space-time cube: based on work by Hägerstrand on time geography, where locations are represented on the x and y axes and the z-axis is reserved for representing the temporal attribute.

#Mapping time cartographica series

small multiples (chess maps): a series of static maps that show spatiotemporal data at various time stamps.

rate of change:the rate at which an animation plays through the scenes.

ordinal time: time as relative, ordering events in relation to one another.

mental interactivity: an affordance of small multiple maps that allows the map reader to visually compare the spatial pattern differences between different snapshots.

magnitude of change: how much change takes place across the display during one scene transition.

locational change: expansion, contraction, and movement of objects.

linked views: a dashboard-type view with both statistical graphics and maps where the component graphics are linked and the map user can brush over locations in the display to see corresponding connections between the data illustrated in each pane.existential change: the appearance or disappearance of events or objects.

duration of scene: how long each scene in an animation is displayed for viewers.

dance map: locations of events and the transitions between are symbolized.

cyclic time: time as reoccurring time entities such as hours in the day, days of the week, and months in the year.

congruency principle: the ability of some graphics to represent abstract concepts that are cognitively suggestive between cognitive space and real space in terms of time, this means using display time to represent time as is possible through the use of animation.

change maps: maps that illustrate the difference between two time slices by subtracting the older time slice from the newer.

attribute change: changes to the character or quality of an event or object change over time.

animated map: a map that uses display time to illustrate change in location, attributes, or existence over real time.

Cartographic Decisions for Representing Spatiotemporal Data.

Mapping Time in Cartography and Visualization.

Introduction to Spatiotemporal Representation.

This entry focuses on the mapping of time and spatiotemporal data, the types of time, current methods of mapping, and the advantages and limitations of representing spatiotemporal data. However, each of these different mapping techniques offers its own advantages and disadvantages to the cartographer and the map reader. For cartographers, identifying the audience and purpose, medium, available data, and available time to design the map are vital aspects to deciding between the different spatiotemporal mapping techniques. The advantages and limitations of these static and dynamic methods are discussed in this entry. Four broad types of mapping techniques allow for a variety of representations of spatiotemporal data: (1) single static maps, (2) multiple static maps, (3) single dynamic maps, and (4) multiple dynamic maps.

Cartographers and geovisualization experts alike have grappled with how to represent spatiotemporal data visually. There are many ways in which to conceptualize space and time in the geographic realm that stem from time geography research in the 1960s. Space and time are integral components of geographic information.
