Production of change indices

How to summarise changes of thematic properties?
There are many ways to describe change through indices. With this approach property change of individual spatial features is summarised with an index. This can account for an absolute or relative change, in an univariate or multivariate context. The following table presents various methods for the production of change indices.

Let us first differentiate between methods dealing with only 2 limits of time and those managing several discrete intervals.
