How big is France ... really?
This site lets you create an outline of one part of the world and overlay it on another place. For example, you can sketch an outline of BC in the "Reference Map" section, and then overlay the outline on Japan in the "Comparison Map." (Whatever outline you draw in the top map stays centered in the bottom map.)
You can use this page to answer questions like these: How big is Vancouver compared to my home town? How big is BC compared to France? If I put the Lion's Gate Bridge in my neighborhood, what landmarks would it overlap?
Note: If you draw the outline at one latitude, and then view the outline at a different latitude in the Comparison map, the relative orientation of the marker positions will be distorted.
