This set of maps are developed in order to communicate changes in polar ice cap coverage. The maps illustrate a series of frames that show changes in ice cap coverage every year since 1979. The interactive tool provides a simple interface, consisting of the map images, a scroll bar, and a play button. There is also an animated bar graph at the bottom of the screen which gives a relative comparison between different years.
These maps are a very simple example of a chain of different maps animated in sequence. Each map here is developed as a frame in the animation. Here, the design relates interestingly to the subject matter – the icy white of the interface relate very closely to the subject matter of melting ice caps. To string together the images, an iframe with a jQuery control was used.
