Compare maps

You need to enable JavaScript in your browser to be able to use this website.

After you enable JavaScript, reload this page and you can compare four different maps like you see below. Each map is displayed in it's own rectangle. Panning and zooming one map will pan and zoom the other three maps too. Like this, you can compare different features by panning them from one map to another and seeing how they change. Also you can move the red lines to reveal one map or the other and see how features change. Very easy to spot the differences.

Below are three snapshots to get an ideea about the interface. One is taken at country level, the next at continent level and the last shows the whole world.
