Spatial data shares a number of similarities with time-series data in being a contextual data type. In fact, it is often possible for the spatial and temporal attributes to occur in various combinations of behavioral and contextual attributes. Such data is also referred to as spatiotemporal data. For example, in some applications, such as hurricane tracking, the contextual attributes are both spatial and temporal.
