There are various ways of handling and representing time. Time is often described as the 4th dimension of GIS (especially in Time-Enabled GIS (TGIS)).
• One such model for representing time is the time slice model.
• Ideally, data such as time should be interactive and not be restricted to animations (which restrict longevity).
• Timelines are also very common representations of time.
• ‘Points’ are often used to represent ‘Events’ even though they actually have ranges. Everything can be potentially represented as an event.
• Animated raster images are often used to represent long-term changes (like rising sea levels).
