Description
The IB indicator represents the degree of Intensity of the Building located in low areas below current 100-year sea levels (ZBNM100). Unlike the IBC indicator, this indicator does not take into account the parameter "natural disasters of marine origin".
The cartographic representation of this indicator is discretized into 6 classes according to an algorithm using the average of each class to distribute the data in all classes in a balanced way. A 7th class has been added (value class 0). It corresponds to municipalities with no buildings in low-lying areas. The distribution of the IB indicator values for the ZBNM100 is as follows:
* Class 0: value IB [0;1[
* Class 1: value IB [1;20[
* Class 2: value IB [20;110[
* Class 3: value IB [110;320[
* Class 4: value IB [320;770[
* Class 5: value IB [770;2150[
* Class 6: value IB [2150;5940[
