Abstract:

The 3D map for urban areas can be established from Terrestrial Laser Scanner derived data or from UAV photogrammetry data. The limitation of the land-based laser scanner is that it is unable to collect the data of the building’s roof, while that task is the advantage of the UAV photogrametry. This research proposed a method to combine two data sets acquired from land-base laser scanner and the UAV photogrametry for establishing 3D map of the city in to overcome the disadvantage of each data set. Result of data combilation demonstrated that it is able to establish the 3D map with scale 1:1000 for urban area according to the current standards. Besides, when using these technologies one can obtain high precision informattion of object and apply is information for different purposes in urban managemen
