3D City Model Berlin Spatial Data Infrastructure Berlin: The 3D City Model ERDF Project

Strategic Goal 3D City Model Berlin Strategic Goal Use of 3D City Model for: City and Urban Planning, Political Issues and Consulting, Civic Participation, Marketing, Service, Promotion for Companies Initial situation: two different models should be merged into one single model According to the GDI Berlin-Brandenburg Open Standards to be used to enable access Funded by European Regional Development Fund (ERDF): ca. 900,000

3D City Model Berlin Characteristics Characteristics Applications for Showroom and Urban Planning and updating ORACLE Database using CityGML Standard (Open Source Database Schema) Access through OGC Web Services, WPVS, GoogleEarth (kml), Online Streaming, Access Control by Web Security Service Integrates Objects in all Levels of Detail (LOD1-4) with Textures Wide Spectrum of Geodata (Laserscan, Orthografic, Architecture, POI)
