Abstract

Ditches are important components of hydrological ecosystem and play a critical role in capturing and removing the micro-organisms and pollutants from water body. The generalization of ditches supports the multi-scale analysis and modeling of hydrological and ecological environment that relate to ditches. This paper proposes and implements a new method that combines two clustering ideas for typification of ditches. This method groups the ditches based on the edge-cutting of the minimal spanning tree of ditches, and represents the ditches in each group based on K-means++ algorithm. This study also presents the validation of the method with the experimental data of Guangzhou city.
