Example: Converting to X3D format for 3D visualization

If you want to visualize tracklog data using a 3D modeling tool (such as Blender), you can convert a GPX file to X3D format using the following command:

GPSMash.exe -loadgpx file.gpx

-scale ele 10

-transform ortho

-normalize

-outx3d file.x3d

 

First, the GPX file is loaded using the -loadgpx file.gpx command. Next, the elevation is scaled 10 times (-scale ele 10) and the track is projected to a flat plane (-transform ortho); the result is exported as x3d file (-outx3d file.x3d). The X3D file can be imported to various 3D modeling and visualization tools.
