- Abstract
- Environmental issues like deforestation are major challenges in the context of dry regions. To characterize this topic, we propose a new algorithm based on the unsupervised K-Harmonic Means classification algorithm and vegetation indices (VIs). The purpose is to optimize vegetation cover information mapping using Landsat images. The region of Mecheria in South-Western Algeria, classified as a semi-arid to arid area, is selected for experimentations. Moreover, two dates 1987 and 2019 are considered for a better assessment of the results. - The proposed methodology integrates multiple vegetation indices regarding their ability to extract vegetation covers in dry climate conditions. The classes presenting the highest correlation ratio are then combined in a quick yet ingenious way creating the final vegetation area. - The new combination technique, inspired from clustering ensembles algorithms, shows an average improvement in accuracy of 16.55% and 29.15% respectively for 1987 and 2019 classification results. These values were computed using confusion matrices. An additional assessment is conducted comparing the proposed methodology with established combination techniques using multiple criteria.
