usually good quality data available and easy to calculate
Necessary default stimulation direction of indicator shows need for water retention
Possible default stimulation direction of indicator shows possibility for water retention
Remember to always choose both types of indicators that represent needs and possibility
Please choose the number of classes and if needed adjust their ranges. Changes in the direction of influence (stimulation or not-stimulation) of the indicator value on the need for water retention should be done only in exceptional situations. Changes in the weight are recommended if a clear dominance of one group of indicators, eg concerning LandUse was observed, then you can reduce their importance by changing the weight.
