Interactive Layers Map Example

An example of an interactive map that uses checkboxes to allow the user to select from a variety of layers to compare between them is the National Geographic Vital Statistics application - part of their Earthpulse program. The site lets users select from a variety of data topics regarding environmental science and human geography. While the map does not allow the user to position layers on top of each other as in a faux-GIS scenario, it does allow the user to switch between the layers through the use of a slider. That way, one can see the relationships between topics such as change in primary forest area and bovine consumption by country. Each data set has additional information on the topic displayed in the panel below the map space.
