[ANONYMIZED AUTHORS, 3 June 2022] ------------------------------------------------------------------------------------------------------------- Data on different types of green spaces and their accessibility in the seven largest urban regions in Finland ------------------------------------------------------------------------------------------------------------- The coordinate reference system of all spatial data is ETRS-TM35FIN (EPSG:3067). See the data description article for full details. DATA FILES: ---------- green_spaces.gpkg water_bodies green_space_accessibility.gpkg green_space_accessibility.csv SOURCE DATA: ----------- - Functional Urban Regions in Finland with more than 100,000 inhabitants: Helsinki, Jyväskylä, Kuopio, Lahti, Oulu, Tampere and Turku: Urban Atlas (SYKE and EEA, 2018) - Urban core areas: continuous inner and outer urban areas combined as delineated in urban–rural classification (SYKE, 2020) - Raw data for green areas: Urban Atlas (SYKE and EEA, 2018) - Raw data for facilities and routes: LIPAS database (University of Jyväskylä, 2020) - Raw data for conservation areas: The nature protected areas and wilderness reserves dataset (Metsähallitus, 2021) - Raw data for pedestrian network: OpenStreetMap (OpenStreetMap Contributors, 2021) - Statistical grid: 250 m x 250 m grid (Statistics Finland and SYKE, 2021) - Raw data for water bodies: Ranta10 (SYKE and NLS, 2021) and Ranta250 (NLS and SYKE, 2017) GREEN SPACE QUALITY DATA green_spaces.gpkg & water_bodies.gpkg --------------------------------------------------------------- water_bodies.gpkg contains only a subset of these columns. | Column name | Description | |-------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | centr_id | Unique identifier of the green space polygons. 6 first digits represent the x-coordinate, 7 last digits reprsent the y-coordinate of the polygon centroid in ETRS-TM35FIN. | | region | Name of the functional urban area | | core | Whether the centroid of the green space belongs to the urban core area (1 = yes, 0 = no) | | area | The total area of the green space in hectares (ha) | | class | Land cover category of the green space (A–F) | | class_des | Description of the green space land cover categories: A = Forests B = Green urban areas C = Grasslands and open spaces with little vegetation D = Agricultural land E = Wetlands F = Land without current use | | forest_3ha | Whether the green space is a forest with a minimum size of 3 ha (1 = yes, 0 = no) | | forgua_1_5ha | Whether the green space is a forest or a green urban area with a minimum size of 1.5 ha (1 = yes, 0 = no) | | forgua_3ha | Whether the green space is a forest or a green urban area with a minimum size of 3 ha (1 = yes, 0 = no) | | green_1_5ha | Whether the green space (all categories) has a minimum size of 1.5 ha (1 = yes, 0 = no) | | green_3ha | Whether the green space (all categories) has a minimum size of 3 ha (1 = yes, 0 = no) | | green_5ha | Whether the green space (all categories) has a minimum size of 5 ha (1 = yes, 0 = no) | | green_10ha | Whether the green space (all categories) has a minimum size of 10 ha (1 = yes, 0 = no) | | green_cons | Whether the green space has a conservation status: at least 25% of the patch area is conserved (1 = yes, 0 = no) | | green_facilities | Whether the green space includes at least one facility (1 = yes, 0 = no) | | green_routes | Whether the green space includes at least one route (1 = yes, 0 = no) | | green_froutes | Whether the green space includes at least one facility and route (1 = yes, 0 = no) | | geometry | Geometry representation of the green space polygons in ETRS-TM35FIN coordinate reference system (EPSG:3067). | ACCESSIBILITY DATA green_space_accessibility.* (Geopackage & csv files) ----------------------------------------------------------------------- The accessibility data covers all grid squares across the functional urban areas. Network distances have been calculated up to 10 kilometers. Value range of the distance values is from zero to 9999 meters. Values >9999 are set to NULL. Distance values have been rounded up to the nearest meter(m). Value for grid squares having their centroid inside a green space have been set to 0.
