Google Earth - Complete US Air Routes
A couple of weeks ago I put together a small collection of Google Earth airline route maps for various countries. These work interactively, using mouse hovers over airport Icons to activate and reveal destinations.
The previous files each had fewer than a thousand routes, and were fairly limited in scope. So, I was wondering, how effectively do these scale up ? As it turns out, surprisingly well.
The following Google Earth networklink opens a file including 13287 scheduled routes within the USA, between 714 airports.

Data is from the US Bureau of Transportation’s most recent monthly flight stats: October 2007. Strictly speaking it’s not really a route map in the same way as my other files - rather, it’s a map showing where scheduled airlines flew that particular month.
- Because of the high number of placemarks and long distances involved, this all looks much better full screen [F11].
- To permanently lock on a set of lines:
- Right click on the entire file, a folder or airport,
- Go to Properties,
- Select the Style, Color tab,
- Then increase the line opacity.
- Hit OK.
- The only way to fully reverse this, and get the mouse over effect back, is to re-download or re-open the file. To do this within GE: right-click on the root folder: US Flight Maps, and select refresh.
- Don’t forget you can hold down the middle mouse button and swing the view around while keeping the flightpaths displayed.
