Monitorinf of permanent grasslands using syntetic Aperture Radar (SAR) coherence and intensity bands composition

Abstract

This paper presents a study analysing the performance of Synthetic Aperture Radar (SAR) satellite images, specifically their coherence and intensity bands, for monitoring permanent grasslands. An analysis over a five-year period, based on annual SAR image compositions, allowed the validity of this method to be assessed. The exceptionally high accuracy rates – 95.8% precision, 97.1% recall and 96.5% F1 value – confirm that SAR satellite imagery is a highly reliable tool for consistent monitoring of permanent grasslands. The high accuracy rates confirm that SAR satellite images are highly reliable data for continuous monitoring of permanent grasslands.
