I am using the Google map overlay and I have finally figured out how to lay up to 4 miles of straight track which will match the Google map-lay image. I have the the DEMs installed. My challenge, right now, is to maintain the track to be accurate with the DEM elevations on my line. Is there a possibility of resetting the rail length to feet instead of meters? If not, then when I look at the rail height in the bottom right is it in actual meters?
