Track Height Data Problem Solved! - Now in Beta!
Hello all,
I just finished coding a program that will take a KML file that you make using the path function in Google Earth and update the altitude data automatically.
As a test, I used U.S. Highway 6 over the Loveland Pass in Colorado. I was so impressed with the drive many years ago and thought it would make a great track. Loop through the Eisenhower tunnel, up and over the Loveland Pass and back through the tunnel. But for the test, I just ran from the eastern tunnel exit and up to the top of Loveland Pass.
With this run, I had to manually transfer the coordinates data to the original KML file, but before I release it to beta, this will be done automatically.
I also noted that I had some fairly large altitude changes in about 5 spots. Between 5 and 10 feet within a 5 or 10 foot section of the track. I will create a routine and give the user the option to smooth the altitude data in these cases.
I am trying to keep the program as light as possible, so none of the data is written to temporary files and the program does not use any databases. All of the coordinates data is read into memory and processed from memory and the final extraction will be written to a new KML file for use in BTB.
For the Loveland Pass test, running from the development environment, it took just about one minute to cycle through all of the data and write the data to a file.
I fired up BTB and imported my new KML data. It took less then 10 seconds for BTB to pull in the data and present me with my track. I went to one section and added a bit of terrain and grabbed a screenshot.
I will advise when BTBHD (Bob's Track Builder Height Data) program is released to beta and I hope this will help contribute to the community... because I'm a horrible artist and I can't do 3D modeling to save my soul!
