4D GIS and Prediction

For the last two decades, GIS technologies have increasingly been used to incorporate not only spatial relationships but also analyzing and visualizing space across time. Spatial-temporal GIS, or 4D GIS, has, in particular, become essential in areas where GIS is needed for predicting dimensions across time.

The easiest way to show spatial change over time: side by side maps each showing a slice of time.

Time and GIS: Ways of Representing Time on a Map

Spatialtemporal visualization are ways to illustrate changes in an area over time on a map. The famous geographer Immanuel Kant maintained that geography was the study of knowledge in a location, while history was the study of knowledge in time. This article explores different cartographic methods of showing changes in time over space on a map.
