 This example shows how to perform a single classification of pools and roofs through rule-based classification.
-This project is called "rule_based_classification" and uses the Tow Down operators //TerraAIDA_Baatz_Segmenter// and //Dummy Top Down//, and the Bottom Up operator //Generic Bottom Up//.
