Version History of Kalliopera 10m Meteorite Impact Area
Click here for a data sample
This table contains the version history of the rows extracted from the 'Geological Survey of Finland' website for the 'rajapinnat_gtk_kalliopera_wfskalliopera_10m_meteoriitti_iskemia__kalliopera_10m_meteoriitti_iskemia' table. It includes information such as the start and end dates of each row version, a unique row number, 'gml_id' and 'objectid' identifiers, the name of the data, the geometry in GeoJSON and Geotext formats, the type of the geometry, the centroid coordinates, and the original geometry. The data in this table can be utilized for various data analytics purposes, such as analyzing the changes in meteorite impact features over time, studying geospatial patterns of meteorite iskemia on a 10-meter scale, and identifying the central points of the geometries. This data is sourced from the web site of the Geological Survey of Finland, which originates from Finland (ISO country code: 'fi').
