Is it possible to do something like I'm doing with Trim Paths on the static map, but also do it for the track on my GEP satellite tour, and somehow have the track remain attached to the right place on the GEP satellite map as the map moves around and changes orientation and camera angle?
if there is enough perspective data, you can track it in Ae or other tracking software and attach the information to the graphics. since Ae is 2D and not real 3D, you may have to get creating with the orientation part and maybe keep the infographics as 2D hovering over as the camera spins. it would be easier to help you if you upload the exact video you are trying to process, and the exact reference you are referring to.
Okay, in an effort to flesh this out a bit:
Here is a short video clip of what NBC is doing. I am trying to accomplish the very same thing they are doing with the Google Earth part, on the right side of this video. I already have the two insets/overlays on the left side of the video worked out.
Here is a short video clip of what I am getting out of Google Earth Pro when I create a tour and movie from my hiking track. Note, there is no way to determine where I am on the track.

you got 2 main ways to approach this:
1. export a high resolution map from google, and use Ae for the hover animation using a virtual camera. this is what I do most of the time. Pros: full control over your animation, simple setup; Cons - no real topography or real cool parallax 3D'ness of your map.
2. export a video from google, and use the 3D Camera tracker to track it, or mocha on various planar grids if possible. then create your graphics and attach it to the track by setting it's 3d switch or to a null and placing it properly.
I am pretty sure NBC did not use After Effects for this type of enhanced sports graphics, these stuff usually are created using a special hardware and software like Viz.
I would capture your google earth footage on at least a 4K monitor using a good screen capture program. Then I would stabilize the motion so the google earth move goes away. You may need to motion stabilize scale and rotation. If the start of the path moves off the screen after stabilizing then put a layer marker on that frame, delete the keyframes to the right, then start another track so you can splice the moves together.
Then I would draw your race path using the pen tool, animate using trim paths, then add a null, name the stabilized footage "stabilized" and use this animation preset on the null.
After you have applied the preset to the null move the CTI to the start of the Motion Stabilize keyframes in the 'stabilized' layer and parent the footage and the path to the null.
The animation preset links the anchor point of the stabilized layer to the position property of the null and uses a little math on scale and rotation to remove the stabilization from the original layer and add the motion to the path.
This will give you a very close duplicate of the examples you provided.
I am not sure that AE's camera tracker would generate a good track because google earth uses an orthographically rectified images to recreate it's google earth maps and translates that into a spherical map. There probably isn't much real perspective and parallax change available in the image to calculate and replicate a real camera.
Depending on the shot you may be able to use Mocha's corner pin tracking to get what you need. My technique for that would be a modified version of this tutorial. It is a very good way to handle some pretty extreme perspective changes and lock a graphic or replace something in a shot that would be would be difficult to do with other techniques.
I hope this gives you some ideas.
Thanks for the suggestions Roei and Rick. I do appreciate your time.
Your suggestions give me some options to think about and play around with. Also looking at one other possibility in GEP.
Hopefully, I can come up with something that looks reasonably good that I can live with.
