Mapping support uses similar software to what I use. So in case your interested here is my map generator:http://www.acemaps.com
At the bottom of the screen there are two buttons for generating the map. The quality is best when zoomed into fully to the location you want. It takes about 30 seconds to generate the map. Once the map is generated be sure to right click for the image source and copy the url to get an even bigger map.
And then if you want to get even fancier I used picasa 3 with the I'm feeling lucky button for the map to make the contrast a little better. Then I used paint to draw out the map.
Perhaps some day I may figure it out, but I have topo display, and google earth display for browsing. Some day I would like to have it topo while in 3-d earth mode.
