Vol. 20 No. 1 (2026): Journal of Geomatics

The Journal of Geomatics continues to serve as a vital platform for advancing research at the intersection of geospatial science, environmental analysis, and sustainable development. The present issue 20, volume 1, April 2026 brings together a diverse collection of studies that reflect the growing significance of Remote Sensing, GIS, and data-driven approaches in addressing complex environmental and societal challenges.

A prominent theme emerging from this issue is the application of geomatics in understanding terrain dynamics and landscape processes. The morphometric analysis of Karanthaimalai Hill highlights how integrated GIS and Remote Sensing techniques can effectively characterize topographic variability, erosion patterns, and drainage systems. Such studies are crucial for informed land-use planning and environmental management, particularly in ecologically sensitive regions.

Urban resilience and disaster risk reduction also receive considerable attention. The assessment of flood vulnerability in the Chennai City Region underscores the pressing challenges posed by rapid urbanization, inadequate drainage infrastructure, and changing climatic conditions. By employing multi-criteria decision-making approaches and satellite data, the study provides actionable insights for sustainable urban planning. Similarly, the analysis of cyclone-induced land use and land cover changes in the coastal wetlands of Diu offers valuable perspectives on the environmental impacts of extreme weather events and highlights the need for climate-resilient strategies.

Heritage conservation through advanced geospatial technologies is another interesting study presented in this issue. The detailed UAV and GIS-based mapping of Rajgad Fort demonstrates how high-resolution spatial data can document and preserve cultural landscapes, bridging the gap between technology and heritage management.

Water resource management emerges as a critical focus area, with multiple studies addressing groundwater sustainability. Investigations in Hunsur taluk, Tirupathur district, and the Tiruchirappalli region collectively demonstrate the effectiveness of integrating GIS, remote sensing, geophysical surveys, and analytical hierarchy processes in identifying groundwater potential zones and planning artificial recharge structures. These approaches are essential for mitigating water scarcity and ensuring long-term resource sustainability.

The issue also highlights the increasing role of machine learning and artificial intelligence in geomatics. From temperature prediction in Ghana using advanced regression models to forest fire susceptibility mapping in the Hindu Kush Himalaya, these studies showcase the power of data-driven methodologies in environmental monitoring and risk assessment. The development of the Dhristhi Web-GIS platform further exemplifies innovation in democratizing geospatial technologies, enabling non-experts to monitor land-use changes effectively.

Ecological and agricultural applications are equally well represented. The estimation of above-ground biomass in the Thar Desert using multi-sensor satellite data underscores the importance of integrating SAR and optical datasets for improved accuracy in arid environments. Likewise, crop discrimination studies in Uttarakhand demonstrate the potential of machine learning and data fusion techniques in enhancing agricultural monitoring and decision-making.

Collectively, the contributions in this issue reflect the evolving landscape of geomatics, where interdisciplinary approaches, technological advancements, and data integration play a pivotal role in addressing real-world challenges. The studies not only advance scientific understanding but also provide practical insights for policymakers, planners, and stakeholders.

The editorial team extends its appreciation to the authors, reviewers, and readers for their continued support and commitment to excellence. We hope that the research presented in this issue will inspire further innovation and collaboration in the field of geomatics, contributing to a more sustainable and resilient future.
