Ocean and mountain features
While there is no direct vertical mapping between the parallel displays, it is roughly analogous -- each cutaway moves across the globe from left to right, while snaking up and down to hit different features. Labels repeated on the cutaways and the map above help link the parallel displays together.
Another juxtaposition affords comparison between elevations of different oceans and mountains: by looking left and right we can compare the depths and heights of different features from different parts of the globe. Also, certain landmark features are reproduced below others on the cutaway, an additional juxtaposition.
The selection of the cutaway is fixed, and the relationship between the cutaway and the map could be stronger. Both of these problems could be fixed with an interactive juxtaposition, one in which the cutaway lines were drawn on the map and could be manipulated by the user. The user could then choose what parts of the map to cutaway, and the relationship between the cutaways and the map would be strengthened by the indicators and the user's manipulation of that relationship, since the linkage would become "real through use" (Murray 1987).
