As we mentioned yesterday with the Virtual Watervliet, Google Earth can be a great tool to help visualize events from the past. Today’s example from MyReadingMapped goes back to Biblical times to show a handful of events including Moses parting the Red Sea.
Because of the way the Google Earth handles water, “parting” the Red Sea proved to be difficult. They handled that using the following methods:
The Sea Floor Path:
• First, using the Polygon tool while looking down, I drew a rectangle for the path that was to be my sea floor.
• While still selected, I assigned a color and an Altitude set to “Clamped to sea floor.”
The Walls of Water:
• I drew two paths from one shore to the other, making sure they don’t touch the shore, assigning the color, and the Altitude set to “Relative to the sea floor” with a altitude of 30m and “Extend path to ground” selected. For some reason “Extend to sea floor” did not work correctly.
• Next, I had to go back and refine each path to ensure it sat on the edge of the sea floor path.
It was a very creative way to tackle this problem, the results came out rather well. You can grab that KML file here and I encourage you to read their entire post on MyReadingMapped.
