The purpose of this research is to build digital urban models by as-built environmental 3D scan data. Scans were made of a street and surrounding buildings for 5.5 km through the center of Taipei, Taiwan. A 3D long-range laser scanner was used to record buildings, landscapes, and open spaces. The scan tolerance was controlled in 4 mm/50 m. The final urban information creates a precise description of objects in a virtual environment with colors and textures feasible for internet browsing, infrastructure dimensioning, and construction monitoring. A 3D representation of scan noise, in terms of pedestrian pattern in front of Taipei Metro, was conducted to illustrate the response of human flow to obstacles.
