I hope this hasn't been covered already here. I did some searching, but didn't turn anything up.
I have a gps track formatted in kml (and I could probably massage it into a variety of formats or restructure the kml if needed.)
Basically I would like to animate a long track of gps points. I want to see this from a mostly top down view of the whole area. I want to start with a blank slate and then see the 2d points of the track appear one by one so that you can see the track build and develop.
I'm *not* interested in a "fly through" mode where I mimic the view from the vehicle. I'm not interested in manually manipulating the view and recording it as a tour.
I'd like to automatically re-play my track, have it start from nothing, and see it grow and develop over time -- while watching it from a fixed top down view that will contain the entire track when it is finished.
I've googled around quite a bit, and I see information that seems to indicate this (or something similar) is possible in google earth. But so far I haven't found the secret. I found a "whale shark" example online that supposedly plots the movements of a tagged whale shark. I can see the entire final path, but I can't get it to animate like the demo suggests it can.
Any tips for a google earth newbie?
For the particular case I'm immediately interested, we have a tracking buoy attached to some debris that has been floating around for a couple years in the north pacific. If you want to take a peek at the data I have attached a kml file. It contains roughly 2 position reports per day for the last 3 years and the drift path is really fascinating. I'd really love to make a movie of the motion and condense it down to maybe 30 seconds. I know this isn't exactly UAV related, but it's part of the same project where we are building a UAV to help find the debris in the first place. Here is a top down picture of the route. Junk that's floating in the ocean really gets around!
There is a program that does this in real time like gpsgate called earth bridge. check these out:
Hi Curt, would you mind explaining what you did? Can you post another sample file? Struggling with the same problem. Cheers, Chris
