Hi Frank: Thanks for the write up. As you say, GE makes it possible for each of us to take a look the earth's glaciers. You can't see everything from space, but it's great to have access to the things you can see. With glaciers, you can take an educated guess if they are retreating or advancing, but it's much even more valuable to have annotations about historical growth and access to overlay maps. I guess that's why I love this program so much.

You can get the raw data from NSDIC in the from of a spreadsheet. I have access to GE pro which allows one to import lists of placemarks organized as a spreadsheet. The import wizard makes it very simple to create a set of placemarks from a resonably organized spreasheet. The only real requirements are that you need to have columns with lat, lon and a name. Optionally you can even set the color of the placemark from a column.
