To do so, I used a combination of Illustrator, GoogleEarth, and Excel spreadsheets. Then I converted Illustrator paths to Apple Motion as explained in this post and animated.
Now with this ArcGIS Map add-on to Illustrator, I can skip GoogleEarth and instead import the spreadsheet inside the map console, and build / modify location markers directly inside Illustrator.
Building Maps inside Illustrator! Whoa!
Importing locations via spreadsheet! So easy!
Check this YouTube video for a demo on how to use ArcGIS inside Illustrator.
