History of Geologic Survey Rock Types in Kuusamo, Finland

This table contains the version history of the rows extracted from the dataset sourced from the website of the 'Geological Survey of Finland', originating from the country with the ISO country code 'FI'. The table '_rajapinnat_gtk_kalliopera_wfskuusamo_tyypin_co_aukuusamotyypin_coauhistory' is derived from the base table '_rajapinnat_gtk_kalliopera_wfskuusamo_tyypin_co_au__kuusamotyypin_coau', and it includes additional columns '_start_date' and '_end_date'. The '_start_date' column contains the date when the row was extracted, while the '_end_date' column contains the date when a new version of the row was extracted. If the '_end_date' column has a null value, it indicates that the row is the most recent version. The table contains various columns such as 'gml_id', 'objectid', 'tracttype', 'tractname', 'number_dep_10_percent_prob', 'number_dep_50_percent_prob', 'number_dep_90_percent_prob', 'expected_number_of_dep', 'au_estim_10_percent_prob', 'au_estim_50_percent_prob', 'au_estim_90_percent_prob', 'au_mean_estimate', 'co_estim_10_percent_prob', 'co_estim_50_percent_prob', 'co_estim_90_percent_prob', 'co_mean_estimate', 'shape_area', 'shape_len', 'geom_geojson', 'geom_geotext', 'geom_type', 'geom_centroid', 'geom_center_x', and 'geom_center_y'. These columns include various data related to geology and surveys, such as the probability and estimated number of deposits, mean estimates, shape area and length, as well as various geometrical data. The historical data in this table can be utilized in data analytics to analyze changes over time, track trends, perform geospatial analysis, and gain insights into geological observations and patterns.
