The table in question is a historical record, which is part of a larger dataset collection. It is sourced from the 'Lantmäteriet' website, based in Sweden. The table holds version history for each of its base table rows, meaning it contains two additional columns compared to its base table to hold timestamps for when a row was extracted and when a new version was added. This feature makes this table unique as it allows for tracking changes over time, offering a timeline of the data evolution.

The table includes a unique combination of a start date and row number to distinctly identify every row. It also captures the date a new version of a row was added. If the end date field is empty, it indicates that the current row is the most recent version.

One of the notable aspects of this table is its geographic data, originally in shapefile format, an established method for storing geometric location and feature attribute information. The geographic data, which can be represented as points, lines, or polygons, has been converted into the final geographic format from the original shapefile format.

This historical table could be highly useful in data analytics. For instance, it could allow analysts to track changes in geographic features over time, providing a rich source of temporal spatial data. It could also be used to verify the accuracy of the current data by comparing it with previous versions. In addition, the unique identifier combination allows for precise data tracking and management, making the table an essential asset for any data management strategy.

Field Descriptions

Name Data type Description
_start_datedateContains the date when the row was extracted from the data source. It is part of a combination with '_row_number' that uniquely identifies each row in this version history table.
_end_datedateContains the date when a new version of the row was extracted from the data source. If its value is null, it signifies that the row is the most recent version.
_row_numberlongContains the number of the row in the raw data extracted from the data source. It forms a unique pair with '_start_date' to identify each row in this version history table.
OBJECTIDlongA unique identifier for each object in the table.
IDstringAn identifier for each entry in the table.
CODE_12stringA coded value representing a specific category or type of data.
Area_HadoubleThe area of a geographical feature represented in hectares.
RemarkstringField for additional information or comments about the row.
Shape_LengdoubleThe length of the geographical shape represented.
Shape_AreadoubleThe area of the geographical shape represented.
geom_geojsonstringThe geographical shape represented in GeoJSON format.
geom_geotextstringThe geographical shape represented in geotext format.
geom_typestringThe type of the geographical shape (for example, point, line, polygon).
geom_centroidstringThe centroid of the geographical shape.
geom_center_xdoubleThe x-coordinate of the center of the geographical shape.
geom_center_ydoubleThe y-coordinate of the center of the geographical shape.
