Doarama changed name to Ayvri, and appears to be very “pay-to-play”.
I uploaded a sample KML-turned-GPX file from Lovers Leap turnaround to Lovers Leap Camp, and got a non-intuitive animation player that seemed to only allow adjusting the time and play-back speed. I was also able to zoom in and out. I did not manage to find a way to manually change my viewpoint over the terrain.
The terrain looked nice, but the utter lack of info and paywall turned me off completely.
There are well-documented tools that still work with/in Google Earth Pro, which has been free for several years now.
“CesiumJS” appears to be the “new hotness” in 3D globe visualization, but I haven’t tried using it – yet..
There is a beautiful NASA -developed tool called “World Wind” that I toyed with a few years ago. It is for programmers and NOT consumer friendly/ready.
Accumulating the trails info in a user-friendly and multi-platform arrangement is the log-jam to being able to make your animations “quick and easy”. As I said here or the other digital file thread, the PSR-supplied file is “the gospel” if you want accurate distances and placement. But the trails are in small segments with wonderful names like “1.1357289”.
If you aren’t worried about every inch of distance, tracing trails in CalTopo and giving them a name that you understand like “Lovers Leap to Miners Park” will give you “good enough” trails to view in Google Earth or other visualizers.
Someone comfortable using Garmin and other GPS software can grab the Philmont data at “GPS File Depot” mentioned here or in the other thread.
