Utilizing UAV for 3D Map for Urban Land Use in Tainan City, Taiwan

The progress of science and technology has changed the way of topographic mappingwhich is no longer limited to traditional ground and aerial photogrammetry. Unmanned ariel vechicle (UAV) is used to create image maps, light-probing maps, measurement vehicle scans as a new state of the art technology. Drone flight tests are different from traditional large aircraft aerial measurements. Drones are not affected by climate much and does not cause any casualty with good safety, low-altitude operation, obtaining high-precision images. They have wider building coverage. Using drones increases the multi-faceted texture image of buildings with enhaced scale up to 1:1000. The images from drones avoids cloud cover with low cost, easy operation and maintenance. Mapping is very important in geography, architecture and other fields, especially in urban planning. Thus, we combine UAV technology with urban planning to build a three-dimensional (3D) model from the original two-dimensional (2D) plane of the urban planning and economic zone. Geographic Information Systems (GIS) is also used for urban planning to facilitate subsequent application and treatment.
