4 Why-What-How-When? Why? Users needs Needs of the society and savings Technology What? Multirepresentation database Aerial images and point clouds, DEM NTDB 3D: Some feature types like buildings NTDB 2,5: Most other features NTDB 2D NTDB generalized 2-: Generalized information Official /Citizens versions How? Network+ Programme + Projects When? 2018 v1 Start of the NTDB with first data 2023 v2 NTDB fully operational

5 Why? Users Data schema and content Quality (Positional Accuracy, Up-todateness) 3D 4D Easyness in updating Combining different data together Society Availability and sharing data (big investments in data ) -> data should be used Double data collecting Quality Linking processes Economy INSPIRE Technology Standards(CityGML, WFS)+ de facto standards Revolution in data collection(laserscanni ng + sensors) LinkedData Benchmarking: Switzerland,Netherlands,G ermany, Denmark, Norway, Sweden

6 NTDB is based on research Commón Datamodel between NLS and municipalities is exceptional as it can only be implemented with co-operation. However it has large impact even implementation will take long time Aalto University user organisations partcipated to the interviews, 3700 users to the web questionnaire and 18 experts to the expert interviews Doctoral theses multiple representation Tiina Sarjakoski, NTDB with municipalties Antti Jakobsson (2006) Ministry of Acgriculture NTDB 2030

12 New National Topographic Database (NTDB) Open and Linked Outcome of the opening data; co-operation between NLS and municipalities and other governmental agencies becomes a reality Savings in data collection and better quality for the citizens NLS can use data from the original source (planning, implementation and demolished objects) ID management Linked Data Address Roads NTDB Cadastre Municipalities Land Cover Hydrography Agriculture Companies

13 Municipalities role in NTDB Data producer Common data model NTDB City NTDB master or not? Common quality and quality process Data provider Basis for city model Savings in production New products and usage INSPIRE Access to other authorties Data user
