Learning to make Polygons in Google Earth

Today I am messing around and making KML and GPX files from our trip to Nigeria.

Reading: https://developers.google.com/kml/documentation/kml_tut#polygons and http://projects.visualstudies.duke.edu/isismapping/sites/default/files/isisguides/earthguide.pdf.

I hope to take some of our photos, a polygon of the language area, and our GPX route traces and overlay them on an Open Street Map page in WordPress.

The one thing I don't think is possible with GoogleEarth is to move polygons. I created them and then they were about a mile off, so I just wanted to move them... not possible. - to my knowledge.
