The table in question is a historical record, holding versions of data over time. This gives it a unique ability to track changes and trends, making it a valuable resource for analysis. It's a part of a dataset collection sourced from Lantmäteriet, a website based in Sweden. This table is unique in that it has two additional columns to its base table, indicating when a row was extracted and when a new version was created. If no end date is present, it signifies that the row is the most recent version. Each row is uniquely identified by a specific combination of its start date and row number. Furthermore, the table includes geographic data, initially in shapefile format - a common format for storing geometric location and attribute information of geographic features such as points, lines, or polygons. However, the geographic information has been converted into a final format for this dataset.

The data in this table has vast potential for use in data analytics. For instance, it could be used to track changes in geographic features over time by comparing different versions of the same row. It could also provide insights into the frequency and nature of updates made to the data source, by analysing the start and end dates. Lastly, the geographic data could be used in spatial analytics, aiding in understanding patterns and trends related to location.

Field Descriptions

Name Data type Description
_start_datedateThis indicates the date when the row was extracted from the data source. It is part of a unique identifier for each row in the version history table, along with '_row_number'.
_end_datedateThis is the date when a new version of the row was extracted from the data source. If the value of this column is null, it signifies that the row is the most recent version.
_row_numberlongThis represents the number of the row in the raw data extracted from the data source. Together with '_start_date', it uniquely identifies each row in this version history table.
OBJECTIDlongThis is a unique identifier for each object in the table.
IDstringThis column represents a unique identifier for each entry within the table.
CODE_12stringThis is a unique code associated with each row in the table.
Area_HadoubleThis represents the area of the object, measured in hectares.
RemarkstringThis column contains any additional comments or notes regarding the row.
Shape_LengdoubleThis indicates the length of the shape associated with each row.
Shape_AreadoubleThis represents the area of the shape associated with each row.
geom_geojsonstringThis contains the geometric representation of the object in GeoJSON format.
geom_geotextstringThis contains the geometric representation of the object as text.
geom_typestringThis indicates the type of the geometric object associated with each row.
geom_centroidstringThis contains the geometric center of the object.
geom_center_xdoubleThis represents the X coordinate of the object's geometric center.
