LiDAR technology is a powerful remote sensing tool that is increasingly being used for various applications, including building height extraction. Building height is a critical parameter for urban planning, infrastructure design, and disaster management. LiDAR data can be used to accurately estimate building heights and derive important parameters such as building volumes, roof shapes, and more.
Building footprints can be used for a variety of applications, such as urban planning, infrastructure development, and disaster response. For example, the footprints can be used to estimate the population density of an area or to identify areas that are at risk of flooding. The identification and extraction of urban footprint has become an important research topic and tool in city planning, transportation planning, urban simulation, 3D city modelling, and building change detection.
