A method, computer-readable medium, and apparatus are provided for browsing maps of events of various types that occurred on a piece of land on various dates. A map is displayed on a map interface that allows a user to navigate to other maps using different types of navigation that are triggered by different types of user input. A single instance of a first type of user input triggers display of another map of the same event type as a currently displayed map. A single instance of a second type of user input triggers display of another map that is chronologically adjacent to the currently displayed map, regardless of event type. Alternately, the second type of user input triggers skipping maps of the same event type to navigate to a map of a different event type. The maps each include a graphical representation of a measurement at a given location.
