Seasonal Dynamics of Coastal Landscapes: A Critical Review Using Remote Sensing and GIS
Abstract: Coastal landscapes are among the most dynamic environments on Earth, undergoing continuous transformation due to both natural processes and anthropogenic activities. In India, particularly along the southern coastal regions of Andhra Pradesh, Tamil Nadu, and Kerala, shoreline morphology and sediment transport patterns are significantly influenced by seasonal monsoons, cyclones, storm surges, waves, tides, and changing river discharges. These factors contribute to varying rates of coastal erosion, accretion, inundation, and land- …

Review of Agriculture Water Conservation Using Remote Sensing
Abstract: The operational usage of irrigation depending on frequent multi-spectral imaging data is supported by the experiences accumulated over the previous 30 years. The operational application of dense time - series data of multispectral imaging at high spatial resolution currently enables monitoring of agricultural biophysical parameters, recording crop water usage throughout the growing season, with adequate temporal and spatial resolutions. These developments enable precise estimates of agricultural water requirements with previously …

Correlation between Enhanced Vegetation Indices and Rainfall Patterns of Kurnool District, Andhra Pradesh
Abstract: Vegetation indices enhance vegetation spectral signatures by combining bands of red (630–700 nm) and near-infrared wavelengths (700–1100 nm). This can be best suited to study vital activity of vegetation on land surface. Kurnool district is chosen to assess the capability of continuous spatial and temporal coverage; MODIS-derived enhanced vegetation indices (EVI) data were utilized to monitor the vegetation seasonal dynamics and their relationship with precipitation. Statistical analysis of mandal-wise mean …

Integrated Geospatial Technology for Appraising Surface Temperature and Forest Biomass in Context to Conducive Tiger Habitats in Sariska Wildlife Reserve, India
Abstract: Sariska Wildlife Reserve of Rajasthan (India) is an excellent wildlife habitat, but due to improper conservation, anthropogenic activities and human-wildlife conflicts, the number of tigers started dwindling in the middle 1990s and completely disappeared during 2005. The forest temperature and forest biomass are vital parameters in several forest-related issues and has an apparent relationship to wildlife habitat and conservation strategies. Satellite remote sensing data being the best possible way for …

Optimization of Energy Efficiency in Multihop Cooperative Communication Networks
Abstract: Next-generation wireless networks use point-to- multipoint paradigms of classical cellular networks. They will be based on large interactions, where the involved nodes cooperate with one another in order to improve the performance of their own communication and that of the global network. Cooperative communications based on relaying nodes have a promising approach to increase spectral and power efficiency, network coverage, and to reduce outage probability. The concept of Cooperative Communication …

Real-Time Crack Detection in Polymer Composites Using Embedded IoT Sensor Networks
Abstract: This study developed an embedded Internet of Things sensor network for real-time crack detection, localization, and severity assessment in glass–fiber-reinforced polymer composites. Four polyvinylidene fluoride sensors were embedded near the laminate mid-plane and connected to synchronized wireless acquisition nodes. Controlled low-velocity impacts generated graded damage states. Ultrasonic C-scan and optical microscopy provided independent labels. A compact multi-channel convolutional model processed normalized waveforms, spectral entropy, signal energy, and arrival-time differences at …

GIS and Remote Sensing in Mapping Aquatic Vegetation, The Food Source of Waterfowl
Abstract: Carrying out time and cost effective field surveys has always been a great concern of ecological studies of a large spatial scale. We studied the possibilities to map the distribution of submerged aquatic vegetation in a shallow lake using satellite imagery. We also went further to investigate the relationship of the predicted biomass per creek and bird densities. The study was carried out with an IKONOS image of the Lauwersmeer …

Performance of Artificial Neural Network for Tree Species Identification using Sentinel-2 Data
Abstract: Accurate land cover mapping, especially concerning vegetation, is crucial for effective land use policy planning and sustainable forest management. Hence, achieving accuracy in mapping requires a deep understanding of composition changes, vegetation conditions, and the spatial distribution of tree species. In the spatial context of tree species, it holds significant potential for applications including invasive species monitoring, delineating contaminated areas, and biodiversity conservation. However, traditional methods for tree species identification …

A Comprehensive survey of robust image quality metrics for satellite imagery
Abstract: Satellite imagery is essential for applications like environmental monitoring, urban development, precision agriculture, defence surveillance, and disaster response. The reliability of these applications is closely tied to the quality of the captured images, which may be compromised by atmospheric effects, sensor imperfections, compression artifacts, and transmission noise. As a result, accurate image quality assessment (IQA) is essential to ensure trustworthy analysis and informed decision-making in satellite-based systems. The distinctive properties …
