Abstract
Soil moisture estimation is a critical component of environmental management and agricultural planning. This review paper explores an extensive array of techniques and methodologies for soil moisture estimation, with a focus on the integration of Geographic Information Systems (GIS) and remote sensing. The review encompasses a spectrum of approaches, ranging from ground-based methods involving in-situ measurements, gravimetric techniques, and electrical measurements to advanced remote sensing technologies such as passive and active microwave remote sensing, optical and thermal remote sensing, and GIS-based integration. The comprehensive analysis includes detailed case studies that demonstrate the practical applications of these methods in diverse geographical regions and environmental conditions. As the world faces increasing challenges related to climate change and water resource management, accurate soil moisture estimation emerges as a vital tool. This review paper not only offers insights into the methodologies but also addresses the challenges and limitations associated with soil moisture estimation. It provides a valuable resource for researchers, environmental scientists, and policymakers working in fields where soil moisture plays a pivotal role in decision-making and resource allocation. The integration of GIS and remote sensing techniques presents a powerful approach for addressing the global demand for precise and timely soil moisture information in a changing world.
