The construction of as-built digital urbanscape - from building components to a city

摘要

The purpose of this research is to build digital urban landscape (or urbanscape), based on as-built environmental information. A long-range 3D laser scanner is used to record buildings, plants, and open spaces in static configuration, plus the records of pedestrians, vehicles, objects in dynamic form. Studies have extended to the record of 3D geometries into following information related issues, such as digital contents definition, land registration, urban element integration, characteristic abstraction, and scan "noise" made by pedestrians or vehicles for circulation system evaluation. In order to manage and display large amount of as-built data, the information system is made by 3D database, web pages with measuring function, as well as editing works for different data types and service possibilities.
