Case study

Producing 3D building models, realty cadastre mapping

Mapping urban areas with aerial sensors, producing building 3D models for construction monitoring and other city management processes.

Goals

Mapping urban areas with aerial sensors, producing building 3D models for construction monitoring and other city management processes.

Tasks

Assessments using aerial laser scanner and RGBN aerial digital camera, or oblique camera system; classifying buildings and producing CityGML compatible 3D building models, comparing results with actual realty cadastre database.

Applied technologies

End products

Height model of city objects

Potentials of the produced database

Next to the main applications - city management and realty cadastre monitoring – the city model means potential for other expert areas such as urban planning, education, telecommunication, tourism, transport development, city meteorology, etc.
