Statewide Web Services & CityGML State roads CityGML (WFS) ATKIS railways CityGML (WFS) CityGML block models LOD1 (WFS-T) ATKIS roads CityGML (WFS) DTM GeoTIFF (WCS) source: LVermA NRW, Stapelfeldt GmbH
Why? EU Environmental Noise Directive 2002 (5 years iterations, statewide, great amount/multitude of 3D geodata) Implementation in due time, due professional requirements, cost-efficiency and sustainability Interoperability of heterogeneous amount of statewide 3D geodata (10Mio buildings, 34.083 km² in NRW) Geodata acquisition & integration highest expenditure of time (90%) Highest saving potentials in 3D geodata provision SDI strategy allows mix of centralised (state agency) and decentralised (agglomerations) noise processing High requirements on geodata refining - SDI allows flexible data update (7/24) transactional web services
Statewide geodata, no texture Goals & Benefits Sustainable data provision and generation Input and output data for multiple applications (no single use) No multiple data provision No manual data distribution (to 384 municipalities in NRW) Continuation only of original data High performance of web services 13 project partners in distributed responsibilities High financial savings in geodata aquisition and integration Noise mapping/data refining based on distributed data storage (SDI NRW) Realisation of entire value chain: geobasisdata aquisition provision refining generation of value added product (noise map)
