Google Maps for Knowledge Elicitation

I'm experimenting with Google Maps "My Maps" drawing tools for knowledge elicitation. In this case, I'm specifically interested in knowledge elicitation for ground combat. My plan is to create a custom map someplace on the globe and use the drawing tools to draw up a combat situation using the MIL-STD 2525 notation. My Maps has very simple drawing tools, but I think with just lines, polygons and some custom icons like the ones below, I can do some interesting things.



Here's my second set. This time I made them a bit smaller, added red platoon icons and some icons to indicate that the red units are not visible. I also made the icons a standard size 50x50 pixels so that they line up better.



Here's an example of what you can get out of My Google Maps just using these icons and its standard drawing tools.



I'll write up my procedure and results soon.
