Click here for a data sample
This table contains the version history of the 'rajapinnat_gtk_kalliopera_wfselektromagneettiset__elektromagneettiset' table sourced from the website of the Geological Survey of Finland (Geologian tutkimuskeskus). The table records the various versions of the base table, indicating the start and end dates of each version. Each row in the table represents a specific version of a row from the base table, with additional columns providing information such as the row number, GML ID, object ID, lineament ID, data source, certainty, scale, operator, date column, remarks, shape length, geometric data in GeoJSON and GeoText formats, geometry type, centroid coordinates, and the original geometry. The data in this table can be utilized for various data analytics purposes, such as tracking changes over time, analyzing data quality and reliability, identifying patterns or trends, and conducting spatial analysis. It provides valuable historical information about the base table, allowing users to explore the evolution of the underlying data. The data source 'Geologian tutkimuskeskus' originates from Finland (ISO country code: 'fi').
