A Critical Assessment of High-Resolution Satellite Imagery for The Purpose of Extracting Water Body Areas

Abstract

The property of water plays a crucial role in various aspects of daily life, including urban planning, commerce, industry, and agricultural production and so forth. The assessment of water bodies and accurate distinction of their characteristics is crucial for effective planning, particularly in regions such as India where land areas are predominantly occupied by water bodies. When capturing satellite imagery, there are instances where certain features, such as the shadows of prominent structures, do not accurately depict the distinct characteristics of water and non-water areas. The photograph of the water body was significantly disrupted by the presence of a skyscraper's shadow. This disturbance is noteworthy due to the disparity of the tranquil water surface, which promotes reflective properties, and the occurrence of wave echoes. The cost of water delivery can be relatively inexpensive. The potential for significant benefits to India's national development lies in the effective implementation of water transportation. The establishment of a connection between multiple territories involved in the transportation of water necessitates the usage of an appropriate navigational instrument. Hence, it is imperative to provide a concise delineation of the tranquil surface of water compared with the interplay of shadows cast by residential structures. In recent years, there has been a limited amount of research conducted to analyse the characteristics of the water system using a large number of multi-spectral satellite images. The primary objective of this paper is to advocate an effective approach for water body extraction using satellite imagery through the application of computer-based remote sensing techniques using PC television for laptop remote sensing. The Geographic Information System (GIS) and the Global Positioning System (GPS) have been acknowledged for their significant relevance to the field of remote sensing. Initially, there was a significant focus on conducting research related to water frame detection. Several methodological challenges associated with the utilisation of these techniques have been examined and identified through the analysis of summaries. The study presents the outcomes derived from empirical studies, specifically utilising water-frame extraction techniques. These consequences are systematically gathered and duly referenced.
