Topobathymetric survey for calculations of elevations x areas x volumes and reservoirs using RPAS with on-board lidar sensor and single-beam echo sounder

Abstract

Advances in technologies and increasingly modern equipment such as RPAS, GNSS, LiDAR sensors, and ECOBATIMETERS have revolutionized topography, providing more advanced and effective tools for collecting, analyzing, and representing data, enabling a more precise, efficient, and versatile approach to geospatial information collection. These technologies have broad applications, and in this study, we present a methodology for topobathymetric survey development using RPAS and LiDAR, an advanced approach that provides detailed and highly accurate data for calculating elevations, areas, and volumes of reservoirs. This technique represents an effective and efficient solution for monitoring and managing water resources, meeting the demands of reservoir operating companies and environmental agencies.
