Provision of harmonized land cover information for lucas from the Finnish datasets Eurostat grant 2014 Provision of harmonized land cover/land use information: LUCAS and national systems Elise Järvenpää, Markus Haakana, Pekka Härmä, Minna Kallio, Riitta Teiniranta, Sakari Tuominen, Markus Törmä, Nina Vainikainen elise.jarvenpaa@ymparisto.fi

Project partners Consortium: Finnish Environment Institute (SYKE) and Natural Resources Institute Finland (Luke) SYKE maintains an environmental spatial data infrastructure (ESDI), which serves the whole environmental administration being the biggest INSPIRE data provider in Finland in numbers of different data sets and themes LUKE, the former Finnish Forest Research Institute METLA plus several other institutes, is responsible of the Finnish National Forest Inventory (NFI) National data providers have been invited to form an “advisory board” To guide the work of the project team To confirm that the results of the project are discussed in national level To ensure that results are better taken into account in development of national land monitoring Project duration 1.1.2015-30.6.2016

Main goal Land monitoring in Finland National high resolution CLC: raster with 20 m pixel size and national 4th level classes Land monitoring in Finland Several organizations are responsible for operational LC monitoring programmes Data is usually open & free of charge Information is integrated to produce spatial datasets Needs of the European Environment Agency are fulfilled (Corine Land Cover) Now also data needs of EUROSTAT taken into account Develop Finnish bottom-up-approach for LM so that also statistical datasets for Lucas survey could be produced Inventory of national datasets and classifications Development of methodology to get Lucas compatible data Concentration to land cover and objective 1 Which is generalized to European CLC: vector with 25 ha MMU Objective 1 concerns the provision of statistical data on land use and land cover, and information on the access and use conditions to national micro data Objective 2 concerns the integration of LUCAS into a national in-situ survey

Tasks from both objectives in 6 WPs WP1: Inventory of existing national data sources on land cover/use Assessment of their comparability to LUCAS classification WP2: Methodology development and technical solutions A method for data integration of various data sources is developed, tested and documented for a pilot area WP3: Results, metadata and quality assessment Statistical tables are produced in NUT levels covering the whole of Finland together with metadata and data quality is evaluated by comparing the results to other datasets WP4: Feasibility and accessibility aspects of micro data The feasibility of future updates using proposed and tested approach is evaluated including access and use conditions of the national datasets WP5: Information on additional micro data National field surveys are evaluated in order to estimate the possibility to cover any of in-situ components of LUCAS inside or parallel to national ongoing programmes. WP6: Analysis of the national in-situ survey Selected field survey (National Forest Inventory) is analysed in terms of objectives, methodology, schedule, organisation, data flow and quality assurance

WP1: The listing of available national GIS and in-situ data sets and data producers National high resolution (20m raster) CORINE land cover (SYKE) Copernicus IMAGE2012 High Resolution Layers Environmental Registers (SYKE) Register for sand pits and mining areas National forest inventory , (Luke) Different themes Agricultural Land parcel database LPIS (Agency for Rural affairs) Topographic Database (National Board of Survey) Different masks: buildings, other built-up areas, fields, soil Land parcel boundaries database (National Board of Survey) Building Information in Population Information System (Population register Centre) The national road and street database, Digiroad (Finnish Transport Agency) Reindeer pasture inventory (Game and Fisheries Research) Soil databases (Geological Survey of Finland)

WP1: Comparison of class definitions of Lucas and national datasets Cross tabulation of Lucas2012 microdata to all national and selected European Copernicus data layers To have an overview to how many Lucas points we can get a value from national datasets To identify the most problematic classes/areas Next step Comparison of class definitions of Lucas GT2014 in 2nd level and national land cover data sources class by class Continue the WP2 with the relevant national datasets

LUCAS not artificial land HRL Imperviousness LUCAS artificial land Aerial image HRL tree cover density HRL forest type

Oat (Lucas) Spring grain, oat (LPIS) Non-irrigated arable land (CLC HR20m)

Field /transitional woodland (CLC HR20m) ”Artificial” (Lucas) Field /transitional woodland (CLC HR20m) Only main roads were taken to CLC HR20m Narrow roads can be derived from Digiroad

WP 5: Assessing how LUCAS in-situ data can be collected in national surveys Finnish National Forest Inventory (NFI) Micro data on environmental parameters  Covered for all forestry land Transect data on land cover  No transects Photos  No photos Soil module Some soil data covered for forests Next step Assessing the feasibility of implementing the in-situ components not being covered in NFI

Next steps Continuation of WP1 and WP5 WP2 (Methodology development) will start in May 2015 The first meeting of the expert group of national data providers (advisory board) 3rd of June 2015 in SYKE The topic of the seminar is “The possibilities to contribute Lucas inventory with national land cover datasets” Field trip to Western Lappland in August 2015 Lucas survey and NFI survey
