible Markup Language) document that adheres to a specific structure defined by the GPX schema. This schema outlines the elements and attributes required to represent GPS data accurately.

Here are some key components of a .GPX file:

1. Metadata: This section contains information about the file itself, such as the name of the creator, copyright notices, and the software used to create the file.
2. Waypoints: Waypoints are specific locations marked by latitude, longitude, and elevation. They can include additional information like the name of the point, a description, and the date and time it was recorded.
3. Tracks: Tracks represent recorded paths or routes taken during a journey. They consist of a sequence of waypoints connected by line segments. Each track can have attributes such as name, description, and type.
4. Routes: Routes define planned paths or routes that may or may not have been traveled. They consist of a series of waypoints in a specific order and can also include attributes like name and description.
5. Extensions: .GPX files can be extended to include custom elements or attributes that are not part of the standard schema. This flexibility allows developers to incorporate additional data for specific applications.

The .GPX file format’s use of XML makes it highly readable by both humans and machines, and it can be easily parsed and processed by software applications.
