This table contains information about the electromagnetic data from the Geologian tutkimuskeskus website in Finland. The table includes various fields such as the extraction date, row number, gml ID, object ID, lineament ID, data source, certainty, scale, operator, date column, remarks, shape length, geometry in GeoJSON and Geotext formats, geometry type, centroid location, center X and Y coordinates, and the full geometry. The data in this table can be utilized for various data analytics purposes, such as analyzing the distribution and characteristics of electromagnetic data, studying lineament patterns, identifying sources of the data, and performing spatial analysis based on the geometry information.
