Land Use Green Areas in Helsinki, Finland

The dataset collection consists of one or more dataset tables sourced from the website of Helsingin kaupunkiympäristön toimiala in Finland.

Tables

Land Use Green Areas - Metropolitan Land Use Green AreasTSV
This table contains data on green areas in the metropolitan area. The data includes information on the extract date, row number, land use, land use group, geometric representation in GeoJSON and geotext format, geometric type, centroid coordinates, center X and Y coordinates, full geometry, and a data service identifier. The table provides valuable data for data analytics tasks such as analyzing the distribution and characteristics of green areas in the metropolitan area, studying the relationship between land use and green spaces, identifying the geometric properties of these areas, and analyzing their spatial distribution. The table is sourced from the website of Helsingin kaupunkiympäristön toimiala (City of Helsinki Environment Department) which originates from the country with ISO...
Open Urban Data Map Land Use Green Areas - HistoryTSV
This table contains the version history of rows from the 'avoindataseutukartta_maankaytto_viheralueet__seutukartta_maankaytto_viheralueetpolygon' base table. Each row in this table represents a specific version of a row from the base table, with additional columns '_start_date' and '_end_date' indicating the extraction dates. The data in this table provides valuable information for data analytics tasks. For example, it can be used to analyze changes in land use ('maankaytto') and its corresponding master group ('mtryhm') over time. With the 'geom_geojson' column, the geographic features of the green areas can be visualized and analyzed. The 'geom_type' column provides information about the type of geometry used to represent the geographic features. The 'geom_centroid', 'geom_center_x',...
