Abstract

The Modifiable Areal Unit Problem (MAUP) is a well-known issue related to the influence of the spatial support on statistical observations. It occurs when different spatial units making different spatial partitions are used and when the resulting measures vary according to those partitions. In this paper, we first draw a state of the art. Considering the particular problem of (up)scaling, we propose a method to visualize the sensitivity of the spatial statistics to the support. We test this method on forest fires in Southern France, handling a sample from the Promethée database.
