Assessment of Urban Heat Island (UHI) in Bengaluru Using Earth Observation Datasets.

Rapid urbanisation causes several issues, including the Urban Heat Island (UHI) effect, where urban areas experience significantly higher temperatures than their rural surroundings. This is due to several factors associated with urbanisation, including the replacement of vegetation with buildings, roads, and other impermeable surfaces that absorb and retain heat. Additionally, heat emissions from industries and vehicles also contribute to the …

Flood Inundation Modelling

Flood inundation refers to the submergence of land areas due to rising water levels during extreme weather events, such as heavy rainfall or overflowing rivers. Accurate mapping of flood-prone areas is crucial for disaster preparedness, emergency response, and effective damage assessment. By predicting which regions are most likely to be inundated, authorities can develop early warning systems, plan evacuation routes, …

Land Use/Land Cover(LULC) Classification with Semi-Supervised Learning

INTRODUCTION Land Use Land Cover (LULC) classification is a vital process in remote sensing and geographic information systems. It categorizes Earth’s surface based on physical cover (e.g., forests, water, buildings) and human usage (e.g., agriculture, urban development, conservation). For instance, an area may have a land cover of ‘grass’ with a land use of ‘park’ or ‘golf course’. This classification, …
