Investigation on Basic Data of Urban Renewal of Guangzhou City Based on Multi-sensor Fusion
This paper focuses on the urban renewal basic data investigation work in Guangzhou City,and constructs a multi-sensor fusion basic urban renewal data investigation model with the orientation of cost reduction,efficiency improvement,and technological empowerment.It unifies the spatial benchmark cov-ering the whole city of Guangzhou,carries out satellite remote sensing,low-altitude photogrammetry,and ground-based multi-platform LiDAR observations,develops multi-source data collaborative processing al-gorithms,builds an integrated spatial data processing platform,automated area and ownership manage-ment software for building groups,and external industrial data collection mobile terminal.The model has the advantages of improving efficiency and reducing costs,and is of some reference significance for simi-lar projects.
