How to use Google Earth as a trip planning tool with your Garmin GPS
You can find the latest version of my how-to here. This article summarises and expands on the CPD I led October 19, 2013 a the ACMG's CPD sessions in Canmore, AB. By Tom Wolfe (ACMG/IFGMA)

How to use Topofusion to make Topo Map (and other) overlays for Google Earth
When you open Topofusion you will see several default panes. The top pane is the map view. You can select the imagery represented here using the pull-down menu at the top right. There are dozens of options, the one that is most useful to us here is .Can/Aus 0.003. which is based on the NRCan Toporama 1:50k mapset (the latest dataset available from NRCan). If you prefer the 1:250k mapset then try .Can/Aus 0.006.. If you like the old NTS maps try selecting .MyTopo..
The bottom left pane is just a file explorer, which lets you browse and import .kml or .gpx files. This is cool because it.s a quick and easy way to locate the relevant map area. Once you.ve imported your track you can then right click on the track (bottom right pane) and select .Center Map on File.. This zooms to the area of interest. Now zoom out a bit until you get enough of a map for your area of interest.
Now, from the top menu click File > Export View. Check the box beside .Export .kmz to Garmin GPS. as well as .Tiled KMZ for specific map type.. In this box select .Can/Aus 0.003. (or whatever imagery you prefer) to select the type of topo map you want exported. You can also tweak the width and height parameters (for a larger or smaller map of a different shape/proportion centered on the screen view) as well as turn on/off UTM grid lines.
This creates a .kmz file, which packages the tiles and georeferences them for use in Google Earth. If you don't have a Garmin GPS attached it will prompt you to save the file to your hard drive -- which I prefer to do anyway. Open the resulting file in Google Earth, and presto!
This file is the complete .kmz file I used to demonstrate these various techniques at the ACMG's CPD in October 2013. It contains sample tiles for the Burnie Glacier area and Balfour Glacier area.
