The purpose of this research is to build digital urban landscape, based on as-built environmental information for cultural studies of old streets. Scans were made to the streets and facades in a famous sightseeing location, Yingge Old Street, on northern Taiwan. A 3D laser scanner was used to record buildings, plants, and open spaces in a static configuration starting from a bridge as the gateway to the city. The final urban information creates a precise description of objects with colors and textures feasible for internet browsing as well as for infrastructure illustration and measurement. Study was made to the second contour and the micro expression of the old streets which represents the cultural characteristics. A new design style as a new symbolic representation of the entrance to the old street was explored as a visual illustration that contrasts between modern design vocabulary and traditional old street components, or international style and traditional ceramic icons like brick chimney and pot walls. This study considers the local cultural icon should comprise objects with 3D as-built configuration as a best representation approach. 3D scan has proofed to be one of best approaches to achieve this goal.
