Tasman Glacier Fly By

I have been revisiting Google Earth and Google Maps.  I have previously mentioned the plotting of wayside points in GM using icons and photos as icons to show the route of your trip  A manual plotting of points provides a good result if you can find where the photo was taken. Prior to GPS co-ords being included in cameras, this was the only way.  With GPS comes the GM import option. You can load a representative set of photos to your Google drive and create an album for them.
In Google maps you have a one time only option to import a set of photos to a newly created layer in your map.  Sounds fine in theory but the GPS does not always work at the time the photo is taken. Also the import never takes them in the order you have placed them in the album.

This has consequences for any FlyBy sequence you are trying to establish.  Once the map is set, with all waypoints, photos and captions in place the export option can be used to create a Keynote file for use in Google Earth.  The order of progression can be adjusted in the KML file by using a text editor like Wordpad.  Search for your first waypoint using either its caption or a GPS co-ord. Cut the text between <placemark> and </placemark>  and position it at the top without disturbing any other code. *Note to Google developers to incorporate the time taken field as a sorting method to preserve the chronological order.  After some time the file is now in order.  Import the file into Google Earth and save it to My Places.  Now the FlyBy can be run to show your tour.   I have prepared a short one below where I have tried a physical interaction which takes some practice to appear seamless. I used SnagIt to record the show.
