Content Background GIS technology review GIS technology strategy in action A case: Traffic Accidents GIS Technology Strategy in action in the near future 2.1.2019 Rina Tammisto

Background Promotion and creation of a legitimate status when noted in Statistics Finland’s GIS strategy (2014) Management of geospatial infrastructure, Relocation of personnel (to a GIS core team) and Founding of an in-house GIS expert group. ICT strategy for 2015 to 2018 Statistics Finland’s Strategy 2016-2019 Wider utilisation of GIS (to benefit customers) More visualisation (incl. maps) on the Web -> Recommendation that a GIS technology “Strategy” (or an action plan) should be carried out 2.1.2019 Rina Tammisto

GIS technology review

GIS technology review 9/2015-3/2016 The report Lists all GIS technologies used at Statistics Finland Is the used technology up-to-date? Has GIS been used in a natural and easy way in the production processes The report offered three alternative technological solutions on how to handle geospatial data and its requirements in data collection, production and dissemination. A so-called hybrid solution was chosen. The solution combines Open Source technologies with licensed GIS technologies. E.g., Open Source products were mainly the chosen solutions for server-side functionalities or for light thematic mapping purposes (Geoserver, QGis). By contrast, licensed products were chosen (ESRI ArcGIS, SAS, SQL Server spatial data type) for professional use, e.g., for spatial analysis or spatial data editing. Planned renewals of geospatial production and new techniques were combined with the Renewing of GIS technology at Statistics Finland (2016-2017) 2.1.2019 Rina Tammisto

Chosen technologies Chosen technologies by phases of the Generic Statistical Business Process Model (GSBPM) Chosen technologies 5. Process 4. Collect 6. Analyse 7. Dissemination 2.1.2019 Rina Tammisto

Seven GIS principles for future actions Geospatial code of practices THE GEOSPATIAL DIMENSION IS RECOGNISED AND GEOSPATIAL SOLUTIONS ARE MADE IN CONTROLLED MANNER USE HIGH-QUALITY GEOGRAPHIC DATA UTILISING GEOGRAPHIC DATA SERVICES AND SERVICE INTERFACES SPATIAL DIMENSION OF THE DATABASE IS WIDELY USED UTILISATION OF GEOSPATIAL DATA IS AN INTEGRATED AND AUTOMATED PART OF PRODUCTION OPEN SOURCE GIS SOFTWARE IN USE GEOSPATIAL DATA IS UTILISED AS MAP SERVICES EXPERT SUPPORT AVAILABLE FOR UTILISING GEOSPATIAL DATA 2.1.2019 Rina Tammisto

GIS technology strategy in action

GIS Technological Renewals project All decided reforms were gathered into one project. The project has four sub-projects: Oskari catalogue (Establishment of an Oskari infrastructure) GIS data catalogue Embedded maps Promoting links between published geospatial data and statistical data - and their metadata Introducing Open Source software for production: QGIS Designing QGIS to the technical environment of Statistics Finland Training and creating of support material (on the intranet) Information and guidance 2.1.2019 Rina Tammisto

Harmonisation of GIS related statistical production Promoting the use of SQL Server spatial data type Renewing of spatial databases (stop using Esri SDE) Renewing of production processes of core geospatial data (e.g. buildings and INSPIRE data) Creating a service-based (SOA) geocoding service Utilisation of service interfaces Creating descriptions of technical architecture – Service-based GIS application 2.1.2019 Rina Tammisto

Modernisation of statistics on Road Traffic Accidents Road Traffic Accidents renewed their statistical system in 2016: Use of QGIS in GIS related production phases SQL Server spatial data type is utilised for geocoding SQL Server spatial data type is used for searching descriptive data around traffic accidents spots by location Benefits: No Esri dependency anymore Faster to use A better known solution – developed by and from the point of view of the needs of statistics 2.1.2019 Rina Tammisto

1. Digiroad network can be used for locating the correct intersection The accident in question has happened in the intersection between Pälkänevedentie and Lahdentie 1. Digiroad network can be used for locating the correct intersection 2. Open street Map database can be used for locating the correct intersection 3. Correct place (4.) is then set with the tool that replaces coordinates with one click only Background aerial photo is provided by National Land Survey of Finland via wms-service Plugins are being used for the manual geocoding. Both internally developed and freely available plugins are being used for manual geocoding 2 January 2019 Etunimi Sukunimi

Lessons learned The GIS renewals are able to be implemented very fast The goals need to be clear from the point of view of The technology chosen The statistical production process in case Co-operation and support important between GIS professionals and statisticians A strong technological GIS support may be needed depends on the level of technical skills of the statisticians, in our Traffic Accident case, a light guidance was enough 2.1.2019 Rina Tammisto

GIS Technology Strategy in action in the near future

GIS Technology Strategy in action in the near future Renewing of population related statistics (STIINA)/A National Health, social services and regional government reform (SOTE) A new governmental decision-making level Development of Web services (the whole StatFi web infrastructure) -> New demands to handle location and areal information in statistical production processes (e.g. as linked data) -> For a coherent development in several statistical processes and web services - a project portfolio may be needed -> The chosen technological GIS solutions seem to be well in line with the needs - stand as the base infrastructure to build a new service layer on it 2.1.2019 Rina Tammisto
